choost与iif的注意点

2015 年 11 月 04 日 by enjoyasp.net·已关闭评论

对于多值函数，但值类型不一致时，则以第一个为主进行转换
如：


SELECT CHOOSE(2,1.0,'0.25')   --0.3

SELECT IIF(2>3,1.0,'0.25') --0.3

当类型不一致时要转换

SELECT CHOOSE(2,1,CONVERT(DECIMAL(8,2),'0.25') )  --0.3

读取xml报16进制字符错误

2015 年 10 月 21 日 by enjoyasp.net·已关闭评论

读取xml报16进制字符错误，因为xml文件中包括特殊字符，如u0018,造成解析错误
解析方法：剔除xml特殊字符再读取

  private string RemoveInvalidXmlChars(string text)
        {
            var validXmlChars = text.Where(ch => XmlConvert.IsXmlChar(ch)).ToArray();
            return new string(validXmlChars);
        }

private void OnRecvMessage(string Message) //接收到插件发来的消息触发该事件
        {
            try
            {
                RtxMessage rm = new RtxMessage();
              
                StringReader sr1 = new StringReader(RemoveInvalidXmlChars(Message.Content));//避免0/这种异常字符
                XmlReader xr1 = XmlTextReader.Create(sr1); // xr1's type is XmlTextReaderImpl

                while (xr1.Read())
                {
                    if (xr1.Name == "Item")
                    {

                        switch (xr1["Key"])
                        {
                            case "Mode": { if (xr1.Read()) { rm.Mode = xr1.Value; }; break; }
                            case "Content": { if (xr1.Read()) { rm.Content = GetContent(xr1.Value); }; break; }
                            case "Initiator": { if (xr1.Read()) { rm.Initiator = xr1.Value; }; break; }
                            case "Key": { if (xr1.Read()) { rm.Key = xr1.Value; }; break; }
                            case "Title": { if (xr1.Read()) { rm.Title = xr1.Value; }; break; }
                            case "im_message_id": { if (xr1.Read()) { rm.im_message_id = xr1.Value; }; break; }
                            default: { break; }
                        }
                    }
                }

             
            }
            catch (COMException xe)
            {
               
            }

        }

quarz+topself实现调度

2015 年 10 月 17 日 by enjoyasp.net·已关闭评论

quarz:用来灵活的调度程序的执行
topself:用来将应用提升为服务

一，建立控制台应用程序，引用右键添加：quarz.net，topself,topself.log4Net

二，main中添加代码，用topself承接程序的管理

using System
using Quartz;
using Topshelf;
using System.IO;

namespace Quarz
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                log4net.Config.XmlConfigurator.ConfigureAndWatch(new FileInfo(AppDomain.CurrentDomain.BaseDirectory + "log4net.config"));
                HostFactory.Run(x =>
                {
                    x.UseLog4Net();//记录topself自己产生的日志

                    x.Service<ServiceRunner>(); //ServiceRunner是quarz的调度程序，以此来调用

                    x.SetDescription("自己的WindowsService调度中心");
                    x.SetDisplayName("CedarQuarz");
                    x.SetServiceName("CedarQuarz");

                    x.EnablePauseAndContinue();
                });

            }
            catch (SchedulerException se)
            {
                Console.WriteLine(se);
            }
        }
    }
}

//ServiceRunner.cs如下
using Quartz;
using Quartz.Impl;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Topshelf;

namespace Quarz
{
    public sealed class ServiceRunner : ServiceControl, ServiceSuspend
    {
        private readonly IScheduler scheduler;

        public ServiceRunner()
        {
            scheduler = StdSchedulerFactory.GetDefaultScheduler();//调用调度计划,在quarz_job.xml配置要执行的job
        }

        public bool Start(HostControl hostControl)
        {
            scheduler.Start();
            return true;
        }

        public bool Stop(HostControl hostControl)
        {
            scheduler.Shutdown(false);
            return true;
        }

        public bool Continue(HostControl hostControl)
        {
            scheduler.ResumeAll();
            return true;
        }

        public bool Pause(HostControl hostControl)
        {
            scheduler.PauseAll();
            return true;
        }


    }
}
//自己写的job实现ijob即可
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Quartz;
using System.Threading.Tasks;
using RTXSAPILib;
using System.Configuration;
using System.Data;
using System.Data.SqlClient;


namespace Quarz
{
    class RtxSendMsg : IJob
    {
        private static RTXSAPILib.IRTXSAPIRootObj _RootObj;
        public static RTXSAPILib.IRTXSAPIRootObj RootObj {
            get {
                if (_RootObj == null) {
                    _RootObj = new RTXSAPIRootObj();
                }
                return _RootObj;
            }
        }

        public static string ServerIP= ConfigurationSettings.AppSettings["RtxServerIP"];
        public static short ServerPort = short.Parse(ConfigurationSettings.AppSettings["RtxServerPort"]);
        public static string ConnString = ConfigurationSettings.AppSettings["constring"];
        public static log4net.ILog log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

        public void Execute(IJobExecutionContext context)
        {
            log.Info("开始");
            //初始化服务器属性
            try
            {
                RootObj.ServerIP =   ServerIP;
                RootObj.ServerPort = ServerPort; //设置服务器端口
                DataTable dt = GetWaitNotifyInfo();
                if (dt == null || dt.Rows.Count == 0) return;
                foreach (DataRow dr in dt.Rows)
                {
                    SendNotify(StringHelper.FormatObjToString(dr["receiverAccount"]),
                        StringHelper.FormatObjToString(dr["CustomerID"]),
                        StringHelper.FormatObjToString(dr["CustomerName"]),
                        StringHelper.FormatObjToString(dr["D_StartTime"]),
                        StringHelper.FormatObjToString(dr["title"]), StringHelper.FormatObjToInt(dr["holdtime"]), StringHelper.FormatObjToString(dr["content"]));
                }
            }
            catch (Exception e) {
                log.Error(e.StackTrace.ToString());
            }
            log.Info("结束");
            //SendNotify("zhengxuesong", "hello", "", "【未接来电】客户65871于2015-10-16 14：10打来电话，请及时跟进");
        }

        public DataTable GetWaitNotifyInfo() {
            SqlParameter[] storedParams =
             {
                new SqlParameter("@Code",""),
                new SqlParameter("@UserID","")
            };
            IDataReader idr = Share.Data.SqlHelper.ExecuteReader(ConnString,
                  CommandType.StoredProcedure,
                  "GetWaitNotifyInfo",
                  storedParams);
            DataTable dt = new DataTable();
            dt.Load(idr);
            return dt;
        }

        public static void SendNotify(string receiverAccount, string CustomerID, string CustomerName, string D_StartTime,  string title, int holdtime, string content)
        {

            try
            {
                if (!RootObj.UserManager.IsUserExist(receiverAccount)) {
                    log.Warn(string.Format("{0}在腾讯通里不存在！", receiverAccount));
                    return ;
                };
                RootObj.SendNotify(receiverAccount, title, holdtime, content); //获取版本信息
                log.Info(string.Format("{0},{1},{2},{3},{4},{5},{6}", receiverAccount, CustomerID, CustomerName, D_StartTime, title, holdtime, content));
            }
            catch (Exception xe)
            {
                log.Error(xe.StackTrace.ToString());

            }

        }

    }
}

三，在app.config中指定job配置的xml文件，触发器的规格见文档

  <quartz>
    <add key="quartz.scheduler.instanceName" value="ExampleDefaultQuartzScheduler"/>
    <add key="quartz.threadPool.type" value="Quartz.Simpl.SimpleThreadPool, Quartz"/>
    <add key="quartz.threadPool.threadCount" value="10"/>
    <add key="quartz.threadPool.threadPriority" value="2"/>
    <add key="quartz.jobStore.misfireThreshold" value="60000"/>
    <add key="quartz.jobStore.type" value="Quartz.Simpl.RAMJobStore, Quartz"/>
    <!--******************************Plugin配置********************************************* -->
    <add key="quartz.plugin.xml.type" value="Quartz.Plugin.Xml.XMLSchedulingDataProcessorPlugin, Quartz" />
    <add key="quartz.plugin.xml.fileNames" value="~/quartz_jobs.xml"/>
  </quartz>

四，quartz_jobs.xml如下

<?xml version="1.0" encoding="UTF-8"?>

<!-- This file contains job definitions in schema version 2.0 format -->

<job-scheduling-data xmlns="http://quartznet.sourceforge.net/JobSchedulingData" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.0">

  <processing-directives>
    <overwrite-existing-data>true</overwrite-existing-data>
  </processing-directives>

  <schedule>

    <!--TestJob测试 任务配置-->
    <job>
      <name>RtxSendMsg</name>
      <group>Rtx</group>
      <description>向rtx发送提醒</description>
      <job-type>Quarz.RtxSendMsg,Quarz</job-type>
      <durable>true</durable>
      <recover>false</recover>
    </job>
    <trigger>
      <cron>
        <name>向rtx发送提醒每10分钟</name>
        <group>Rtx</group>
        <job-name>RtxSendMsg</job-name>
        <job-group>Rtx</job-group>
        <start-time>2015-01-22T00:00:00+08:00</start-time>
        <cron-expression>0 0/10 * * * ?</cron-expression>
      </cron>
    </trigger>

  </schedule>
</job-scheduling-data>

五，注册服务在bin下执行

 myapp.exe install
 myapp.exe start
 myapp.exe stop
 myapp.exe uninstall

log4j.net写入日志到sqlserver

2015 年 10 月 17 日 by enjoyasp.net·已关闭评论

log4j.net用了好久，没有总结过，这次做个记录。
作用：可以缓存多少条再写入库，哪些写入哪些不写入可以配置

一，log4j.net诊断
在web.config或者app.config中增加：

  <system.diagnostics>
    <trace autoflush="true">
      <listeners>
        <add
          name="textWriterTraceListener"
          type="System.Diagnostics.TextWriterTraceListener"
          initializeData="C:testlog4net.txt" />
      </listeners>
    </trace>
  </system.diagnostics>

  <appSettings>
    <add key="log4net.Internal.Debug" value="true"/>
    </appSettings >

二，写入sqlserver
1,启动时加载

log4net.Config.XmlConfigurator.ConfigureAndWatch(new FileInfo(AppDomain.CurrentDomain.BaseDirectory + "log4net.config"));

2，页面中使用：

public static log4net.ILog log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
log.Error(e.StackTrace.ToString());

3,数据库里建表

USE [K8]

/****** Object: Table [dbo].[Log4j] Script Date: 2015/10/17 18:37:59 ******/

SET ANSI_NULLS ON

SET QUOTED_IDENTIFIER ON

SET ANSI_PADDING ON

CREATE TABLE [dbo].[Log4j](

[ID] [INT] IDENTITY(1,1) NOT NULL,

[Thread] [VARCHAR](255) NOT NULL,

[Logger] [VARCHAR](255) NOT NULL,

[Date] [DATETIME] NOT NULL,

[Level] [VARCHAR](20) NOT NULL,

[Message] [VARCHAR](4000) NOT NULL,

CONSTRAINT [PK_Log4j] PRIMARY KEY CLUSTERED

(

[ID] ASC

)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]

) ON [PRIMARY]

SET ANSI_PADDING OFF

4，log4net.config配置如下

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
  </configSections>

据mdf方件查看数据库名称，版本信息

2015 年 09 月 17 日 by enjoyasp.net·已关闭评论

dbcc checkprimaryfile('E:dba1.mdf',2)

Syntax:DBCC CHECKPRIMARYFILE ({'PhysicalFileName'} [,opt={0|1|2|3}])

PhysicalFileName is the full path for the primary database file.

opt=0 - checks if the file a primary database file. 
opt=1 - returns name, size, maxsize, status and path of all files associated to the database.
opt=2 - returns the database name, version and collation.
opt=3 - returns name, status and path of all files associated with the database.
