.NET的Network Tracing 机制

本文主要是介绍.NET的Network Tracing 机制，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

程序之间通信跟踪：

------------------------被测程序 Sample Start ----------------------------------------------------

using System.Diagnostics;

using System.Net;
using System.Net.Sockets;

private void Sample()
        {
            UdpClient client = new UdpClient(10000);
            try
            {
                client.Connect("www.google.com", 10000);
                byte[] sendBytes = Encoding.ASCII.GetBytes("Hello?");
                client.Send(sendBytes, sendBytes.Length);

                client.Close();
            }
            catch (Exception e)
            {
                // Todo : Exeception handle
             }
        }

--------------------end-----------------------------------------------

Network Tracing 提供了访问托管程序产生的网络通信信息，以及网络方法的调用信息机制。要利用这种机制，需要添加如下的配置文件：

---------------------App.config-----------------------------------------

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.diagnostics>
    <sources>
      <source name="System.Net" tracemode="includehex" maxdatasize="1024">
        <listeners>
          <add name="System.Net"/>
        </listeners>
      </source>
      <source name="System.Net.Sockets">
        <listeners>
          <add name="System.Net"/>
        </listeners>
      </source>
      <source name="System.Net.Cache">
        <listeners>
          <add name="System.Net"/>
        </listeners>
      </source>
    </sources>
    <switches>
      <add name="System.Net" value="Verbose"/>
      <add name="System.Net.Sockets" value="Verbose"/>
      <add name="System.Net.Cache" value="Verbose"/>
    </switches>
    <sharedListeners>
      <add name="System.Net"
        type="System.Diagnostics.TextWriterTraceListener"
        initializeData="network.log"
      />
    </sharedListeners>
    <trace autoflush="true"/>
</system.diagnostics>
</configuration>

--------------------------end ------------------------------------------------

在主程序中调用Sample(),将会在当前目录下生成network.log的文件，

----------------------------network.log------------------------------------------
