1. 在App.Config中添加如下行：

[XML]

<?xml version="1.0"encoding="utf-8"?> <configuration>     <system.diagnostics>         <switches>             <addname="XPO"value="3"/>         </switches>     </system.diagnostics> </configuration>

2. 如果想記錄到一個檔案

在應用程式的配置檔案中加入：

<?xml version="1.0"encoding="utf-8"?> <configuration>     <system.diagnostics>         <traceautoflush="true"indentsize="4">             <listeners>                 <addname="LogFileTraceListener"type="System.Diagnostics.TextWriterTraceListener"                     initializeData="trace.log"/>                 <removename="Default"/>             </listeners>         </trace>         <switches>             <addname="XPO"value="3"/>         </switches>     </system.diagnostics> </configuration>

3. 使用 System.Diagnostics trace logging 機制

System.Diagnostics.Trace.Listeners.Add(newMyTraceListner(textBox1)); ... class MyTraceListner:System.Diagnostics.TraceListener{     TextBox outputWindow;     public MyTraceListner(TextBoxoutputWindow){         this.outputWindow=outputWindow;     }     public overridevoidWrite(stringmessage){         outputWindow.AppendText(message);     }     public overridevoidWriteLine(stringmessage){         outputWindow.AppendText(message+"\r\n");     } }
