TraceSource类的前身是Trace与Debug。在项目的实际使用过程中，一般通过以下步骤使用：

【1】定义配置文件.Config -- 配置TraceSource的源、控制级别、监听器等

**\[html\]**  [view plain][] [copy][view plain] [print][view plain] [?][view plain]

1.  **<?****xml** version="1.0" encoding="utf-8" **?>**  
2.  **<****configuration****>**  
3.      
4.    **<****system.diagnostics****>**  
5.        
6.      **<****sources****>**  
7.        **<****source** name="LogTrace" switchName="LogTraceSourceSwitch" switchType="System.Diagnostics.SourceSwitch" **>**  
8.          **<****listeners****>**  
9.            **<****add** name="textListener" **/>**  
10.           **<****remove** name ="Default" **/>**  
11.         **</****listeners****>**  
12.       **</****source****>**  
13.     **</****sources****>**  
14.       
15.     **<****switches****>**  
16.         
17.       **<****add** name="LogTraceSourceSwitch" value="Information" **/>**  
18.         
19.         
20.     **</****switches****>**  
21.       
22.     **<****sharedListeners****>**  
23.       **<****add** name="textListener" type="System.Diagnostics.TextWriterTraceListener" initializeData="trace.log"**>**  
24.           
25.         **<****filter** type="System.Diagnostics.EventTypeFilter" initializeData="Warning" **/>**  
26.       **</****add****>**  
27.     **</****sharedListeners****>**  
28.       
29.     **<****trace** autoflush="true" indentsize="4" **/>**      
30.   **</****system.diagnostics****>**  
31.     
32. **</****configuration****>**

【2】定义TraceSource对象，可以简单封装

**\[csharp\]**  [view plain][] [copy][view plain] [print][view plain] [?][view plain]

1.  **using** System;  
2.  **using** System.Collections.Generic;  
3.  **using** System.Linq;  
4.  **using** System.Text;  
5.  **using** System.Diagnostics;  
6.    
7.  **namespace** LogTrace.Log  
8.  \{  
9.      **class** CLog  
10.     \{  
11.         **public** **static** **void** LogCritical(**string** strMessage)  
12.         \{  
13.             \_ts.TraceEvent(TraceEventType.Critical,  
14.                            0,  
15.                            "   \[\{0\}\{1\}\]: \{2\}",   
16.                            DateTime.Now.ToLongDateString(),   
17.                            DateTime.Now.ToLongTimeString(),   
18.                            strMessage);         
19.         \}  
20.   
21.         **public** **static** **void** LogError(**string** strMessage)  
22.         \{  
23.             \_ts.TraceEvent(TraceEventType.Error,  
24.                            0,  
25.                            "      \[\{0\}\{1\}\]: \{2\}",  
26.                            DateTime.Now.ToLongDateString(),  
27.                            DateTime.Now.ToLongTimeString(),  
28.                            strMessage);              
29.         \}  
30.   
31.         **public** **static** **void** LogWarning(**string** strMessage)  
32.         \{  
33.             \_ts.TraceEvent(TraceEventType.Warning,  
34.                            0,  
35.                            "    \[\{0\}\{1\}\]: \{2\}",  
36.                            DateTime.Now.ToLongDateString(),  
37.                            DateTime.Now.ToLongTimeString(),  
38.                            strMessage);              
39.         \}  
40.   
41.         **public** **static** **void** LogInformation(**string** strMessage)  
42.         \{  
43.             \_ts.TraceEvent(TraceEventType.Information,  
44.                             0,  
45.                            "\[\{0\}\{1\}\]: \{2\}",  
46.                            DateTime.Now.ToLongDateString(),  
47.                            DateTime.Now.ToLongTimeString(),  
48.                            strMessage);               
49.         \}         
50.   
51.         **private** **static** TraceSource \_ts = **new** TraceSource("LogTrace");  
52.     \}  
53. \}

【4】编写测试代码

**\[csharp\]**  [view plain][] [copy][view plain] [print][view plain] [?][view plain]

1.  **using** System;  
2.  **using** System.Collections.Generic;  
3.  **using** System.Linq;  
4.  **using** System.Text;  
5.  **using** LogTrace.Log;  
6.    
7.  **namespace** LogTrace  
8.  \{  
9.      **class** Program  
10.     \{  
11.         **static** **void** Main(**string**\[\] args)  
12.         \{  
13.             CLog.LogCritical("Video Play()");  
14.             CLog.LogError("Audio Play()");  
15.             CLog.LogWarning("Picture Play()");  
16.             CLog.LogInformation("SubTitle Play()");  
17.         \}  
18.     \}  
19. \}

【5】测试结果
