C#实现写系统日志的方法
本文实例讲述了C#实现写系统日志的方法。分享给大家供大家参考。具体实现方法如下：
usingSystem;
usingSystem.Collections.Generic;
usingSystem.Linq;
usingSystem.Text;
usingSystem.Diagnostics;
namespaceConsoleApp
{
///<summary>
///系统日志
///</summary>
publicclassPackSystemEventLog
{
///<summary>
///错误信息
///</summary>
privatestaticstringErrorInfo{get;set;}
///<summary>
///创建系统事件日志分类
///</summary>
///<paramname="eventSourceName">注册事件源(比如说这个日志来源于某一个应用程序)</param>
///<paramname="logName">日志名称(事件列表显示的名称)</param>
///<returns></returns>
publicstaticboolCreateSystemEventLogCategory(stringeventSourceName,stringlogName)
{
boolcreateResult=false;
try
{
if(!EventLog.SourceExists(eventSourceName))
{
EventLog.CreateEventSource(eventSourceName,logName);
}
createResult=true;
}
catch(Exceptionex)
{
createResult=false;
ErrorInfo=ex.Message;
}
returncreateResult;
}
///<summary>
///删除系统事件日志分类
///</summary>
///<paramname="eventSource">EventName事件源</param>
///<returns></returns>
publicstaticboolRemoveSystemEventSourceCategory(stringeventSource)
{
boolcreateResult=false;
try
{
if(EventLog.SourceExists(eventSource))
{
EventLog.DeleteEventSource(eventSource,".");
}
createResult=true;
}
catch(Exceptionex)
{
createResult=false;
ErrorInfo=ex.Message;
}
returncreateResult;
}
///<summary>
///向系统日志中写入日志
///</summary>
///<paramname="eventSource">事件源</param>
///<paramname="msg">写入日志信息</param>
///<paramname="type">日志文本分类(警告、信息、错误)</param>
///<returns></returns>
publicstaticboolWriteSystemEventLog(stringeventSource,stringmsg,EventLogEntryTypetype)
{
boolwriteResult=false;
try
{
if(!EventLog.SourceExists(eventSource))
{
writeResult=false;
ErrorInfo="日志分类不存在!";
}
else
{
EventLog.WriteEntry(eventSource,msg,type);
writeResult=true;
}
}
catch(Exceptionex)
{
writeResult=false;
ErrorInfo=ex.Message;
}
returnwriteResult;
}
///<summary>
///删除事件源中logName(好像删除了所有的该分类的日志)
///</summary>
///<paramname="eventSource"></param>
///<paramname="logName"></param>
///<returns></returns>
publicstaticboolRemoveSystemEventLog(stringeventSource,stringlogName)
{
boolremoveResult=false;
try
{
if(!EventLog.SourceExists(eventSource))
{
removeResult=false;
ErrorInfo="日志分类不存在!";
}
else
{
EventLog.Delete(logName);
removeResult=true;
}
}
catch(Exceptionex)
{
removeResult=false;
ErrorInfo=ex.Message;
}
returnremoveResult;
}
///<summary>
///获取错误信息
///</summary>
///<returns></returns>
publicstaticstringGetErrorMessage()
{
returnErrorInfo;
}
}
}
希望本文所述对大家的C#程序设计有所帮助。
