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：

using system;
using system.collections.generic;
using system.linq;
using system.text;
using system.diagnostics;
namespace consoleapp
{
 /// <summary>
 /// 系统日志
 /// </summary>
 public class packsystemeventlog
 {
  /// <summary>
  /// 错误信息
  /// </summary>
  private static string errorinfo { get; set; }
  /// <summary>
  /// 创建系统事件日志分类
  /// </summary>
  /// <param name="eventsourcename">注册事件源(比如说这个日志来源于某一个应用程序)</param>
  /// <param name="logname">日志名称(事件列表显示的名称)</param>
  /// <returns></returns>
  public static bool createsystemeventlogcategory(string eventsourcename, string logname)
  {
   bool createresult = false;
   try
   {
    if (!eventlog.sourceexists(eventsourcename))
    {
     eventlog.createeventsource(eventsourcename, logname);
    }
    createresult = true;
   }
   catch (exception ex)
   {
    createresult = false;
    errorinfo = ex.message;
   }
   return createresult;
  }
  /// <summary>
  /// 删除系统事件日志分类
  /// </summary>
  /// <param name="eventsource">eventname事件源</param>
  /// <returns></returns>
  public static bool removesystemeventsourcecategory(string eventsource)
  {
   bool createresult = false;
   try
   {
    if (eventlog.sourceexists(eventsource))
    {
     eventlog.deleteeventsource(eventsource, ".");
    }
    createresult = true;
   }
   catch (exception ex)
   {
    createresult = false;
    errorinfo = ex.message;
   }
   return createresult;
  }
  /// <summary>
  /// 向系统日志中写入日志
  /// </summary>
  /// <param name="eventsource">事件源</param>
  /// <param name="msg">写入日志信息</param>
  /// <param name="type">日志文本分类(警告、信息、错误)</param>
  /// <returns></returns>
  public static bool writesystemeventlog(string eventsource, string msg, eventlogentrytype type)
  {
   bool writeresult = 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 (exception ex)
   {
    writeresult = false;
    errorinfo = ex.message;
   }
   return writeresult;
  }
  /// <summary>
  /// 删除事件源中logname(好像删除了所有的该分类的日志)
  /// </summary>
  /// <param name="eventsource"></param>
  /// <param name="logname"></param>
  /// <returns></returns>
  public static bool removesystemeventlog(string eventsource, string logname)
  {
   bool removeresult = false;
   try
   {
    if (!eventlog.sourceexists(eventsource))
    {
     removeresult = false;
     errorinfo = "日志分类不存在!";
    }
    else
    {
     eventlog.delete(logname);
     removeresult = true;
    }
   }
   catch (exception ex)
   {
    removeresult = false;
    errorinfo = ex.message;
   }
   return removeresult;
  }
  /// <summary>
  /// 获取错误信息
  /// </summary>
  /// <returns></returns>
  public static string geterrormessage()
  {
   return errorinfo;
  }
 }
}
