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;
}
}
}
希望本文所述对大家的C#程序设计有所帮助。
