我要评论本文实例讲述了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。
