如何将事件日志写到应用程序日志?安全日志?系统日志中?100分

asp.net中当服务器出错时显示指定的错误页面同时把错误信息写入系统日志文件的探讨一，在Web.config中填写出错时显示的页面，可以根据不同的statusCode显示不同的出错页面。
<customErrors mode="On" //如果设置为Off则出错只返回错误信息，不会跳到自己的指定页面defaultRedirect="/error/customerrorpage.aspx">
<error statusCode="404" redirect="/error/404Page.aspx"/>
<error statusCode="403" redirect="/error/403page.aspx"/>
</customErrors> 二,在Global.asax文件中添加应用出错代码，写入系统日志文件
protected void Application_Error(Object sender, EventArgs e)
{
Exception LastError = Server.GetLastError();
String ErrMessage = LastError.ToString();String LogName = "MyLog";
String Message = "Url " + Request.Path + " Error: " + ErrMessage;// Create Event Log if It Doesn't Existif (!EventLog.SourceExists(LogName))
{
EventLog.CreateEventSource(LogName, LogName);
}
EventLog Log = new EventLog();
Log.Source = LogName;
//These are the five options that will display a different icon.
Log.WriteEntry(Message, EventLogEntryType.Information, 1);
Log.WriteEntry(Message, EventLogEntryType.Error, 2);
Log.WriteEntry(Message, EventLogEntryType.Warning, 3);
Log.WriteEntry(Message, EventLogEntryType.SuccessAudit, 4);
Log.WriteEntry(Message, EventLogEntryType.FailureAudit, 5);}
三，现在你可以进行测试了。
我在Default.aspx.cs中产生一个错误，果然跳到默认的错误页面！
private void Page_Load(object sender, System.EventArgs e)
{
// Put user code to initialize the page here
try
{
int y=0;
int x=1/y;
}
catch (Exception Err)
{
throw new Exception("404");//我想产生不同的错误，对应web.config中的statusCode,该如何实现？
//Err.
}

EventLog 类
提供与 Windows 事件日志的交互。

private System.ComponentModel.Container components = null; public Form1()
{
//
// Windows 窗体设计器支持所必需的
//
InitializeComponent(); //
// TODO: 在 InitializeComponent 调用后添加任何构造函数代码
//
MyLog = new System.Diagnostics.EventLog("Log");
MyLog.Log = "我的日志";
MyLog.Source = "source";
if (EventLog.Exists("我的日志"))
button4.Enabled = true;
else
button4.Enabled = false;

using System.Diagnostics;再方法中EventLog eventLog=new EventLog("Application",".");
eventLog.source="eventlogname";
eventLog.WriteEntry("message",EventLogEntryType.Error);
还有好多，自己摸索

用Application可以写入应用程序日志,而
安全日志?系统日志中?

看看帮助里的：
Visual Basic 和 Visual C#/使用组件编程/创建系统监视组件里的内容，希望有帮助

as long as you give ASPNET enough privileges (for example, change userName in <processModel> in machine.config to "SYSTEM") or use impersonation, you can write to anythingEventLog's constructor takes a string which can be "System" and "Security", seehttp://support.microsoft.com/default.aspx?scid=kb%3Ben-us%3B329291http://www.4guysfromrolla.com/webtech/chapters/ASPNET2/ch02.9.shtml
