ASP.NET 记录页面错误及自定义错误页

 

protected override void OnError(EventArgs e)

{

// At this point we have information about the error

HttpContext ctx = HttpContext.Current;

Exception exception = ctx.Server.GetLastError();

string errorInfo = "错误URL: " + ctx.Request.Url.ToString() + "/n源: " + exception.Source + "/n消息Message: " + exception.Message + "/n堆栈: " + exception.StackTrace;

//ctx.Response.Write(errorInfo);

// --------------------------------------------------

// To let the page finish running we clear the error

// --------------------------------------------------

//ctx.Server.ClearError();

//base.OnError(e);

string LogName = "MyWebError";

if (!System.Diagnostics.EventLog.SourceExists(LogName))

{

System.Diagnostics.EventLog.CreateEventSource(LogName, "App");

}

System.Diagnostics.EventLog el = new System.Diagnostics.EventLog();

el.Source = LogName;

el.WriteEntry(errorInfo, System.Diagnostics.EventLogEntryType.Error);

}

web.config 上修改友好错误页 <customErrors mode="On" defaultRedirect="MyErrorPage.aspx">

</customErrors>
