asp.net中当服务器出错时显示指定的错误页

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. }
