自定义错误页面

2.建立一个页面类(假设叫BasePage),继承于Page，然后你的站点的所有页面都从这个类继承，这样你只要在BasePage类里：override OnInit事件，在里面:
this.Error += new System.EventHandler(this.error());
然后在error()方法里做你的统一的错误处理，这样，所有页的错误处理就一样了。

给你点例子： protected void error(object sender, System.EventArgs e) { string errMsg; Exception currentError = Server.GetLastError(); errMsg = "<h1>Page Error</h1><hr/>An unexpected error has occurred on this page. The system " +"administrators have been notified. Please feel free to contact us with the information " +"surrounding this error.<br/>"+ "The error occurred in: "+Request.Url.ToString()+"<br/>"+ "Error Message: <font class=\"ErrorMessage\">"+ currentError.Message.ToString() + "</font><hr/>"+ "<b>Stack Trace:</b><br/>"+ currentError.ToString(); if ( !(currentError is AppException) ) { // It is not one of ours, so we cannot guarantee that it has been logged // into the event log. LogEvent( currentError.ToString(), EventLogEntryType.Error ); } Response.Write( errMsg ); Server.ClearError(); }
