我的output.aspx页面有时出现以下错误:
异常详细信息:System.Web.HttpException:请求超时。
来源错误:
在执行当前Web请求期间生成了未处理的异常。可以使用下面的异常堆栈跟踪来识别有关异常的起源和位置的信息。
堆栈追踪:
[HttpException(0x80004005):请求超时。]
捕获此异常是一个好主意吗?我在哪里这样做,因为我的output.aspx.cs有一个Page_Load,该函数调用RunTable()。我应该在函数内容周围放置一个try catch块吗?

在应用程序级别捕获异常
void Application_Error(object sender, EventArgs e)
{
// Code that runs when an unhandled error occurs
// Get the exception object.
Exception exc = Server.GetLastError();
// Handle HTTP errors
if (exc.GetType() == typeof(HttpException))
{
// The Complete Error Handling Example generates
// some errors using URLs with "NoCatch" in them;
// ignore these here to simulate what would happen
// if a global.asax handler were not implemented.
if (exc.Message.Contains("NoCatch") || exc.Message.Contains("maxUrlLength"))
return;
//Redirect HTTP errors to HttpError page
Server.Transfer("HttpErrorPage.aspx");
}
// For other kinds of errors give the user some information
// but stay on the default page
Response.Write("<h2>Global Page Error</h2>\n");
Response.Write(
"<p>" + exc.Message + "</p>\n");
Response.Write("Return to the <a href='Default.aspx'>" +
"Default Page</a>\n");
// Log the exception and notify system operators
ExceptionUtility.LogException(exc, "DefaultPage");
ExceptionUtility.NotifySystemOps(exc);
// Clear the error from the server
Server.ClearError();
}
