有时我的output.aspx页面中出现以下错误:


  异常详细信息:System.Web.HttpException:请求超时。
  
  源错误:
  
  当前Web请求的执行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标识有关异常的来源和位置的信息。
  
  堆栈跟踪:
  
  [HttpException(0x80004005):请求超时。


捕获此异常是个好主意吗?我的输出位置在哪里,因为output.aspx.cs具有Page_Load,并且该函数调用RunTable()。我是否应该在该函数内容周围放置try catch块?

最佳答案

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();
}
