Getting Thread Abort Exception while using Response.Redirect()
提问by Sai Avinash
I wrote the following piece of code in a page which is under Update Panel.
我在更新面板下的页面中编写了以下代码。
protected void myGrid_RowCommand(object sender, GridViewCommandEventArgs e)
{
try
{
if (e.CommandName =="EditNames")
{
long lSelectedName = Convert.ToInt64(e.CommandArgument);
Session["SelectedItem"] = lSelectedName;
Response.Redirect("EditItem.aspx");
}
else if (e.CommandName =="DeleteNames")
{
long lSelectedName = Convert.ToInt64(e.CommandArgument);
ValidName.DeleteItem(lSelectedName);
ScriptManager.RegisterStartupScript(this, GetType(), "Key", "alert('Name deleted sucessfully')", true);
}
}
catch (System.Threading.ThreadAbortException)
{
}
catch (Exception ex)
{
Error handling code...
}
}
Here, I am getting a Thread Abort Exception while redirecting. However, I resolved it by using an error handler System.Threading.ThreadAbortException.
在这里，我在重定向时收到线程中止异常。但是，我通过使用错误处理程序解决了它System.Threading.ThreadAbortException。
But I am unsure why that error came while redirecting. Even though I solved this problem, I would like to know is there any mistake in the way I am coding or is there any way to stop the error firing at all.
但我不确定为什么在重定向时会出现该错误。即使我解决了这个问题，我也想知道我编码的方式是否有任何错误，或者有什么方法可以阻止错误触发。

Note that the page is under AJAX UPDATE PANEL.
请注意，该页面位于 AJAX 更新面板下。

No mistake, you've done well.
没有错，你做得很好。
This error is expected. It's thrown because the server thread is in fact aborted when redirecting. From the MSDN documentation:
这个错误是意料之中的。它被抛出是因为服务器线程实际上在重定向时中止了。从MSDN 文档：
If you specify true for the endResponse parameter, this method calls the End method for the original request, which throws a ThreadAbortException exception when it completes.
如果为 endResponse 参数指定 true，则此方法将调用原始请求的 End 方法，该方法在完成时抛出 ThreadAbortException 异常。
and the documentation for the overload you're using:
Redirect calls End which throws a ThreadAbortException exception upon completion.
重定向调用 End ，它在完成时抛出 ThreadAbortException 异常。

Please read this article - http://blogs.msdn.com/b/tmarq/archive/2009/06/25/correct-use-of-system-web-httpresponse-redirect.aspx
Instead of ending the request, it is a good practice to bypass the request execution pipeline by calling the Context.ApplicationInstance.CompleteRequest().
最好不要结束请求，而是通过调用Context.ApplicationInstance.CompleteRequest().
So your code would look something like this:
所以你的代码看起来像这样：
Response.Redirect("TargetPage", false); //write redirect
Context.ApplicationInstance.CompleteRequest(); // end response
回答by user3098514
It is enough to mention false in the redirect method, like, Response.Redirect("TargetPage", false);
在重定向方法中提及 false 就足够了，例如 Response.Redirect("TargetPage", false);
回答by Mahdi Esmailoghli
This is happening because you are redirecting inside of your try/catch block. Don't do this.
发生这种情况是因为您在 try/catch 块内重定向。不要这样做。
