为什么 Response.Redirect 会导致 System.Threading.ThreadAbortException? [英] Why Response.Redirect causes System.Threading.ThreadAbortException?

问题描述

当我使用 Response.Redirect(...) 将表单重定向到新页面时，出现错误:

When I use Response.Redirect(...) to redirect my form to a new page I get the error:

在 mscorlib.dll 中发生了System.Threading.ThreadAbortException"类型的第一次机会异常
mscorlib.dll 中出现System.Threading.ThreadAbortException"类型的异常，但未在用户代码中处理

A first chance exception of type 'System.Threading.ThreadAbortException' occurred in mscorlib.dll
An exception of type 'System.Threading.ThreadAbortException' occurred in mscorlib.dll but was not handled in user code

我对此的理解是，错误是由网络服务器中止调用 response.redirect 的页面的其余部分引起的.

My understanding of this is that the error is being caused by the webserver aborting the remainder of the page the response.redirect was called on.

我知道我可以向 Response.Redirect 添加第二个参数，称为 endResponse.如果我将 endResponse 设置为 True 我仍然会收到错误但如果我将它设置为 False 那么我不会.我很确定这意味着网络服务器正在运行我重定向的页面的其余部分.至少可以说这似乎是低效的.有一个更好的方法吗?Response.Redirect 以外的东西，或者有没有办法强制旧页面停止加载，我不会收到 ThreadAbortException ?

I know I can add a second parameter to Response.Redirect that is called endResponse. If I set endResponse to True I still get the error but if I set it to False then I do not. I am pretty sure though that that means the webserver is running the rest of the page I redirected away from. Which would seem to be inefficient to say the least. Is there a better way to do this? Something other than Response.Redirect or is there a way to force the old page to stop loading where I will not get a ThreadAbortException?

推荐答案

正确的模式是使用 endResponse=false 调用 Redirect 重载，并调用告诉 IIS 管道它应该直接前进到 EndRequest 阶段后返回控制:

The correct pattern is to call the Redirect overload with endResponse=false and make a call to tell the IIS pipeline that it should advance directly to the EndRequest stage once you return control:

Response.Redirect(url, false);
Context.ApplicationInstance.CompleteRequest();
