回答1:

Your Response.End() is most likely what is causing that. It is because it is telling ASP.NET that the request is over.

What is the stack trace from the Exception, where does .NET think the exception is being thrown from?

回答2:

It seems that the file is big so the IIS is killing the thread, you should change this in the web.config:

<httpRuntime 
    maxRequestLength="1048576"
    executionTimeout="3600"
  />

maxRequestLength is in bytes

executionTimeout is in seconds

You sure that doesn't happen in other code not shown ? usually you get that with when you redirect while inside a try-catch

回答4:

The issue is that you're calling Response.End() before Response.Flush(). Swap the order of those statements and the issue will go away.
