Is Response.End() considered harmful?

Question

This KB Article says that ASP.NET\'s Response.End() aborts a thread.

Reflector shows that it looks like this:

public void End()
{
            


        

Answer 1

I've never considered using Response.End() to control program flow.

However Response.End() can be useful for example when serving files to a user.

You have written the file to the response and you don't want anything else being added to the response as it may corrupt your file.
