try catch中用了 Response.Redirect 引发的线程异常终止
altzlo7909的博客

记录一下，提醒自己。 今天写代码的时候，在try 中写了一句Response.Redirect 在catch 把页面重定向到了另外一个地方 本来是想打算，如果没出现异常，就定到页面A，如果异常了就定到页面b，然后发现，尼玛怎么样都去了页面b 本来以为是我try代码块中，访问webService出现了什么异常，单步调试了好久，每次都正常没有错误，但是一到Response....
关于Response.redirect和Response.End出现线程中止异常的处理

在调用response.end的时候有时会报告“线程正被终止”的异常，以下是微软官方的解决办法症状如果使用 Response.End、Response.Redirect 或 Server.Transfer 方法，则出现 ThreadAbortException 异常。 可使用 try-catch 语句捕捉此异常。 原因Response.End 方法停止页的执行，并将该执行变换到应用程序的事件管
