asp.net的Server.Transfer（）异常 [英] asp.net Server.Transfer() exception

问题描述

为什么我收到异常当执行Server.Transfer的（）...

  Server.Transfer的（@？〜/学生/ StudentSendMail.aspx用户名=+用户名）;{无法评估前pression因为code优化或本机框上调用堆栈的顶部。}
 

解决方案

这奇怪的错误消息的一个原因是try-catch块内执行Server.Transfer的。有一对夫妇的方式来处理：

1）添加第二个参数设置为false这样的：

  Server.Transfer的（@？〜/学生/ StudentSendMail.aspx用户名=+用户名，假的）;
 

2）捕捉类型的异常 System.Threading.ThreadAbortException 键，所以异常被忽略，什么也不做的catch块

3）移动的Server.Transfer到最后块

Why am I getting the exception While executing the Server.Transfer()...

Server.Transfer(@"~/Student/StudentSendMail.aspx?username=" + username);

{Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack.}

解决方案

One cause of this strange error message is performing a Server.Transfer inside of a try-catch block. There are a couple of ways to handle that:

1) Add a second argument set to false like this:

Server.Transfer(@"~/Student/StudentSendMail.aspx?username=" + username, false);

2) Catch the Exception of type System.Threading.ThreadAbortException and do nothing in the catch block so the exception is ignored

3) Move the Server.Transfer to the Finally block
