为什么Windows server 2008 R2的系统下asp.net提交表单时会发生如下的错误？
System.Security.CryptographicException，用Windows XP/2003/2008都不会存在这个问题，为什么会跟系统有关系？在网上查了好几个办法都无效，郁闷！！！

你先将提交表单的代码贴出来看下 --------------------编程问答-------------------- 下面的代码在Windows server 2008及以下的服务器版操作系统中都没有问题，就是windows server 2008 R2才发生这个错误，说：System.Security.CryptographicException 系统找不到制定的文件。
