您好b $ b

请检查您是否已授予aspnet用户写入/修改上传文件保存所需位置的权限。如果没有提供这些权限。右键单击要提供权限的文件夹，转到属性/安全设置，然后向用户提供权限。



如果仍然无效，那么我就是害怕它是CAS（代码访问安全性）级别检查，其中您的程序集未被授予权限。看看这个 http://social.msdn.microsoft .com / forums / en-US / asmxandxml / thread / b1db5b9f-50a4-4a21-aba1-afeb30957efd [ ^ ]

Hi
Please check whether you have given permissions to aspnet user to write/modify the desired location where your uploaded file gets save. If not do provide these permissions. Right click the folder you want to provide permissions to go to Properties/Security settings and then provide the permissions to the user.

If it still does not work then I am afraid it is CAS (code access security) level check wherein your assembly is not granted the permissions. check this out http://social.msdn.microsoft.com/forums/en-US/asmxandxml/thread/b1db5b9f-50a4-4a21-aba1-afeb30957efd[^]


Hope it solves your problem
