c# - .net 本地程序集加载因 CAS 策略失败

Question

我们收到以下程序集加载错误。该程序集从本地路径“C:\Program Files\ASWorx Products\ASWorx\Bin\”加载。问题不在于旧版本的二进制文件。当我们通过电子邮件发送新的二进制文件时，问题就出现了。build设置未更改。我们怎样才能纠正这个问题？问题出现在Win7 32位机

File name: 'file:///C:\Program Files\ASWorx Products\ASWorx\Bin\ASConnexDI.dll' ---> System.NotSupportedException: An attempt was made to load an assembly from a network location which would have caused the assembly to be sandboxed in previous versions of the .NET Framework. This release of the .NET Framework does not enable CAS policy by default, so this load may be dangerous. If this load is not intended to sandbox the assembly, please enable the loadFromRemoteSources switch. See http://go.microsoft.com/fwlink/?LinkId=155569 for more information.

Answer 1

来自link in the error message :

If an application has been copied from the web, it is flagged by Windows as being a web application, even if it resides on the local computer. You can change that designation by changing the file properties, or you can use the element to grant the assembly full trust. As an alternative, you can use the UnsafeLoadFrom method to load a local assembly that the operating system has flagged as having been loaded from the web.
