我不知道是否充分信任模式能够解决您的问题，因为错误似乎是从C ++，要么某种权限的未来在文件系统级丢失或文件本身缺少

I am not sure if giving full trust mode will resolve your issue since error seems to be coming from C++ and either some kind of permission at file system level is missing or the file itself is missing.

在任何情况下，回答你的问题，宥可以使用web.config中设置完全信任模式，增加以下部分，你的web.config，

In any case, to answer your question, yuo can set full trust mode using web.config, add following section to your web.config,

<system.web>
 <securityPolicy>
   <trustLevel name="Full" policyFile="internal"/>
 </securityPolicy>
</system.web>
