[求助]类的权限控制

[wyhao]

如何控制引用的一个外部类的权限？比如禁止操作文件访问网络之类的？

using System.Security;
using System.Security.Permissions;


        [FileIOPermission(SecurityAction.Deny, All="C:\\")]
        void FirstMetho()
        {
            // all read write upon files in c: drive will be denied
            // ...
            classInTheDll.ReadAllText("c:\\temp\\ufo.cs");           // denied
            // ...
        }

       void SecondMethod()
       {
           WebPermission myWebPermission = 
                new WebPermission(NetworkAccess.Connect,"http://abc.com");

           myWebPermission.Deny();

           // access to abc.com will be denied
           // 
           classInTheDll.SomeFunction();

           CodeAccessPermission.RevertDeny(); 
       }
