注解

SecurityException当调用方没有访问资源所需的权限时，将引发异常。 以下示例实例化一个 PermissionSet 对象，该对象包含一个 UIPermission 对象，该对象允许访问 UI 对象和剪贴板，以及一个 RegistryPermission 用于阻止注册表访问的对象。 PermissionSet.PermitOnly调用 方法意味着无论分配给调用方的权限如何，都将应用这些权限。 因此，尝试创建注册表项会 SecurityException引发 。

public class Example
{
   public static void Main()
   {
      PermissionSet perms = new PermissionSet(null);
      perms.AddPermission(new UIPermission(PermissionState.Unrestricted));
      perms.AddPermission(new RegistryPermission(PermissionState.None));
      perms.PermitOnly();
      
      try {
          RegistryKey key = Registry.CurrentUser.CreateSubKey("MyCompany\\Applications");
          Console.WriteLine("Registry key: {0}", key.Name);
      }
      catch (SecurityException e) {
         Console.WriteLine("Security Exception:\n\n{0}", e.Message);      
      }
   }
}
// The example displays the following output:
//    Security Exception:
//    
//    Request for the permission of type 'System.Security.Permissions.RegistryPermission, 
//    mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
