The type of permission to delete.
The permission removed from the set.
The method is called from a ReadOnlyPermissionSet.
The following code example shows the use of the RemovePermission method to remove a FileIOPermission from a permission set. This code example is part of a larger example provided for the PermissionSet class.
// Remove FileIOPermission from the permission set.
ps5->RemovePermission( FileIOPermission::typeid );
Console::WriteLine( "The last permission set after removing FileIOPermission = {0}", ps5 );
// Remove FileIOPermission from the permission set.
ps5.RemovePermission(typeof(FileIOPermission));
Console.WriteLine("The last permission set after removing FileIOPermission = "
+ ps5.ToString());
' Remove FileIOPermission from the permission set.
ps5.RemovePermission(GetType(FileIOPermission))
Console.WriteLine("The last permission set after removing FileIOPermission = " & ps5.ToString())
중요
You cannot remove permissions from an unrestricted permission set. The permission set remains unrestricted after you attempt to remove the permission, and an exception is not thrown.
The following C# code attempts to remove the FileIOPermission from the FullTrust
permission set, but the permission is not removed.
PolicyLevel myPol = PolicyLevel.CreateAppDomainLevel();
PermissionSet myPermSet = myPol.GetNamedPermissionSet("FullTrust");
myPermSet.RemovePermission(typeof(FileIOPermission));
When you inherit from PermissionSet, you can change the behavior of the RemovePermission(Type) method by overriding the RemovePermissionImpl(Type) method.
