Public Function RemovePermission (permClass As Type) As IPermission
Public Overridable Function RemovePermission (permClass As Type) As IPermission
Parameters
- permClass
- Type
The type of permission to delete.
Returns
The permission removed from the set.
Exceptions
The method is called from a ReadOnlyPermissionSet.
Examples
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())
Remarks
Important
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));
Notes to Inheritors
When you inherit from PermissionSet, you can change the behavior of the RemovePermission(Type) method by overriding the RemovePermissionImpl(Type) method.
