ResourcePermissionBase.IsSubsetOf(IPermission) Method

Definition

Namespace:

System.Security.Permissions

Assembly:

System.Security.Permissions.dll

Source:

ResourcePermissionBase.cs

Determines whether the current permission object is a subset of the specified permission.

public:
 override bool IsSubsetOf(System::Security::IPermission ^ target);

public override bool IsSubsetOf (System.Security.IPermission target);

override this.IsSubsetOf : System.Security.IPermission -> bool

Public Overrides Function IsSubsetOf (target As IPermission) As Boolean

Parameters

target

IPermission

A permission object that is to be tested for the subset relationship.

Returns

Boolean

true if the current permission object is a subset of the specified permission object; otherwise, false.

Remarks

The current permission object is a subset of the specified permission object if the current permission object specifies a set of operations that is wholly contained by the specified permission object. For example, a permission that represents access to C:\Example.txt is a subset of a permission that represents access to C:\. If this method returns true, the current permission object represents no more access to the protected resource than does the specified permission object.

This method always returns false when the specified permission object is of a different type than that of the current permission object.
