XamlLoadPermission.IsSubsetOf(IPermission) Method

Definition

Namespace:

System.Xaml.Permissions

Assembly:

System.Security.Permissions.dll

Source:

XamlLoadPermission.cs

Determines whether the current XamlLoadPermission 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 that is to be tested for the subset relationship. Can be null.

Returns

Boolean

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

Exceptions

ArgumentException

target is not null or is not a XamlLoadPermission.

Remarks

For union, intersect, and subset logic, IsUnrestricted is checked first, and might return a result based solely on that check. Next, AllowedAccess is checked.

If target is null and the current XamlLoadPermission is both IsUnrestricted false and has an empty AllowedAccess list, this method returns true.
