UrlIdentityPermission.Intersect(IPermission) Method

Definition

Creates and returns a permission that is the intersection of the current permission and the specified permission.

public:
 override System::Security::IPermission ^ Intersect(System::Security::IPermission ^ target);
public override System.Security.IPermission Intersect (System.Security.IPermission target);
override this.Intersect : System.Security.IPermission -> System.Security.IPermission
Public Overrides Function Intersect (target As IPermission) As IPermission

Parameters

target
IPermission

A permission to intersect with the current permission. It must be of the same type as the current permission.

Returns

A new permission that represents the intersection of the current permission and the specified permission. This new permission is null if the intersection is empty.

Exceptions

The target parameter is not null and is not of the same type as the current permission.

-or-

The Url property is not a valid URL.

Remarks

The intersection of two permissions is a permission that describes access to the URLs they both describe in common. Only a demand that passes both original permissions will pass the intersection. For example, the intersection of a permission that represents access to http://www.fourthcoffee.com/process/grind.htm and a permission that represents access to http://www.fourthcoffee.com/* is a permission that represents access to http://www.fourthcoffee.com/process/grind.htm.

UrlIdentityPermission supports set operations (IsSubsetOf, Intersect, and Union) only when the current permission is equal to the specified permission object or when one of the permissions uses the wildcard operator ("*").
