- target
- IPermission
A permission to intersect with the current permission. It must be 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
target is not null and does not specify a permission of the same type as the current permission.
Examples
The following code example shows the use of the Intersect method. This code example is part of a larger example provided for the DataProtectionPermission class.
Console::WriteLine( "Creating the intersection of the second and "
"first permissions." );
sp4 = dynamic_cast<DataProtectionPermission^>(sp2->Intersect( sp1 ));
Console::WriteLine( "The value of the Flags property is: {0}", sp4->Flags );
Console.WriteLine("Creating the intersection of the second and " +
"first permissions.");
sp4 = (DataProtectionPermission)sp2.Intersect(sp1);
Console.WriteLine("The value of the Flags property is: " +
sp4.Flags.ToString());
Console.WriteLine("Creating the intersection of the second and " + "first permissions.")
sp4 = CType(sp2.Intersect(sp1), DataProtectionPermission)
Console.WriteLine("The value of the Flags property is: " + sp4.Flags.ToString())
Remarks
The intersection of two permissions is a permission that describes the set of operations they both describe in common. Only a demand that passes both individual permissions will pass the intersection.
