WebPermission.Intersect Method

Returns the logical intersection of two WebPermission instances.

Namespace: System.Net
Assembly: System (in system.dll)

public override IPermission Intersect (
	IPermission target
)
public IPermission Intersect (
	IPermission target
)
public override function Intersect (
	target : IPermission
) : IPermission
Not applicable.

Parameters

target

The WebPermission to compare with the current instance.

Return Value

A new WebPermission that represents the intersection of the current instance and the target parameter. If the intersection is empty, the method returns a null reference (Nothing in Visual Basic).

Exception typeCondition

ArgumentException

target is not a null reference (Nothing in Visual Basic) or of type WebPermission

Intersect returns a WebPermission that contains those permissions that are common in both target and the current instance.

This method overrides Intersect and is implemented to support the IPermission interface.

The following example shows how to create an instance of WebPermission using the logical intersection of two existing WebPermission instances.


// Create a third WebPermission instance via the logical intersection of the previous
// two WebPermission instances.
WebPermission myWebPermission3 =(WebPermission) myWebPermission1.Intersect(myWebPermission2);

Console.WriteLine("\nAttributes and Values of  the WebPermission instance after the Intersect are:\n");   
Console.WriteLine(myWebPermission3.ToXml().ToString());


// Create a third WebPermission instance via the logical intersection 
// of the previous two WebPermission instances.
WebPermission myWebPermission3 = 
    (WebPermission) myWebPermission1.Intersect(myWebPermission2);

Console.WriteLine("\nAttributes and Values of  the WebPermission " 
    + "instance after the Intersect are:\n");
Console.WriteLine(myWebPermission3.ToXml().ToString());
