	IPermission^ target
) override

public IPermission Intersect (
	IPermission target
)

	target : IPermission
) : IPermission

XAML

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).

Exceptions

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

Remarks

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.

Example

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

C++

// 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() );

// 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());
