WebPermission.Intersect Method

Returns the logical intersection of two WebPermission instances.

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

'Declaration
Public Overrides Function Intersect ( _
	target As IPermission _
) As IPermission
'Usage
Dim instance As WebPermission 
Dim target As IPermission 
Dim returnValue As IPermission 

returnValue = instance.Intersect(target)

Parameters

target
Type: System.Security.IPermission

The WebPermission to compare with the current instance.

Return Value

Type: System.Security.IPermission
A new WebPermission that represents the intersection of the current instance and the target parameter. If the intersection is empty, the method returns Nothing.

Implements

IPermission.Intersect(IPermission)

ExceptionCondition
ArgumentException

target is not Nothing 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. 
   Dim myWebPermission3 As WebPermission = CType(myWebPermission1.Intersect(myWebPermission2), WebPermission)

   Console.WriteLine(ControlChars.Cr + "Attributes and Values of  the WebPermission instance after the Intersect are:" + ControlChars.Cr)
   Console.WriteLine(myWebPermission3.ToXml().ToString())
End Sub 'CreateIntersect
// Create a third WebPermission instance via the logical intersection of the previous
// two WebPermission instances.
WebPermission* myWebPermission3 =dynamic_cast<WebPermission*> (myWebPermission1->Intersect(myWebPermission2));

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