Source:

DataProtectionPermission.cs

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 the same type as the current permission.

Returns

IPermission

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

ArgumentException

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.
