An IPermission to intersect with the current permission. It must be of the same type as the current permission.

ExceptionCondition
ArgumentException

target is not an SmtpPermission.

The intersection of two permissions is a permission that describes the state they describe in common. Only a demand that passes both original permissions will pass the intersection.

The following code example creates a permission object that is the intersection of an existing permission with an object that grants full access to SMTP servers.

static SmtpPermission^ IntersectionWithFull(
    SmtpPermission^ permission)
{
    SmtpPermission^ allAccess = 
        gcnew SmtpPermission(PermissionState::Unrestricted);
    return (SmtpPermission^) permission->Intersect(allAccess);
}
