- target
- IPermission
An IPermission to intersect with the current permission. It must be of the same type as the current permission.
Returns
An SmtpPermission that represents the intersection of the current permission and the specified permission. Returns null if the intersection is empty or target is null.

Examples
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);
}
public static SmtpPermission IntersectionWithFull(SmtpPermission permission)
{
SmtpPermission allAccess = new
SmtpPermission(System.Security.Permissions.PermissionState.Unrestricted);
return (SmtpPermission) permission.Intersect(allAccess);
}
Remarks
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.
