Disabling Delayed Ack in TCP using TcpClient class or Socket class of .Net Framework

Question

Dear friend, I am developing an application using .Net Framework class TcpClient that sends data over TCP to a listener. I want to disable delayed ack using the TcpClient class members or Socket members. I can use SetSocketOption() of Socket class but I do not know which option to set. There is no mention of this particular thing in SocketOptionName. If anybody has a clue, please let me know on [email protected]
