NETFramework provides a System.Net.Socket namespace for socket communication, in which there are several important classes that are commonly used: · Socket class This low-level class is used to manage connections, and webrequest,tcpclient and UdpClient use this class internally. · NetworkStream class This class is derived from the stream, which represents the flow of data from the network · TcpClient class allows TCP con

asp.net|smtp| create asp.net in the System.Web.Mail namespace there is a built-in class that sends emails, but this is only an illusion of CDOSYS. Developers can use an alternative to its SMTP mail service. In this article, I'll show you how to create a full-featured SMTP mail service for asp.net. First, we create a class that inherits the TcpClient class of the namespace System.Net.Sockets. The TcpClient class provides a simple way to connect, send, and receive data streams from the network.

Server:Two threads are created to process client requests. One thread is used to receive the connected Socket and add the Socket to a Queue object; another thread is used to propose the Socket in the Queue for receiving and sending operations. The receiving and sending operations are asynchronous. Client:Create a NetworkStream instance (NetworkStream stream = new Net
