This article describes the basic concepts of Network Programming Based on socket, including TCP protocol, socket, and two basic operations: listening port and remote server connection. TCP isConnection-orientedIt means two remote hosts (or processes), because in fact remote communication is the communication between processes, while the process is running

This is a creation in Article, where the information may have evolved or changed. In the previous article Go Socket programming Practice: TCP Server and client implementation, we implemented an echo server, and also implemented a client to access the server.This article explains how to implement a UDP server and client.The protocol we're using this time is RFC 868,This protocol provides a site-independent,

NET does not allow cross-thread a

[. NET object-oriented programming in depth] (8) understanding. NET Core 1, overview . NET has been performing well on the Windows platform for over 14 years, but "cross-platform, open source" is its pain point, starting in 16. NET core will usher in the true meaning of.

1. After the successful service listen, the system will automatically receive client requests. Mans Listen: There is a section of The behavior of the backlog argument on TCP sockets changed with Linux2.2. Now it specifies the queue length for completely establishedSockets waiting to be accepted, instead of the number of incompleteConnection requests. The maximum length of the queue for incompleteSockets can be set Using/proc/sys/net/ipv4/tcp_max_s

The ◇networkstream class specializes in providing the underlying data flow for network access. He implements the standard. NET Framework streaming mechanism for sending and receiving data over a network socket. Supports synchronous and asynchronous access to network data streams.In the ◇.net framework, the NetworkStream stream supports two operations.◇1) write to

Overview ADO. NET provides us with powerful database development capabilities. Multiple built-in objects provide different options for our database programming. However, when we allow flexible selection, many beginners are also confused. Should I use datareader or dataadapter? I only want to read a small amount of data. Do I have to fill the entire dataset with fill? Why can't datareader provide a data upd
