TCPClient vs Socket in C#
提问by
I don't see much use of TCPClient, yet there is a lot of Socket? What is the major difference between them and when would you use each?
我没有看到很多用途TCPClient，但有很多Socket? 它们之间的主要区别是什么？您何时会使用它们？
I understand that .NET Socketis written on top of WINSOCK, and TCPClientis a wrapper over Socketclass. Thus TCPClientis way up the chain, and possibly inefficient. Correct me if I am wrong.
我知道 .NETSocket是在 WINSOCK 之上编写的，并且TCPClient是Socket类的包装器。因此TCPClient是链上的方式，并且可能效率低下。如果我错了，请纠正我。

The use of TcpClient and TcpListener just means a few less lines of code. As you say it's just a wrapper over the Socket class so there is no performance difference between them it's purely a style choice.
使用 TcpClient 和 TcpListener 只是意味着少了几行代码。正如您所说，它只是 Socket 类的包装器，因此它们之间没有性能差异，这纯粹是一种风格选择。
Update:Since this answer was posted the .Net source code has become available. It does indeed show that TcpClientis a very light wrapper over the Socketclass which is itself a wrapper on top of the native WinSock2 API*.
更新：自从发布此答案后，.Net 源代码已可用。它确实表明TcpClient是Socket类的一个非常轻量级的包装器，它本身就是原生WinSock2 API*之上的一个包装器。
- On Windows. Will be different for .Net Standard/Core etc. on other platforms.
- 在 Windows 上。其他平台上的 .Net Standard/Core 等会有所不同。

Also, you can access the socket directly from the TCPClientobject, it's under the property Client- so there is no performance difference.
此外，您可以直接从TCPClient对象访问套接字，它位于属性下Client- 因此没有性能差异。
