本例介绍怎样建立简单的程序，实现类似于系统ping的功能。通过这个例子，您不仅能够学会如何建立一个类似系统"ping"的程序，更主要的是对.NET环境下进行socket级网络编程有初步的认识。-the cases presented on how to establish a simple procedure, similar to the system to achieve ping function. Through this example, you can learn not only how to establish a similar system "ping" of the procedure, the main yes right.NET environment for socket-level network programming a preliminary understanding.

TCP/IP协议是一个比较复杂的协议集，有很多专业书籍介绍。在此，我仅介绍其与编程密切相关的部分：以太网上TCP/IP协议的分层结构及其报文格式。-TCP/IP protocol is a more complex set of agreements, there are many professional books introduced. Here, I just introduced its programming and closely related to the part : Ethernet TCP/IP protocol to the hierarchical structure and its message format.

为调试设备编写的RS232转以太网通信软件。 均使用异步通信方式，RS232使用API编写，以太网使用Sockte类。程序中使用了两个独立线程，线程间以消息方式传递数据，本程序中包括：RS232异步通信、Sockte异步通信、用户界面线程、线程间通信。-Equipment prepared for debugging RS232 to Ethernet communications software. Only use asynchronous communication mode, RS232 using the API written in Ethernet using Sockte class. The program uses two separate threads, the threads in the message is transmitted data, this program includes: RS232 asynchronous communication, Sockte asynchronous communication, the user interface thread, communication between threads.
