Visual C#得到局域网计算机列表，也就是获取局域网内的所有在线的主机名称列表，请确保您的电脑在网络中，要不然程序获取时候可能要假死，需要强制结束任务。(Visual C# to get a LAN computer list, which is to obtain a list of all the online host names within the LAN, make sure your computer is on the network, or else the program when you may want to get suspended animation, you need to force the end of the task.)

在多跳无线网络进行TDMA方式接入时候，时间是被划分为互不重叠的时隙，边长或定长帧在时隙中进行传输。 当面向节点时候，一个节点可以得到一个或者多个时隙，节点可以利用这些时隙向任何一条链路发送报文到邻居节点。 面向链路分配时候，则是某条单向链路分得一个或多个时隙，在这些时隙中，报文发送是单向的。(Time is divided into non-overlapping slots when multi-hop wireless networks are accessed by TDMA mode. Side-length or fixed-length frames are transmitted in slots. When facing a node, a node can get one or more slots, which can be used by the node to send messages to any link to its neighbors. For link allocation, a one-way link is allocated one or more slots, in which message transmission is one-way.)
