在C＃中有多少个客户端连接到指定的UDP端口号

Question

如何计算C＃中连接到UDP套接字的客户端数量？

Answer 1

You can use IPGlobalProperties and one of these methods

IPGlobalProperties.GetUdpIPv4Statistics

Provides User Datagram Protocol/Internet Protocol version 4 (UDP/IPv4) statistical data for the local computer.

for ipv6 there is also another function

Answer 2

UDP is a connectionless protocol, so there are no connections to count. IPGlobalProperties.GetUdpIPv4Statistics only gives you the number of listerners on the system, which I don't think is what you are looking for. It would be helpful if you specify what you are trying to do!
