問題：
I want to be able to figure out what port a particular program is using. 我希望能夠找出特定程序正在使用的端口。 Are there any programs available online or that come with windows that will tell me which processes are using which ports on my computer? 是否有任何在線可用的程序或帶有Windows的程序可以告訴我哪些進程正在使用我的計算機上的哪些端口？
PS - before you downmod this for not being a programming question, I'm looking for the program to test some networking code. PS - 在你因爲不是一個編程問題而下調這個問題之前，我正在尋找測試一些網絡代碼的程序。
