我想在接受或连接的客户端服务器上获取IP地址

不，它不会。我在TcpClient文档中找不到任何东西（fw 1.1）
类可以揭示客户端的IP地址（但我可能在这里错了）。如果
你可以使用Socket类，那么你可以使用RemoteEndPoint属性。

will it give ip address of client
i want to fetch ip address on server of client which is accepted or
connected

No, it won''t. I can''t find anything in TcpClient documentation (fw 1.1)
class that would reveal client''s IP address (but I may be wrong here) . If
you can use Socket class, then you can use RemoteEndPoint property.
