远程服务器连接检查 [英] Remote server connection check

问题描述

HI，

我正在VS .NET 2008下用C#开发应用程序.为此，我必须建立与远程服务器的连接，并且必须将文件从服务器下载到我的系统.

但是我希望在建立新连接之前，可能已经在其他模块等中建立了连接.我想检查是否已建立连接，它会告诉我连接已建立"的状态，以便我可以使用以前的连接进行下载.

在此先感谢.

问候

Nauman

I am developing an application in C# under VS .NET 2008. For this I have to establish a connection to the remote server and have to download the files from server to my system.

But I want that before making a new connection, it is possible that connection is already established in other modules etc. I want to check that if connection is already established it tell me the status that "connection is already established", so that I can use previous connection for downloading.

Thanks in Advance.

Regards

Nauman

推荐答案

如何...

How about...

using System.Net.NetworkInformation;

IPGlobalProperties properties = IPGlobalProperties.GetIPGlobalProperties();
TcpConnectionInformation[] tcpInfoList = properties.GetActiveTcpConnections();

foreach (TcpConnectionInformation info in tcpInfoList)
{
    // Code to check on the info object for your remote server details
}

出于上述需要，您需要使用连接池.
