C# HttpWebRequest在启用多个网络适配器时超时

在我的Win7 PC上，我有两个用于VMWare server的虚拟网络适配器。 启用这些适配器后，HttpWebRequest超时。我真的应该告诉它绑定到哪个适配器吗

            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url.AbsoluteUri + "etc.txt");
            request.Timeout = 2000;

            using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
            {
                using (StreamReader reader = new StreamReader(response.GetResponseStream()))
                {
                    return reader.ReadToEnd();
                }
            }

我猜这是一个常见的问题。有人有标准的方法来处理这个问题吗？我不能真正提示用户输入界面，因为他们不是技术人员。Rohit的答案是显示如何设置ServicePoint的良好开端。

Tim，如果你看到超时，那是因为你的新适配器有URL的路由，它们没有到达目的地

public delegate IPEndPoint BindIPEndPoint(ServicePoint servicePoint, IPEndPoint remoteEndPoint, int retryCount);

你可以把它当作

private IPEndPoint BindIPEndPointCallback(ServicePoint servicePoint,IPEndPoint remoteEndPoint, int retryCount)
{
    if(retryCount < 3)
        return new IPEndPoint(IPAddress.Parse("192.168.10.60"), 0); 
    else
        return new IPEndPoint(IPAddress.Any, 0);
}

下面是它的答案。这能很好地尝试所有的适配器吗

    private IPEndPoint BindIPEndPointCallback(ServicePoint servicePoint, IPEndPoint remoteEndPoint, int retryCount)
    {
        List<IPEndPoint> endPoints = new List<IPEndPoint>();

        foreach (NetworkInterface netinface in NetworkInterface.GetAllNetworkInterfaces())
        {
            foreach (IPAddressInformation unicast in netinface.GetIPProperties().UnicastAddresses)
            {
                if(unicast.Address.AddressFamily == System.Net.Sockets.AddressFamily.InterNetwork)
                    endPoints.Add(new IPEndPoint(unicast.Address, 80));
            }
        }

        if (retryCount > endPoints.Count - 1)
            return new IPEndPoint(IPAddress.Any, 80);
        else
            return endPoints[retryCount];
    }

private-IPEndPoint-BindIPEndPointCallback（ServicePoint-ServicePoint、IPEndPoint-remoteEndPoint、int-retryCount）
{
列表端点=新列表（）；
foreach（NetworkInterface.GetAllNetworkInterfaces（）中的NetworkInterface netinface）
{
foreach（netinface.GetIPProperties（）.UnicastAddress中的IPAddressInformation单播）
{
if（unicast.Address.AddressFamily==System.Net.Sockets.AddressFamily.InterNetwork）
Add（新的IPEndPoint（unicast.Address，80））；
}
}
if（retryCount>endPoints.Count-1）
返回新的IPEndPoint（IPAddress.Any，80）；
其他的
返回端点[retryCount]；
}

    private IPEndPoint BindIPEndPointCallback(ServicePoint servicePoint, IPEndPoint remoteEndPoint, int retryCount)
    {
        List<IPEndPoint> endPoints = new List<IPEndPoint>();

        foreach (NetworkInterface netinface in NetworkInterface.GetAllNetworkInterfaces())
        {
            foreach (IPAddressInformation unicast in netinface.GetIPProperties().UnicastAddresses)
            {
                if(unicast.Address.AddressFamily == System.Net.Sockets.AddressFamily.InterNetwork)
                    endPoints.Add(new IPEndPoint(unicast.Address, 80));
            }
        }

        if (retryCount > endPoints.Count - 1)
            return new IPEndPoint(IPAddress.Any, 80);
        else
            return endPoints[retryCount];
    }
