我从来没有这样做过。看起来很复杂。

首先，阅读自定义 ASMX 的方法客户端代理了解重写代理类的GetWebRequest对象的基本技术。

您需要重写GetWebRequest，以便可以获取用于发出请求的ServicePoint。您将设置 BindIPEndPoint 属性指向指向您的方法的委托，该方法将返回正确的 IP 地址。

public partial class Service1
{
    protected override WebRequest GetWebRequest(Uri uri)
    {
        HttpWebRequest request = (HttpWebRequest) base.GetWebRequest(uri);
        request.ServicePoint.BindIPEndPointDelegate = ReturnSpecificIPAddress;
        return request;
    }

    private IPEndPoint BindIPEndPoint(
        ServicePoint servicePoint,
        IPEndPoint remoteEndPoint,
        int retryCount)
    {
        return new IPEndPoint(IPAddress.Parse("10.0.0.1"), 80);
    }
}

I've never done this. It looks complicated.

First, read Ways to Customize your ASMX Client Proxy to learn the basic technique of overriding the GetWebRequest object of your proxy class.

You will need to override GetWebRequest so that you can grab the ServicePoint being used to make the request. You will set the BindIPEndPoint property to a delegate pointing to a method of yours which will return the correct IP Address.

public partial class Service1
{
    protected override WebRequest GetWebRequest(Uri uri)
    {
        HttpWebRequest request = (HttpWebRequest) base.GetWebRequest(uri);
        request.ServicePoint.BindIPEndPointDelegate = ReturnSpecificIPAddress;
        return request;
    }

    private IPEndPoint BindIPEndPoint(
        ServicePoint servicePoint,
        IPEndPoint remoteEndPoint,
        int retryCount)
    {
        return new IPEndPoint(IPAddress.Parse("10.0.0.1"), 80);
    }
}

在 WCF 中，当您创建 ChannelFactory 时，您可以指定您的端点（或您希望连接的 IP 地址）。

 Dim factory As ChannelFactory(Of IChatServiceChannel)
 factory = New DuplexChannelFactory(Of IChatServiceChannel)(callbackObject, binding, endpoint)
 Dim Channel = factory.CreateChannel()

您可以通过指定不同的端点来连接到任意多个不同的 IP。

In WCF when you create your ChannelFactory you can specify your endpoint (or IP address to which you wish to connect).

 Dim factory As ChannelFactory(Of IChatServiceChannel)
 factory = New DuplexChannelFactory(Of IChatServiceChannel)(callbackObject, binding, endpoint)
 Dim Channel = factory.CreateChannel()

You can connect to as many different IPs as you want like this by specifying different endpoints.
