Hello

When using WebClient to send and/or receive data, how can I pass an EndPoint instance to the WebClient to connect via the specified IP and port?

Possible?

Thanks.

    @StewartBW , Welcome to Microsoft Q&A，in .NET, WebClient doesn't directly support connecting via a specific IP address and port. If you need to connect to a specific IP address and port, you typically use other classes like HttpWebRequest.

    Here is a code example you could refer to:

        Sub Main()
        Dim request As HttpWebRequest = CType(WebRequest.Create("http://MyServer"), HttpWebRequest)
        request.ServicePoint.BindIPEndPointDelegate = New BindIPEndPoint(AddressOf BindIPEndPointCallback)
        Dim response As HttpWebResponse = CType(request.GetResponse(), HttpWebResponse)
    End Sub
    Public Function BindIPEndPointCallback(ByVal servicePoint As ServicePoint, ByVal remoteEndPoint As IPEndPoint, ByVal retryCount As Integer) As IPEndPoint
        Console.WriteLine("BindIPEndpoint called")
        Return New IPEndPoint(IPAddress.Any, 5000)
    End Function

    Best Regards,

    Jack
