当系统具有多个NIC适配器时如何指定源IP [英] how do I to specify the soure IP when the system has multiple nic adapters

问题描述

byte[] fileNameByte = Encoding.ASCII.GetBytes(e.FullPath);
      byte[] fileData = File.ReadAllBytes(e.FullPath);
      byte[] clientData = new byte[4 + e.Name.Length + fileData.Length];
      byte[] fileNameLen = BitConverter.GetBytes(fileNameByte.Length);
      m_socWorker = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.IP);
      String szIPSelected = "192.168.0.1";
      String szPort = "33333";
      try
      {
          int alPort = System.Convert.ToInt16(szPort, 10);
          System.Net.IPAddress remoteIPAddress = System.Net.IPAddress.Parse(szIPSelected);
          System.Net.IPEndPoint remoteEndPoint = new System.Net.IPEndPoint(remoteIPAddress, alPort);
          m_socWorker.Connect(remoteEndPoint);
      }
      catch (System.Net.Sockets.SocketException se)
      {
          Console.WriteLine(se.Message);
      }

推荐答案

您不知道.根据到目标IP地址的路由选择NIC.

You don''t. The NIC is chosen based on the route to the destination IP Address.
