通过 TCP 在 C# 中发送数据包？

Question

我将尝试在下面解释我的问题，我已经尝试在谷歌上搜索答案，但首先，我真的不知道我应该在谷歌上搜索什么，我还没有找到任何对我有意义的东西，我想知道如果有人能解释一下？非常感谢。

你好。我正在尝试使用 TCP 发送一个简单的网络数据包，我很容易使用 UDP 完成它，因为使用 UDP 真的很容易，我想知道是否有人可以帮助我在 TCP 中做同样的事情？我尝试使用 TcpClient，但它没有与 UDP 相同的 Send 方法？

public void OnUdp()
{
    var client = new UdpClient(Host, Port);
    client.Send(rubbish, rubbish.Length);
}

这是https://msdn.microsoft.com/en-us/library/system.net.sockets.tcpclient.aspx的例子

static void Connect(String server, String message) 
{
  try 
  {
    // Create a TcpClient.
    // Note, for this client to work you need to have a TcpServer 
    // connected to the same address as specified by the server, port
    // combination.
    Int32 port = 13000;
    TcpClient client = new TcpClient(server, port);

    // Translate the passed message into ASCII and store it as a Byte array.
    Byte[] data = System.Text.Encoding.ASCII.GetBytes(message);         

    // Get a client stream for reading and writing.
   //  Stream stream = client.GetStream();

    NetworkStream stream = client.GetStream();

    // Send the message to the connected TcpServer. 
    stream.Write(data, 0, data.Length);

    Console.WriteLine("Sent: {0}", message);         

    // Receive the TcpServer.response.

    // Buffer to store the response bytes.
    data = new Byte[256];

    // String to store the response ASCII representation.
    String responseData = String.Empty;

    // Read the first batch of the TcpServer response bytes.
    Int32 bytes = stream.Read(data, 0, data.Length);
    responseData = System.Text.Encoding.ASCII.GetString(data, 0, bytes);
    Console.WriteLine("Received: {0}", responseData);         

    // Close everything.
    stream.Close();         
    client.Close();         
  } 
  catch (ArgumentNullException e) 
  {
    Console.WriteLine("ArgumentNullException: {0}", e);
  } 
  catch (SocketException e) 
  {
    Console.WriteLine("SocketException: {0}", e);
  }

  Console.WriteLine("\n Press Enter to continue...");
  Console.Read();
}
