C＃通过TCP发送信息

Question

I'm still learning C#, so don't yell at me for not doing anything right. Also, i know I should probably be using WPF, but in my current condition I need to use winForms.

Client:

public void sendData(String dataIn)
{
    String IP = textBox1.Text;
    String Port = textBox2.Text;
    net.Send(dataIn, IP, Port);
}

Server:

public string listenForData()
{
    String dataOut = net.Listen();
    return dataOut;
}

How do I create a method that takes a string and sends it to a server application. I know it has something to do with TCP sockets. I've looked but I don't understand any tutorials or videos i've found.

Thanks in advance, Noah.

You could try looking into the TCP Client Class.

https://msdn.microsoft.com/en-us/library/system.net.sockets.tcpclient(v=vs.110).aspx

You can get the stream from tcp client and use that to write your string to, by converting the string to a byte[] first.

// Setup TCP Client with valid values first. Make Client and stream private or public variables/properties.

TCPClient client = new TCPClient(IP, (int)Port); // Following validation on Port & IP
NetworkStream stream = client.GetStream();

private void SendDataToServer(String dataIn) {
     Byte[] StringToSend = Encoding.UTF8.GetBytes(dataIn);
     stream.Write(StringToSend, 0, StringToSend.Length);
}
