Question

我想从我的服务器上发送和接收一些数据,但我不知道如何这样做。

Basically I want to: Send: "some string" To: IP: 10.100.200.1 Port: 30000

Receive/read the response

难道有人会给我一些基本例子,或者把我说到简单的(工作)辅导?

Answer 1

简明扼要 TcpClient sent a text string and received a text string.

using System;
using System.IO;
using System.Net;
using System.Text;
using System.Net.Sockets;

public class SimpleTcpClient {

    public static void Main() {

        TcpClient tcpclnt = new TcpClient();            
        tcpclnt.Connect("10.100.200.1",30000);

        String textToSend = "HelloWorld!";
        Stream stm = tcpclnt.GetStream();

        ASCIIEncoding asen = new ASCIIEncoding();
        byte[] data = asen.GetBytes(textToSend);

        stm.Write(data,0,data.Length);

        //You might want to wait a bit for an answer (Thread.Sleep or simething)

        byte[] responseData = new byte[1024];
        string textRecevided = "";
        int read = 0;               
        do {  
            read = stm.Read(responseData, 0, responseData.Length);
            for (int i=0; i < read; i++)
            {
                textRecevided += (char)responseData[i];
            }           
        } while (read > 0);

        Console.Write(textRecevied);

        tcpclnt.Close();
    }

}

你的问题范围很广,可以轻易地通过巡回回答。

您正在研究的是<代码>Socket/code>。但就你的情况而言,我会使用<代码>TcpClient,因为它使处理更为容易。
