如何在客户端应用程序中使我的winsock控件连接到服务器应用程序，该应用程序在c＃windows窗体中也有一个winsock控件 [英] How to make my winsock control in client application to connect to server application which also has a winsock control in c# windows forms

问题描述

你好我的名字是过去1周的vishal我一直在打破如何在客户端应用程序中使我的winsock控件连接到服务器应用程序，该应用程序在c＃windows窗体中也有一个winsock控件？

所以我有一个名为： Winsock客户端的客户端应用程序，它有一个名为： Form1 的表单，它还有一个名为： Winsock1 的winsock控件，协议： 0-sckTCPProtocol 并且可见： true



以下是我的 c＃代码 Winsock客户端的Form1（客户端应用程序）：

Hi my name is vishal for past 1 week i have been breaking my head on How to make my winsock control in client application to connect to server application which also has a winsock control in c# windows forms?
So i have a client application named:Winsock client which has a form named:Form1 which also has a winsock control named:Winsock1,Protocol:0-sckTCPProtocol and visible:true

Given below is my c# code of Form1 of Winsock client(client application):

namespace Winsock_client
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
private void btnConnect_Click(object sender, EventArgs e)
        {
            Winsock1.RemoteHost = "192.168.0.118" ;//Change this to your host ip
            Winsock1.RemotePort = 7777;
            Winsock1.Connect();
            shpGo.Visible=true;
            txtPrice.Focus();
        }
private void btnDisconnect_Click(object sender, EventArgs e)
        {
            Winsock1.Close();
            shpGo.Visible=false;
            shpWait.Visible =false;
            shpError.Visible = true;
        }
private void Winsock1_SendComplete(object sender, EventArgs e)
        {
            label3.Text = "Completed Data Transmission";
        }
 private void Winsock1_DataArrival(object sender, AxMSWinsockLib.DMSWinsockControlEvents_DataArrivalEvent e)
        {
            string sData="";
            Object cand = (object)sData;
            Winsock1.GetData(ref cand);
            sData = (String)cand;
            txtPrice.Text = sData;
            label3.Text = "Received Data";
            shpGo.Visible = true;
            shpWait.Visible = false;
            shpError.Visible = false;
        }
 private void btnSend_Click(object sender, EventArgs e)
        {
            
           if(Winsock1.CtlState==2)
           {
            Winsock1.SendData(txtPrice.Text);
            shpGo.Visible =true;
            label3.Text = "Sending Data";
           }
            else
           {
            shpGo.Visible=false;
            shpWait.Visible=false;
            shpError.Visible =true;
            label3.Text = "Not currently connected to host";
           }
        }

所以我还有一个名为： Winsock服务器的服务器应用程序，它有一个名为：<的表单b> Form1 并且还有一个名为： Socket 的winsock控件，协议： 0-sckTCPProtocol 并且可见： true



下面给出的是 Winsock服务器的Form1的c＃代码（服务器应用程序）：

So i also have a server application named:Winsock server which has a form named:Form1 and also has a winsock control named:Socket,Protocol:0-sckTCPProtocol and visible:true

Given below is my c# code of Form1 of Winsock server(Server application):

namespace Winsock_server
{
    public partial class Form1 : Form
    {
        int iSockets;
        string sServerMsg;
        string sRequestID;
        Socket sck;
        public Form1()
        {
            InitializeComponent();
            sck = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
            sck.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.ReuseAddress, true);
        }
        private string GetLocalIP()
        {
            IPHostEntry host;
            host = Dns.GetHostEntry(Dns.GetHostName());
            foreach (IPAddress ip in host.AddressList)
            {
                if (ip.AddressFamily == AddressFamily.InterNetwork)
                {
                    return ip.ToString();
                }
            }
            return "127.0.0.1";
        }
private void Form1_Load(object sender, EventArgs e)
        {
            txtHostID.Text = Socket.LocalHostName;
            txtAddress.Text = Socket.LocalIP;
            Socket.LocalPort = 7777;
             sServerMsg = "Listening to port: " + Socket.LocalPort;
            listBox1.Items.Add(sServerMsg);
            Socket.Listen();
        }
private void Socket_CloseEvent(object sender, EventArgs e)
        {
            sServerMsg = "Connection closed: " + Socket.RemoteHostIP;
            listBox1.Items.Add(sServerMsg);
            Socket.Close();
            iSockets = iSockets - 1;
            txtConnections.Text = iSockets.ToString();
        }
private void Socket_ConnectionRequest(object sender, AxMSWinsockLib.DMSWinsockControlEvents_ConnectionRequestEvent e)
        {
            sServerMsg = "Connection request id " + e.requestID + " from " + Socket.RemoteHostIP;
            listBox1.Items.Add(sServerMsg);
            sRequestID = e.requestID.ToString();
            iSockets = iSockets + 1;
            txtConnections.Text = iSockets.ToString();
        }
private void Socket_DataArrival(object sender, AxMSWinsockLib.DMSWinsockControlEvents_DataArrivalEvent e)
        {
            string incommingData = "";
            Object rend = (object)incommingData;
            Socket.GetData(ref rend);
            incommingData = (String)rend;
            listBox1.Text = listBox1.Text + System.Environment.NewLine + incommingData;
        }

所以我执行我的客户端应用程序（ Winsock客户端）和服务器应用程序（ Winsock < b>服务器）同时 客户端 - 服务器通信。

所以我能够连接我的客户端应用程序（ Winsock客户端）部分，下面是c＃代码：

So i execute my client application(Winsock client) and server application(Winsock server) simultaneously for client-server communication.
So i am able to connect my client application(Winsock client) partially,Given below is c# code of that:

private void btnConnect_Click(object sender, EventArgs e)
        {
            Winsock1.RemoteHost = "192.168.0.118" ;//Change this to your host ip
            Winsock1.RemotePort = 7777;
            Winsock1.Connect();
            shpGo.Visible=true;
            txtPrice.Focus();
        }

但是在客户端应用程序（ Winsock 客户端）之间建立连接后出现此问题当我在 Winsock客户端的 Form1 中的文本框中输入名称为 txtPrice 的文件框中的数据和服务器应用程序（ Winsock服务器）时（客户端应用程序）当我在 Winsock客户端中单击 btnSend 时，将在文本框中输入的数据（ txtPrice ）发送到名为的列表框： listBox1 出现在 Winsock 服务器（服务器应用程序）的Form1中，下面给出的是c＃代码：

But here is the problem after connection is established between client application(Winsock client) and Server application(Winsock server) when i enter data in textbox named:txtPrice in Form1 of Winsock client(client application) and when i click btnSend in Winsock client to send data entered in textbox(txtPrice) to listbox named:listBox1 which is present in Form1 of Winsock server(Server application) given below is c# code of that:

private void btnSend_Click(object sender, EventArgs e)
        {
           if(Winsock1.CtlState==2)
           {
            Winsock1.SendData(txtPrice.Text);
            shpGo.Visible =true;
            label3.Text = "Sending Data";
           }
            else
           {
            shpGo.Visible=false;
            shpWait.Visible=false;
            shpError.Visible =true;
            label3.Text = "Not currently connected to host";
           }
        }

在 Winsock客户端 txtPrice （Form1中的文本框控件）中输入数据后/ b>（客户端应用程序），当我点击/按 btnSend （Winsock客户端的Form1中的按钮控件）时，我总是收到消息当前未连接到主机 label3 （ Winsock客户端（客户端应用程序）的Form1中的标签控件）。



此错误让我惊叹不已如何在名为： Winsock客户端的客户端应用程序中创建/启用名为： Winsock1 的winsock控件，以连接到名为： Socket 的winsock控件服务器应用程序名称： Winsock服务器？



任何人都可以帮我解决如何在客户端应用程序（Winsock客户端）和服务器应用程序之间建立连接（ Winsock服务器）仅在c＃windows窗体中使用Winsock控件？



由于我的 BOSS 命令，我必须仅使用Winsock控件。

有人可以帮帮我吗？任何人都可以帮助我/指导我如何解决我的问题？任何帮助/指导解决这个问题将不胜感激！

After entering data in txtPrice(textbox control in Form1) of Winsock client(Client application) and when i click/press btnSend(button control in Form1 of Winsock client) i always get message "Not currently connected to host" in my label3(label control in Form1 of Winsock client(client application)).

This error makes me wonder how to make/enable my winsock control named:Winsock1 present in client application named:Winsock client to connect to winsock control named:Socket present in server application name:Winsock server?

Can anyone help me on how to establish connection between client application(Winsock client) and server application(Winsock server) using Winsock controls only in c# windows forms?

I have to use only Winsock controls for this purpose because of my BOSS's orders.
Can anyone help me Please? Can anyone help me/guide me on how to solve my problem? Any help/guidance in solving of this problem would be greatly appreciated!
