一、简介

本文主要参考相关网页，进行设计，实现简单的基于WinForm的Socket TCP协议 实现端到端（服务器与客户端）图片传输。相关网址为

https://blog.csdn.net/z5976749/article/details/40743487

本文知识的主要继承是来自我的上一篇博客：

C#.网络编程 Socket基础（一）Socket TCP协议 实现端到端（服务器与客户端）简单字符串通信https://blog.csdn.net/xpj8888/article/details/83383355

二、知识准备以及其注意点

知识准备：

本位主要基于C#,WinForm，Socket类，来实现端到端的图片传输。关于WinForm的快速入门，参考：

C#图形界面入门 Winform  https://jingyan.baidu.com/article/17bd8e5233c09f85aa2bb84d.html

注意点（由于首次应用Winform，对基本的细节做一些笔记）：

1、Form1_Load默认加载：

2、必须用this.button1.Click += new System.EventHandler(this.button1_Click)。若是用this.button1.Click += button1_Click;

移动控件button1后，this.button1.Click += button1_Click会不见。

3、良好的设计习惯是，必须先放控件，后设计代码逻辑。

三、完整的代码如下

服务器：

1、Form.cs[设计]：

2、Form.cs（主要用来处理控件的逻辑）：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Drawing.Imaging;
using System.IO;
using System.Linq;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace SocketServer_SendImage
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        //Form1_Load表示默认的加载，相当于初始化。
        private void Form1_Load(object sender, EventArgs e)
        {
            lab_pro.Text = "接收:0/100";
            //button1.Text = "BBBBB";
        }
        /// <summary>
        /// 开启服务
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void button1_Click(object sender, EventArgs e)
        {
            //MessageBox.Show(lab_pro.Text);
            button1.Text = "监听中...";
            button1.Enabled = false;
            Socket receiveSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            IPEndPoint hostIpEndPoint = new IPEndPoint(IPAddress.Parse("1.1.1.2"), 8888);

            //设置接收数据缓冲区的大小
            byte[] b = new byte[4096];
            receiveSocket.Bind(hostIpEndPoint);
            //监听
            receiveSocket.Listen(2);
            //接受客户端连接
            Socket hostSocket = receiveSocket.Accept();
            //如何确定该数组大小
            MemoryStream fs = new MemoryStream();

            int length = 0;
            //每次只能读取小于等于缓冲区的大小
            while ((length = hostSocket.Receive(b)) > 0)
            {
                fs.Write(b, 0, length);

                if (progressBar1.Value < 100)
                {
                    progressBar1.Value++;
                    lab_pro.Text = "接收:" + progressBar1.Value + "/100";
                }

            }
            progressBar1.Value = 100;
            lab_pro.Text = "接收:" + progressBar1.Value + "/100";
            fs.Flush();
            Bitmap Img = new Bitmap(fs);
            Img.Save(@"reveive.jpg", ImageFormat.Png);

            //关闭写文件流
            fs.Close();
            //关闭接收数据的Socket
            hostSocket.Shutdown(SocketShutdown.Receive);
            hostSocket.Close();
            //关闭发送连接
            receiveSocket.Close();

            //}


        }

    }
}

3、Form.Designer.cs（主要用来设计控件的属性，外观、颜色、事件记录啊等等）

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Drawing.Imaging;
using System.IO;
using System.Linq;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace SocketServer_SendImage
{
    public partial class Form1: Form
    {
        /// <summary>
        /// 必需的设计器变量。
        /// </summary>
        private System.ComponentModel.IContainer components = null;

        /// <summary>
        /// 清理所有正在使用的资源。
        /// </summary>
        /// <param name="disposing">如果应释放托管资源，为 true；否则为 false。</param>
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }

        #region Windows 窗体设计器生成的代码

        /// <summary>
        /// 设计器支持所需的方法 - 不要修改
        /// 使用代码编辑器修改此方法的内容。
        /// </summary>
        private void InitializeComponent()
        {
            this.button1 = new System.Windows.Forms.Button();
            this.progressBar1 = new System.Windows.Forms.ProgressBar();
            this.lab_pro = new System.Windows.Forms.Label();
            this.SuspendLayout();
            // 
            // button1
            // 
            this.button1.ForeColor = System.Drawing.Color.Red;
            this.button1.Location = new System.Drawing.Point(194, 120);
            this.button1.Name = "button1";
            this.button1.Size = new System.Drawing.Size(199, 72);
            this.button1.TabIndex = 0;
            this.button1.Text = "开启服务\r\n";
            this.button1.UseVisualStyleBackColor = true;
            this.button1.Click += new System.EventHandler(this.button1_Click);
            // 
            // progressBar1
            // 
            this.progressBar1.Location = new System.Drawing.Point(79, 234);
            this.progressBar1.Name = "progressBar1";
            this.progressBar1.Size = new System.Drawing.Size(427, 44);
            this.progressBar1.TabIndex = 1;
            // 
            // lab_pro
            // 
            this.lab_pro.Font = new System.Drawing.Font("宋体", 11.25F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(134)));
            this.lab_pro.Location = new System.Drawing.Point(220, 195);
            this.lab_pro.Name = "lab_pro";
            this.lab_pro.Size = new System.Drawing.Size(158, 27);
            this.lab_pro.TabIndex = 2;
            this.lab_pro.Text = "接收:0/100";
            this.lab_pro.UseWaitCursor = true;
            // 
            // Form1
            // 
            this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 12F);
            this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
            this.ClientSize = new System.Drawing.Size(599, 428);
            this.Controls.Add(this.lab_pro);
            this.Controls.Add(this.progressBar1);
            this.Controls.Add(this.button1);
            this.Name = "Form1";
            this.Text = "服务器";
            this.ResumeLayout(false);

        }



        #endregion

}

4、Server.cs(系统文件的入口程序，简单的工程程序，一般不用修改这个)

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Drawing.Imaging;
using System.IO;
using System.Linq;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace SocketServer_SendImage
{
    static class Server
    {
        /// <summary>
        /// 应用程序的主入口点。
        /// </summary>
        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new Form1());
        }
    }
}

        /// <summary>

            if (this.openFileDialog1.ShowDialog() == DialogResult.OK)
            {
                try
                {
                    string path = this.openFileDialog1.FileName;
                    lab_path.Text = path;
                    FileStream fs = new FileStream(path, FileMode.Open, FileAccess.Read);
                    imgByte = new Byte[fs.Length];
                    fs.Read(imgByte, 0, imgByte.Length);
                    fs.Close();
                }
                catch (Exception)
                {
                }
            }
        }
        /// <summary>
        /// 向服务器发送数据

        private void btn_send_Click(object sender, EventArgs e)
        {
            //实例化socket        
            IPEndPoint ipendpiont = new IPEndPoint(IPAddress.Parse("1.1.1.2"), 8888);
            sendsocket.Connect(ipendpiont);
            MessageBox.Show("服务器IP:" + sendsocket.RemoteEndPoint);
            sendsocket.Send(imgByte);
            sendsocket.Shutdown(System.Net.Sockets.SocketShutdown.Send);

    }
