## 实现 ##

新建窗体程序，然后从工具箱中拖拽DataGridView控件，然后在控件右上角点击新增列，设置好每列

的Name属性和Headertext属性。

### 新建Video类 ###

项目-右击-新增-类

using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Text;
    
    namespace MyPlayer
    {
        class Video
        {
            public Video(string id, string name, string path)
            {
                this.ID = id;
                this.Name = name;
                this.Path = path;
            }
    
            //编号
            public string ID { get; set; }
    
            //名称
            public string Name { get; set; }
    
            //路径
            public string Path { get; set; }
        }
    }

### 初始化播放列表 ###

首先声明一个全局的视频列表对象

List<Video> videoList = new List<Video>();

然后在窗体的构造方法中添加初始化播放列表的方法。

其位置

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 2][]

在Init方法中

public void Init()
            {
                videoList.Add(new Video("1", "前言", @"F:\全网首个微信小程序开发视频教程\1.0前言.mp4"));
                videoList.Add(new Video("2", "课程介绍", @"F:\全网首个微信小程序开发视频教程\1.1课程介绍,定个小目标.mp4"));
                videoList.Add(new Video("3", "开发文档", @"F:\全网首个微信小程序开发视频教程\1.2开发文档简读，了解全貌.mp4"));
                //设置DataGridView的数据源
                UpdateDgv();
            }

这里视频采用的是本地绝对路径的视频。

播放列表添加完之后，将视频列表赋值给DataGridView。

public void UpdateDgv()
            {
                //设置DataGridView的数据源
                this.dgvVedioList.DataSource = videoList;
            }

其中dgvVedioList就是对应的DataGridView控件的name属性。

### 新建播放页面 ###

项目-右键-添加-Windows窗体

然后在工具箱中拖拽一个WindowsMediaPlayer组件。

VS2013工具箱中使用WindowsMediaPlyer控件：

添加播放组件后

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 3][]

编写其Play方法

using System;
    using System.Collections.Generic;
    using System.ComponentModel;
    using System.Data;
    using System.Drawing;
    using System.Linq;
    using System.Text;
    using System.Windows.Forms;
    namespace MyPlayer
    {
        public partial class FrmPlayer : Form
        {
            //独一无二的实例
    
            private static FrmPlayer uniquePlayer;
           
            //私有构造函数
    
            private FrmPlayer()
            {
                InitializeComponent();
            }
            //检查并创建唯一实例
            public static FrmPlayer GetInstance()
            {
                if (uniquePlayer == null)
                {
                    uniquePlayer = new FrmPlayer();
                }
                return uniquePlayer;
            }
    
            //播放节目
            public bool Play(string videoPath)
            {
                try
                {
                    //播放成功后返回true
                    this.wmp.URL = videoPath;
                    return true;
                }
                catch (Exception ex)
                {
                    //播放器异常返回false
                    MessageBox.Show("播放器异常" + ex.Message);
                    return false;
                }
            }
    
            //关闭过程中将实例引用设为null
            private void FrmPlayer_FormClosing(object sender, FormClosingEventArgs e)
            {
                FrmPlayer.uniquePlayer = null;
            }
    
            private void wmp_Enter(object sender, EventArgs e)
            {
    
            }
        }
    }

### 配置右键菜单 ###

回到播放列表的页面，拖拽一个ContextMenuStrip组件，设置右键播放菜单。

然后将DataGridView与之关联。具体可参照如下：

C\# Winform程序中DataGridView中使用ContextMenuStrip实现右键菜单：

### 配置右键菜单的点击事件 ###

private void tsmiPlayer_Click(object sender, EventArgs e)
            {
                //获取播放路径
                string videoPath = this.dgvVedioList.CurrentRow.Cells["path"].Value.ToString();
                if (!File.Exists(videoPath))
                {
                    MessageBox.Show("文件不存在！","提示");
                    return;
                }
                //创建单例--视频播放页面窗体
                FrmPlayer myPlayer = FrmPlayer.GetInstance();
                bool result = myPlayer.Play(videoPath);
                if (result)
                {
                    //显示
                    myPlayer.Show();
                }
                else
                {
                    //释放
                    myPlayer.Dispose();
                }
            }
