运行项目c#音乐播放器时出错

Question

嗨，这是一个简单的音乐播放器应用程序，我在 YouTube 视频之后使用 c# 开发，它就在最后，现在程序将无法正常运行，即播放选定的音乐，如您所见附图错误为“错误CS0103当前上下文中不存在名称'axWindowsMediaPlayer'”

不知道是不是编译器错误

        {
            InitializeComponent();
        }

        //Create Global variables of string type array to save the titles or name the of the songs and the path (location) of the songs 
        string[] paths, files;

        private void btnSelectSongs_Click(object sender, EventArgs e)
        {
            // code for selecting songs 
            OpenFileDialog ofd = new OpenFileDialog();

            // code for selecting multiple tracks 
            ofd.Multiselect = true;
            ofd.Filter = "All Supported Audio | *.mp3; *.wma | MP3s | *.mp3 | WMAs | *.wma";

            if (ofd.ShowDialog()==System.Windows.Forms.DialogResult.OK)
            {
                files = ofd.SafeFileNames; // this is to save name of the songs in the files array
                paths = ofd.FileNames; // this is to save the paths/location of the songs in the path array

                // after that we display the music titles in the listbox
                for (int i = 0; i <files.Length; i++)
                {

                    listBoxSongs.Items.Add(files[i]); // this displays the songs in the list box
                }
            }
        }

        private void listBoxSongs_SelectedIndexChanged(object sender, EventArgs e)
        {
            // code for playing the sellected music 
           axWindowsMediaPlayer.URL = paths[listBoxSongs.SelectedIndex];
        }

        private void pictureBox1_Click(object sender, EventArgs e)
        {
            // code for closing the app 
            this.Close();

        }
    }
}

This is how the error looks on visual studio

点击媒体播放器>属性>名称。检查播放器的名称，然后在您的代码中使用该名称。
