Posted 2021-12-02

namespace _14.双击播放音乐
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
//新建一个泛型集合来存储音乐文件全路径
List<string> listSong = new List<string>();
private void Form1_Load(object sender, EventArgs e)
{
//程序运行时加载音乐文件名称到listBox
//获取音乐文件全路径
string[] path = Directory.GetFiles(@"C:\Users\Administrator.USER-20180925HC\Desktop\pic", "*.wav");
//通过循环对listBox赋值
for (int i = 0; i < path.Length; i++)
{
string fileName = Path.GetFileName(path[i]);
listBox1.Items.Add(fileName);
//将音乐文件的全路径存到泛型集合中
listSong.Add(path[i]);
}
}

    private void listBox1_DoubleClick(object sender, EventArgs e)
    {
        //双击音乐文件，播放音乐
        //新建音乐文件对象
        SoundPlayer sp = new SoundPlayer();
        sp.SoundLocation = listSong[listBox1.SelectedIndex];
        sp.Play();
    }
}
