Question

点击ListBox，我将音频文件添加到Button。然后OpenFileDialog（下面的代码）有效。我使用添加的文件ListBox来播放（下面的代码）。我点击button_play。这儿存在一个问题。当我点击Button进行排序时使用listBox1.Sorted = true。排序后，不播放应播放的音频文件。播放前在此位置的音频文件。也就是说，如果所有歌曲都有一个数字，那么在排序后只更改了名称，但数字没有改变。当您点击button_play时，会按号码播放。

private void button_add_Click(object sender, EventArgs e)
        {
            openFileDialog1.ShowDialog();
            label_load.Text = list_catalog.Items.Count.ToString();
        }

private void openFileDialog1_FileOk(object sender, CancelEventArgs e)
{
    foreach (String file in openFileDialog1.FileNames)
    {
        if (list_catalog.Items.Contains(Vars.GetFileName(file)))
        {
        }
        else
        {
            Vars.Files.Add(file);
            list_catalog.Items.Add(Vars.GetFileName(file));
            hello.Visible = false;
        }
    }
}

private void button_play_Click(object sender, EventArgs e)
        {

                string current = Vars.Files[list_catalog.SelectedIndex];
                Vars.CurrentTrackNumber = list_catalog.SelectedIndex;
                BassLike.Play(current, BassLike.Volume);
                label_time1.Text = TimeSpan.FromSeconds(BassLike.GetPosOfStream(BassLike.Stream)).ToString();
                label_time2.Text = TimeSpan.FromSeconds(BassLike.GetTimeOfStream(BassLike.Stream)).ToString();
                xrewind.Maximum = BassLike.GetTimeOfStream(BassLike.Stream);
                xrewind.Value = BassLike.GetPosOfStream(BassLike.Stream);
                timer1.Enabled = true;

        }

我认为这会奏效......

string current = list_catalog.SelectedItem as string;
Vars.CurrentTrackNumber = Vars.Files.IndexOf(current);

更改ListBox中的选择
