C#问题,高手来看看,我搜索到了MP3文件,在listbox列出来了想用 axWindowsMediaPlayer1.Ctlcontrols.play()

Mp3Player.URL = LvPlayList.SelectedItems[0].Tag.ToString();
Mp3Player.Ctlcontrols.play(); // 开始播放

string FilePath = sstr; // 获取音乐完整文件路径

// 获取音乐名
string SongName = FilePath.Substring(FilePath.LastIndexOf('\\') + 1);
ListViewItem lv = new ListViewItem(SongName); // 根据音乐名生成一个列表项
lv.Tag = FilePath; // 将音乐名的完整路径存放在列表项的Tag标记属性中，方便读取
lv.ImageIndex = 1;
LvPlayList.Items.Add(lv); // 添加

protected void AllSelected_CheckedChanged(object sender, EventArgs e)
{
CheckBox allSelected = (CheckBox)sender;

if (allSelected.Checked)
{
for (int i = 0; i < GridView1.Rows.Count; i++)
{
CheckBox selected = (CheckBox)GridView1.Rows[i].FindControl("Selected");

selected.Checked = true;
}
}
else
{
for (int i = 0; i < GridView1.Rows.Count; i++)
{
CheckBox selected = (CheckBox)GridView1.Rows[i].FindControl("Selected");

selected.Checked = false;
}
}
