如何使用 axmediaplayer 播放播放列表中的下一个项目？

好的，我有问题，我编写了此代码来根据列表框中列出的项目播放 axmediaplayer。首先，我编写此代码以使用 opendialog 制作列表：

 private string[] files, path;
 private void button1_Click(object sender, EventArgs e)
    {
        if (openFileDialog1.ShowDialog() == System.Windows.Forms.DialogResult.OK)
        {
            files = openFileDialog1.SafeFileNames;
            path = openFileDialog1.FileNames;
            for (int i = 0; i < files.Length; i++) {
                listBox1.Items.Add(files[i]);
            }
        }
    }

然后当列表框索引更改时（当列表框中的项目单击时）使用此代码播放音乐：

private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
{
    axWindowsMediaPlayer1.URL = path[listBox1.SelectedIndex];
}

它工作正常，然后我希望播放器自动移动到下一首歌曲基于我的列表框中的项目。使用事件 PlayStateChange，所以我将此代码

private void axWindowsMediaPlayer1_PlayStateChange(object sender, AxWMPLib._WMPOCXEvents_PlayStateChangeEvent e)
{
    if (axWindowsMediaPlayer1.playState == WMPLib.WMPPlayState.wmppsMediaEnded) 
    {
         if(listBox1.SelectedIndex < files.Length - 1)
         {
            listBox1.SelectedIndex = listBox1.SelectedIndex + 1;
         }
    }
}

更改为选定的索引，但播放器不会自动播放下一首歌曲。我必须手动单击播放按钮才能播放列表。有人可以帮我吗？

ok i have question, i made this code to play axmediaplayer base on item listed on listbox.
first i make this code to make a list using opendialog :

 private string[] files, path;
 private void button1_Click(object sender, EventArgs e)
    {
        if (openFileDialog1.ShowDialog() == System.Windows.Forms.DialogResult.OK)
        {
            files = openFileDialog1.SafeFileNames;
            path = openFileDialog1.FileNames;
            for (int i = 0; i < files.Length; i++) {
                listBox1.Items.Add(files[i]);
            }
        }
    }

and then it play the music when the listbox index changed (when the item on the list box cliked) using this code :

private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
{
    axWindowsMediaPlayer1.URL = path[listBox1.SelectedIndex];
}

it works fine, and then i want player to automove to the next song base on item on my listbox. with using events PlayStateChange, so i make this code

private void axWindowsMediaPlayer1_PlayStateChange(object sender, AxWMPLib._WMPOCXEvents_PlayStateChangeEvent e)
{
    if (axWindowsMediaPlayer1.playState == WMPLib.WMPPlayState.wmppsMediaEnded) 
    {
         if(listBox1.SelectedIndex < files.Length - 1)
         {
            listBox1.SelectedIndex = listBox1.SelectedIndex + 1;
         }
    }
}

the selected index change, but the player doesn't auto play the next song. i must click the play button manually in order to play the list. can anyone help me up?

好的，我找到了，解决方案是在播放下一首歌曲之前添加计时器。
首先我添加计时器，应该是timer1。然后我将 playstate 事件更改为如下所示：

private void axWindowsMediaPlayer1_PlayStateChange(object sender, axWMPLib._WMPOCXEvents_PlayStateChangeEvent e)
    {
        if (axWindowsMediaPlayer1.playState == WMPLib.WMPPlayState.wmppsMediaEnded)
        {
            timer1.Interval = 100;
            timer1.Enabled = true;               
        }            
     }

然后在计时器上添加刻度事件，刻度事件是这样的：

 private void timer1_Tick(object sender, EventArgs e)
    {
        if (listBox1.SelectedIndex < files.Length - 1)
        {
            listBox1.SelectedIndex++;
            timer1.Enabled = false;
        }
        else
        {
            listBox1.SelectedIndex = 0;
            timer1.Enabled = false;
        }            
    }

现在它工作正常 ^^

ok i found it, the solution is to add timer before playing the next song.
first im adding timer, that shoud be timer1. and then i change playstate event to something like this :

private void axWindowsMediaPlayer1_PlayStateChange(object sender, axWMPLib._WMPOCXEvents_PlayStateChangeEvent e)
    {
        if (axWindowsMediaPlayer1.playState == WMPLib.WMPPlayState.wmppsMediaEnded)
        {
            timer1.Interval = 100;
            timer1.Enabled = true;               
        }            
     }

then on the timer i adding tick event, the tick event is something like this :

 private void timer1_Tick(object sender, EventArgs e)
    {
        if (listBox1.SelectedIndex < files.Length - 1)
        {
            listBox1.SelectedIndex++;
            timer1.Enabled = false;
        }
        else
        {
            listBox1.SelectedIndex = 0;
            timer1.Enabled = false;
        }            
    }

now its work fine ^^

以下功能对我有用：

    private void axWindowsMediaPlayer1_PlayStateChange(object sender, AxWMPLib._WMPOCXEvents_PlayStateChangeEvent e)
    {
        if ((WMPLib.WMPPlayState)e.newState == WMPLib.WMPPlayState.wmppsMediaEnded)
        {

            timer1.Interval = 100;
            timer1.Start();
            timer1.Enabled = true;   
            timer1.Tick += timer1_Tick;
        }
    }

    private void timer1_Tick(object sender, EventArgs e)
    {
        /// method to play video list items
        myFuntiontoPlayVideo();
        timer1.Enabled = false;
    }

Below functionality worked for me:

    private void axWindowsMediaPlayer1_PlayStateChange(object sender, AxWMPLib._WMPOCXEvents_PlayStateChangeEvent e)
    {
        if ((WMPLib.WMPPlayState)e.newState == WMPLib.WMPPlayState.wmppsMediaEnded)
        {

            timer1.Interval = 100;
            timer1.Start();
            timer1.Enabled = true;   
            timer1.Tick += timer1_Tick;
        }
    }

    private void timer1_Tick(object sender, EventArgs e)
    {
        /// method to play video list items
        myFuntiontoPlayVideo();
        timer1.Enabled = false;
    }
