{

{

{

}
string[] fileEntries = null; //to get all the things in a folder
bool nextsong = false; //to see when the next song should be played
private void button1_Click_1(object sender, EventArgs e)
{
timer1.Start();//start the timer to see when the next song should be played
comboBox1.Items.Clear();
folderBrowserDialog1.ShowDialog();
fileEntries = Directory.GetFiles(folderBrowserDialog1.SelectedPath);
foreach (string filename in fileEntries)
{
string path1 = folderBrowserDialog1.SelectedPath;
string path2 = "desktop.ini";
string outpath = Path.Combine(path1, path2);
if (filename == outpath) // so the desktop.ini don't get counted
{
fileEntries[0] = null;
}

{
string I = Path.GetFileName(filename);
comboBox1.Items.Add(I);
WMP.URL = fileEntries[1];
}
}
}

{
// don't do anything
}
int playing = 1;
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
//to get the combobox playing when you press a song
playing = comboBox1.SelectedIndex;
playing++;
WMP.URL = fileEntries[playing];
}

{
//all this is to get the next song to play but it don't work
if (WMP.status == "stopped" && nextsong == true)
{
if (fileEntries.Length > playing)
{
WMP.URL = fileEntries[playing];
playing++;
}
else
{
playing = 2;
WMP.URL = fileEntries[1];
}

您在这里看到的是，我将文件放在一个文件夹中并尝试播放，但我不使用desktop.ini文件，因为当我尝试播放它时，它将无法正常工作，然后将它们放在一个文件夹中.组合框作为播放列表.
一切正常，但不是应该播放下一首歌曲.
What you see here is that I take the files in a folder and try to play them I don''t use the desktop.ini file because it won''t work when I try to play it of couse then I put them in a combobox as a play list.
It all work but not the thing were it should play the next song.
推荐答案
您做错了.
我知道，我的答案似乎有些模糊，甚至有些晦涩，但问题的质量决定了答案的质量.
You''re doing it wrong.
I know, my answer might seem vague, or even obtuse, but the quality of the question dictates the quality of the answer.
首先，您应该使用一些全局标记，该全局标记将指示玩家是否应该继续玩.
您应该处理 PlayStateChange事件以了解何时播放下一首歌曲.
接下来很容易，使用 IWMPControls :: next()和 IWMPControls :: play()接下来播放的方法列表中的歌曲.
玩这个，你应该不会有问题.
First you should use some global flag which will indicate whether player should continue playing.
You should handle PlayStateChange event to know when to play next song.
Next is easy, use IWMPControls::next() and IWMPControls::play() methods to play next song in the list.
Play with this, you shouldn''t have problems.
我明白了.....
