用axWindwosMediaPlayer C＃恢复歌曲 [英] Resume song with axWindwosMediaPlayer C#

问题描述

我在使用C＃制作的媒体播放器遇到了一些问题，我认为这将是最后一个问题..



我有两个按钮：播放和暂停。单击播放时，正在播放列表框中的选定歌曲。如果我单击暂停，则歌曲会正确暂停。但如果我再次点击播放按钮继续播放歌曲，它会重新播放我正在播放的歌曲。



我正在使用：

I'm having some problems with a media player that I'm making in C#, I think this will be the last problem..

I have two buttons: Play and Pause. When I click Play, a selected song from a listbox is being played. If I click Pause, the song pauses correctly. But if I click on Play button again to resume the song, it restarts the song I was playing.

I'm using:

private void button3_Click(object sender, EventArgs e) //Play Button
       { 
          axWindowsMediaPlayer1.URL = mediaList[listBox1.SelectedIndex];
          if(axWindowsMediaPlayer1.playState == WMPLib.WMPPlayState.wmppsPaused)
               {
                  axWindowsMediaPlayer1.Ctlcontrols.play();
               }else
               {
                  axWindowsMediaPlayer1.Ctlcontrols.pause();
               }
       }

mediaList 是一个列表用于保存listBox1上的播放列表。



先谢谢。

mediaList is a list for saving the playlist on listBox1.

Thanks in Advance.

推荐答案

假设您要切换播放和暂停使用按钮。如果未设置URL，则只需设置一个。所以你可以先检查URL如下所示

Assume you want to toggle Play and Pause using button. In case of URL not set then only you need to set one. so you can check URL first as below

//code 1
if(!string.IsNullOrEmpty(axWindowsMediaPlayer1.URL)
{
   // URL set, you can pause or play current video 
   // check below Code2
}else
{
   // need to set the url from your mediaList selected item and play the video from beginning 
}

如果您已经设置了网址，那么您的视频可能会被暂停，那么您需要播放它，否则您需要暂停它

if you already have URL set then your video may be paused then you need to play it otherwise you need to paused it

//code2
if(axWindowsMediaPlayer1.playState == WMPLib.WMPPlayState.wmppsPaused){
    // video paused, resume it  
    axWindowsMediaPlayer1.Ctlcontrols.play();
}else{
    // otherwise pause the video
    axWindowsMediaPlayer1.Ctlcontrols.pause();
}

完整代码：

full code:

private void button3_Click(object sender, EventArgs e) 
       { 
          if(!string.IsNullOrEmpty(axWindowsMediaPlayer1.URL)
          {
             if(axWindowsMediaPlayer1.playState == WMPLib.WMPPlayState.wmppsPaused){
                axWindowsMediaPlayer1.Ctlcontrols.play();
             }else{
               axWindowsMediaPlayer1.Ctlcontrols.pause();
             }
          }else
          {
             axWindowsMediaPlayer1.URL = mediaList[listBox1.SelectedIndex];
             axWindowsMediaPlayer1.Ctlcontrols.play();
          }
          
       }
