在之前 播放一般用SoundPlayer 类 但是这个有缺点 ：无法暂停，为此引进Windows Media Player
在工具箱找控件Windows Media Player
属性设置，快捷键：R
1. Windows Media Player
例子：
private void Pause_Click(object sender, EventArgs e)
{
musicPlayer.Ctlcontrols.pause(); //暂停播放
}
private void Play_Click(object sender, EventArgs e)
{
musicPlayer.Ctlcontrols.play(); //开始播放
}
private void Stop_Click(object sender, EventArgs e)
{
musicPlayer.Ctlcontrols.stop(); //停止播放
}
private void Form1_Load(object sender, EventArgs e)
{
musicPlayer.URL = @"G:\c#\第十五章\mp3\半城烟沙.mp3";
musicPlayer.Ctlcontrols.stop();
}
private void PlayOrPause_Click(object sender, EventArgs e)
{
if (PlayOrPause.Text == "播放")
{
musicPlayer.Ctlcontrols.play();
PlayOrPause.Text = "暂停";
}
else if (PlayOrPause.Text == "暂停")
{
musicPlayer.Ctlcontrols.pause();//暂停
PlayOrPause.Text = "播放";
}
}
string[] path;
private void SelectFile_Click(object sender, EventArgs e)
{
OpenFileDialog open = new OpenFileDialog();
open.Title = "选择文件"; //对话框标题
open.Filter = "音乐文件|*.mp3|所有文件|*.*"; //文件类型
open.Multiselect = true; //多选文件
open.ShowDialog(); //显示对话框
open.InitialDirectory = @"G:\c#\第十五章\mp3"; //默认路径
path = open.FileNames;
for (int i = 0; i < path.Length; i++)
listPath.Items.Add(Path.GetFileName(path[i]));
}
private void listPath_DoubleClick(object sender, EventArgs e)
{
if(listPath.Items.Count<=0)
{
MessageBox.Show("请先选择文件");
return; //结束进程
}
//为了解决点击空白选项处，需要做异常处理
try
{
musicPlayer.URL = path[listPath.SelectedIndex];
musicPlayer.Ctlcontrols.play();
PlayOrPause.Text = "暂停";
}
catch (Exception)
{
throw;
}
}在项目中添加图片
private void btnLast_Click(object sender, EventArgs e)
{
int index = listPath.SelectedIndex; //获取listPath索引
//当listBox控件的selectMode属性是 MultiExtended时
//导致无法正常上一曲的操作，需要先将之前的索引值清空
listPath.SelectedIndices.Clear();
--index;
if (index < 0)
index = listPath.Items.Count - 1;
listPath.SelectedIndex = index;
musicPlayer.URL = path[listPath.SelectedIndex];
}
private void btnNext_Click(object sender, EventArgs e)
{
int index = listPath.SelectedIndex;
//当listBox控件的selectMode属性是 MultiExtended时
//导致无法正常下一曲的操作，需要先将之前的索引值清空
listPath.SelectedIndices.Clear();
++index;
if (index >= listPath.Items.Count)
index = 0;
listPath.SelectedIndex = index;
musicPlayer.URL = path[listPath.SelectedIndex];
}
private void DeletMenuItem_Click(object sender, EventArgs e)
{
//删除listBox中的某些选项
//1. 在窗体中添加 ContextMenuStrip 控件， 并在控件中添加删除事件
//2. 将ListBox与ContextMenuStrip控件联系起来：设置ListBox控件中的ContextMenuStrip属性，选择控件的名称
//先删除路径集合，再删除listBox列表
//原因：首先明确，列表集合是根据路径集合来添加的，
//如果先删列表集合，导致，列表里的内容和路径集合的内容对不上号
int count = listPath.SelectedIndices.Count;
//for (int i = 0; i < path.Length; i++)
//{
// MessageBox.Show(path[i]);
//}
for (int i = 0; i < count; i++)
{
//先删除路径集合
liBox.RemoveAt(listPath.SelectedIndex);
//再删除listBox列表
listPath.Items.RemoveAt(listPath.SelectedIndex);
}
}
private void Pictrue_Click(object sender, EventArgs e)

}
private void Time_Click(object sender, EventArgs e)
{
//设置前提： 添加timer控件，切记将控件中的TClick 设为time_clik
//自动播放下一曲方法：
//1. 想办法获取歌曲总时长
//2. 获取播放时长，
//3. 进行对比，如果播放时长大于等于视频的时长，就进行下一曲
//currentMedia //当前媒体属性
//currentMedia.duration:double; 媒体总长度
//currentMedia.durationString:string; 媒体总长度，字符串格式。如“03:24”
//Ctlcontrols.currentPosition:double; 当前进度
// Ctlcontrols.currentPositionString:string; 当前进度，字符串格式。如“00:23”
//如果播放状态等于正在播放
if (musicPlayer.playState == WMPLib.WMPPlayState.wmppsPlaying)
