使用Windows窗体应用程序，基于Windows Media Player组件写一个简单的播放器，功能比较简陋，通过打开文件按钮来选取音乐所在的地址，还有4个按钮，分别是：播放，结束，暂停/继续，歌曲信息

添加AxWindowsMediaPlayer控件的方法：在”工具箱”中单击右键，选择”选择项”菜单，打开”选择工具箱项”窗口，选择”COM”组件”标签，在列表中找到并勾选”Windows Media Player”组件，单击”确定”按钮。将该组件添加到指定的工具箱选项卡中，然后在工具箱里面找 Windows Media Player 控件，拉到form里面即可

OpenFileDialog控件也许注意

赋个截图，按暂停按钮时停止播放，再按一次就继续播放
