我怎样可以暂停使用C＃的MP3文件？ [英] How can I pause an MP3 file using C#?

问题描述

我有这个类我在一个网站上找到：

I have this class I found in a website:

class MP3Handler
{
    private string _command;
    private bool isOpen;
    [DllImport("winmm.dll")]

    private static extern long mciSendString(string strCommand, StringBuilder strReturn, int iReturnLength, IntPtr hwndCallback);

    public void Close()
    {
        _command = "close MediaFile";
        mciSendString(_command, null, 0, IntPtr.Zero);
        isOpen = false;
    }

    public void Open(string sFileName)
    {
        _command = "open \"" + sFileName + "\" type mpegvideo alias MediaFile";
        mciSendString(_command, null, 0, IntPtr.Zero);
        isOpen = true;
    }

    public void Play(bool loop)
    {
        if (isOpen)
        {
            _command = "play MediaFile";
            if (loop)
                _command += " REPEAT";
            mciSendString(_command, null, 0, IntPtr.Zero);
        }
    }
