所以我终于找到了在这门课上帮助我的帖子之一

using System;
using System.Text;
using System.Runtime.InteropServices;
using System.IO;

namespace MidiProgram
{
/// <summary>
/// MCIPlayer is based off code by Slain.
/// Found here: http://www.sadeveloper.net/Articles_View.aspx?articleID=212
/// </summary>
public class MCIPlayer
{

    private static readonly string sAlias = "TeaTimerAudio";

    [DllImport("winmm.dll")]
    private static extern long mciSendString(string strCommand, StringBuilder strReturn, int iReturnLength, IntPtr hwndCallback);
    [DllImport("Winmm.dll")]
    private static extern long PlaySound(byte[] data, IntPtr hMod, UInt32 dwFlags);

    public static void Play(string sFile)
    {
        _Open(sFile);
        _Play();
    }
    public static void Stop()
    {
        _Close();
    }

    private static void _Open(string sFileName)
    {
        if (_Status() != "")
            _Close();

        string sCommand = "open \"" + sFileName + "\" alias " + sAlias;
        mciSendString(sCommand, null, 0, IntPtr.Zero);
    }

    private static void _Close()
    {
        string sCommand = "close " + sAlias;
        mciSendString(sCommand, null, 0, IntPtr.Zero);
    }

    private static void _Play()
    {
        string sCommand = "play " + sAlias;
        mciSendString(sCommand, null, 0, IntPtr.Zero);
    }

    private static string _Status()
    {
        StringBuilder sBuffer = new StringBuilder(128);
        mciSendString("status " + sAlias + " mode", sBuffer, sBuffer.Capacity, IntPtr.Zero);
        return sBuffer.ToString();
    }
}
}

但是我似乎发现了一点问题，整个程序发出声音，但显然它输出到（microsoft gs波表合成器）在这个类中有没有办法我可以改变midi输出的方式或者它只是在播放就像那种形式的 MediaPlayer，请告诉我，这是我项目的最后一步，只是一个简单的代码，让我说我能做到我可以通过整数或名称指定 midi 设备，我的意思是MIDI 设备订购！
