#endregion
5.定义变量 #region 自定义变量 bool isOpen = false; IntPtr DeviceHandle = IntPtr.Zero; public bool Opend => isOpen;
#endregion #region 方法
6.打开设备。 public void Open() { IntPtr device;//此处后续要用 uint hand = midiOutOpen(out device, 0, IntPtr.Zero, IntPtr.Zero, 0); isOpen = hand == 0; DeviceHandle = device; } /// <summary> /// 播放声音返回0表示成功！621表示设备未打开 /// </summary> /// <param name="msg"></param> /// <returns></returns> public uint Play(uint msg,int time)//播放，尝试了很多写法，发现msg * 256 + 0x00403B90;基本正常，百度百科的方法声音沙哑（msg*256+144+volume*655536+channel） { if (isOpen && DeviceHandle != IntPtr.Zero) { uint data = msg * 256 + 0x00403B90; Console.WriteLine(data); uint ms = midiOutShortMsg(DeviceHandle,data); System.Threading.Thread.Sleep(time); return msg; } else return 621; } public uint ChangeInstruments(MusicNo musicNo)//改变乐器 { return midiOutShortMsg(DeviceHandle, Convert.ToUInt32(192 + (uint)musicNo * 256)); } public void Close()//关闭设备 { uint msg = midiOutClose(DeviceHandle); } #endregion }
