C#学习笔记——简单的声音播放

现在正在做一个简单的C#软件，为了美化和多媒体的东西，我需要在窗体启动的时候播放音乐，查找了MSDN找到了这个东西，记录一下以后使用！

源码：

using System;
using System.Runtime.InteropServices;

namespace GIS
{
/// <summary>
/// CMedia 的摘要说明。
/// </summary>
internal class CSoundPlay
{
public CSoundPlay()
{
//
// TODO: 在此处添加构造函数逻辑
//
}

[Flags]
public enum PlaySoundFlags : int
{
SND_SYNC = 0x0000, /* play synchronously (default) */
SND_ASYNC = 0x0001, /* play asynchronously */
SND_NODEFAULT = 0x0002, /* silence (!default) if sound not found */
SND_MEMORY = 0x0004, /* pszSound points to a memory file */
SND_LOOP = 0x0008, /* loop the sound until next sndPlaySound */
SND_NOSTOP = 0x0010, /* don't stop any currently playing sound */
SND_NOWAIT = 0x00002000, /* don't wait if the driver is busy */
SND_ALIAS = 0x00010000, /* name is a registry alias */
SND_ALIAS_ID = 0x00110000, /* alias is a predefined ID */
SND_FILENAME = 0x00020000, /* name is file name */
SND_RESOURCE = 0x00040004 /* name is resource name or atom */
}

[DllImport("winmm.dll")]
public static extern bool PlaySound( string szSound, IntPtr hMod, PlaySoundFlags flags );

}

public class Sound
{
public static void Play( string strFileName )
{
CSoundPlay.PlaySound( strFileName, IntPtr.Zero, CSoundPlay.PlaySoundFlags.SND_FILENAME | CSoundPlay.PlaySoundFlags.SND_ASYNC );
}
}

}

1、添加上述代码到您的工程中；

2、调用：Sound.Play(SoundFilePathAndName);

说明：此方法必须保证你的机器上有winmm.dll文件，该文件的作用嘛！你可以上网查询一下！
