C#中如何打开wav文件

Answer 1

using System.Runtime.InteropServices;
class Play
{
[DllImport("WinMM.dll")]
public static extern bool PlaySound(string szSound, IntPtr hMod, PlaySoundFlags flags);

[Flags]
public enum PlaySoundFlags : int
{
SND_SYNC = 0x0000, /* play synchronously (default) */ //同步
SND_ASYNC = 0x0001, /* play asynchronously */ //异步
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 */
}

public static void PlayWav(string strPath)
{
PlaySound(strPath, IntPtr.Zero, PlaySoundFlags.SND_ASYNC);
}
}

报错了，如下所示：
Error:1 The type or namespace name 'IntPtr' could not be found (are you missing a using directive or an assembly reference?)
还有'FlagsAttribute'和'Flags'也是，我是新手，麻烦帮忙解决下，谢谢啦

追答

缺少命名空间
你加上 using System;
我就写一个System.Runtime.InteropServices; 是因为DllImport 需要这个命名空间

这回没错误了，但是比如说我要打开桌面上的1个wav文件，怎样运行你写的程序让它找到我要打开的文件呢？

追答

你把文件嵌入到Resources里面调用，或者是放到bin文件夹下面
比如文件名叫11.mav ，你把这个文件放到bin文件夹下面，然后在合适的时候加载就可以了
如下：
private void Form1_Load(object sender, EventArgs e)
{
Play.PlayWav("11.wav");
}
还有不明白的你直接HI我吧
