SoundPlayer player = new SoundPlayer();

Can you tell me what i am doing wrong..!!

回答1:

Try this:

SoundPlayer player = new SoundPlayer(Properties.Resources.ding);
player.Play();

You can also try this:

using System;
using System.Runtime.InteropServices;
using System.Resources;
using System.IO;
namespace Win32
{
  public class Winmm
  {
    public const UInt32 SND_ASYNC = 1;
    public const UInt32 SND_MEMORY = 4;

    [DllImport("Winmm.dll")]
    public static extern bool PlaySound(byte[] data, IntPtr hMod, UInt32 dwFlags);
    public Winmm() { }
    public static void PlayWavResource(string wav)
    {
      // get the namespace 
      string strNameSpace= 
        System.Reflection.Assembly.GetExecutingAssembly().GetName().Name.ToString();

      // get the resource into a stream
      Stream str = 
        System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream(      strNameSpace +"."+ wav );
      if ( str == null ) return;
     // bring stream into a byte array
     byte[] bStr = new Byte[str.Length];
     str.Read(bStr, 0, (int)str.Length);
     // play the resource
     PlaySound(bStr, IntPtr.Zero, SND_ASYNC | SND_MEMORY);
    }
  }
}

I think you have to ensure that the file is loaded before you play it.

SoundPlayer player = new SoundPlayer(Properties.Resources.ding);
player.Load();
player.Play();

I think you need to do more than that. Check out this article.
