一个有关MessageBeep的问题
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices;

namespace 喇叭响
{
public partial class Form1 : Form
{
[DllImport("user32.dll")]
public static extern bool MessageBeep(uint uType);

public Form1()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)
{

MessageBeep(1);

}
}
}
窗体上就是一个按钮，怎么运行后点击按钮不发出声音啊?这是为什么？messagebeep到底怎么使用啊？
最好把运行后可以发出声音的代码压缩包发到我邮箱里，谢谢！邮箱：467503768@qq.com

[解决办法]

C# code

using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;using System.Runtime.InteropServices;namespace 喇叭响{  public partial class Form1 : Form  {    public enum BeepType    {      SimpleBeep = -1,      IconAsterisk = 0x00000040,      IconExclamation = 0x00000030,      IconHand = 0x00000010,      IconQuestion = 0x00000020,      Ok = 0x00000000,    }  [DllImport("user32.dll")]  public static extern bool MessageBeep(BeepType beepType);   public Form1()  {     InitializeComponent();  }  private void button1_Click(object sender, EventArgs e)  {     MessageBeep(BeepType.SimpleBeep);   } }}
[解决办法]
C# code
    //使用MessageBeep(unit uType):需添加 using System.Runtime.InteropServices;　　 public const int MB_ICONEXCLAMATION = 48;　　 [DllImport("user32.dll")]　　 public static extern bool MessageBeep(uint uType);　　 MessageBeep( MB_ICONEXCLAMATION );

//使用MessageBeep(unit uType):需添加 using System.Runtime.InteropServices;
public const int MB_ICONEXCLAMATION = 48;
[DllImport("user32.dll")]
public static extern bool Messa……

其实非常简单。
C# code
  Console.Beep();//这一句就可以搞定了。
