请教C#.net中类似beep()的方法

Question

如题

Answer 1

用aip,下面我貼出了實現部分的C#代碼using System.Runtime.InteropServices; //引入空間
namespace myBeep
{
public class Form1 : System.Windows.Forms.Form
{
[DllImport("kernel32.dll")]
public static extern bool Beep(int frequency, int duration);
public enum BeepType//這裡是api所需參數,產生不同的聲音頻率
{
　 SimpleBeep = -1,
　 IconAsterisk = 0x00000040,
　 IconExclamation = 0x00000030,
　 IconHand = 0x00000010,
　 IconQuestion = 0x00000020,
　 Ok = 0x00000000,
} 
[DllImport("user32.dll")]
public static extern bool MessageBeep(BeepType beepType); 
private void button1_Click(object sender, System.EventArgs e)
{
MessageBeep(BeepType.SimpleBeep ); 
System.Threading.Thread.Sleep(TimeSpan.FromSeconds(2));  
MessageBeep(BeepType.Ok); 
System.Threading.Thread.Sleep(TimeSpan.FromSeconds(2));
MessageBeep(BeepType.IconQuestion); 
System.Threading.Thread.Sleep(TimeSpan.FromSeconds(2));
MessageBeep(BeepType.IconHand ); 
System.Threading.Thread.Sleep(TimeSpan.FromSeconds(2));
MessageBeep(BeepType.IconExclamation); 
System.Threading.Thread.Sleep(TimeSpan.FromSeconds(2));
MessageBeep(BeepType.IconAsterisk  );  }
