法律研究如何在 C# 中通过控制台播放用户修改的蜂鸣声？
若要通过控制台播放用户修改的蜂鸣声，代码如下 −
示例
using System;
public class Demo {
public static void Main(String[] args){
Console.WriteLine("Displaying standard output stream...");
Console.WriteLine("Standard Output Stream = "+Console.Out);
Console.WriteLine("Beep sound through Console");
Console.Beep();
Console.WriteLine("Beep sound through Console with frequence 1000 hertz and duration 500 milliseconds");
Console.Beep(1000, 500);
}
}输出
这将产生以下输出 −
Displaying standard output stream... Standard Output Stream = System.IO.TextWriter+SyncTextWriter Beep sound through Console Beep sound through Console with frequence 1000 hertz and duration 500 milliseconds
示例
现在，我们来看另一个示例 −
using System;
public class Demo {
public static void Main(String[] args){
int freq = 1500;
int duration = 1000;
Console.WriteLine("Displaying standard output stream...");
Console.WriteLine("Standard Output Stream = "+Console.Out);
Console.WriteLine("Beep sound through Console");
Console.Beep();
Console.WriteLine("Beep sound through Console with frequency 1000 hertz and duration 500 milliseconds");
Console.Beep(1000, 500);
Console.WriteLine("Playing Beep sound 10 times...");
for (int i = 1; i < 10; i++)
Console.Beep(freq, duration);
}
}输出
这将产生以下输出 −
Displaying standard output stream... Standard Output Stream = System.IO.TextWriter+SyncTextWriter Beep sound through Console Beep sound through Console with frequency 1000 hertz and duration 500 milliseconds Playing Beep sound 10 times...
