What is the function of the sleep function in C#?

In C#, the purpose of the Sleep function is to pause the current thread for a specified amount of time. It can be used to control the speed of program execution or to implement simple timing functions.

The Sleep function takes a time parameter in milliseconds, indicating the length of time the execution will pause. After calling the Sleep function, the current thread will enter a sleeping state, pause execution for the specified time, and then continue to execute subsequent code. In other words, the Sleep function will block the current thread until the specified time has passed.

Here is an example utilizing the Sleep function:

using System;
using System.Threading;

public class Program
{
    public static void Main()
    {
        Console.WriteLine("开始执行");
        
        // 暂停执行500毫秒
        Thread.Sleep(500);
        
        Console.WriteLine("500毫秒过去了");
        
        // 暂停执行1秒
        Thread.Sleep(1000);
        
        Console.WriteLine("1秒过去了");
        
        Console.WriteLine("执行完毕");
    }
}

Output:

开始执行
500毫秒过去了
1秒过去了
执行完毕

In the above example, calling the Sleep function pauses the program execution for 500 milliseconds and 1 second. This simulates a certain delay, allowing the program to run at the desired speed.
