A better sleep method than Thread.Sleep in C sharp

Sleep.CS:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Runtime.InteropServices;
using System.Windows.Forms;

namespace TimerNoCpuConsume
{
    class Timer
    {
        public delegate void TimerCompleteDelegate();

        [DllImport("kernel32.dll")]
        static extern IntPtr CreateWaitableTimer(IntPtr lpTimerAttributes, bool bManualReset, string lpTimerName);

        [DllImport("kernel32.dll")]
        static extern bool SetWaitableTimer(IntPtr hTimer, [In] ref long ft, int lPeriod, TimerCompleteDelegate pfnCompletionRoutine, IntPtr pArgToCompletionRoutine, bool fResume);

        [DllImport("kernel32.dll", SetLastError = true, CallingConvention = CallingConvention.Winapi, CharSet = CharSet.Auto)]
        [return: MarshalAs(UnmanagedType.Bool)]
        static extern bool CloseHandle(IntPtr hObject);

        [DllImport("User32.dll")]
        static extern int MsgWaitForMultipleObjects(int nCount, ref IntPtr handle, bool fWaitAll, int dwMilliseconds, int dwWakeMask);


        /// <summary>
        /// No occupation of cpu, the window does not get stuck, does not affect other code execution
        /// </summary>
        /// <param name="time">mill seconds</param>
        public static bool Sleep(int time)
        {
            TimerCompleteDelegate TimerComplete = new TimerCompleteDelegate(TimerCompleted);
            long Interval = -10 * time * 1000;//占8字节
            //Create of the timer
            IntPtr handle = CreateWaitableTimer(IntPtr.Zero, true, "WaitableTimer");
            SetWaitableTimer(handle, ref Interval, 0, TimerComplete, IntPtr.Zero, true);
            //wait for message
           
            while (MsgWaitForMultipleObjects(1, ref handle, false, -1, 255) != 0)
            {
                
                Application.DoEvents();
            }
            return CloseHandle(handle);
        }
        private static void TimerCompleted()
        {
            // Once the timer expires, the routine is executed. This is performed by a program implemented independently of the class that called the OnTimeRebug event.
        }

    }
}


Calling the method:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Threading;

namespace TimerNoCpuConsume
{
    class Program
    {
        static void Main(string[] args)
        {            
            Timer.Sleep(30000);
            Console.WriteLine("Done!");
            Console.Read();
        }
    }
}

Simmons Will not use the three-pointer as a conventional weapon, it is difficult to shoot like Curry Soup.

Since entering the league, Ben Simmons's physical condition, athleticism, vision and off-season offense are top-notch, but only shots have been criticized. In the first two seasons of his career, Simmons made a total of 17 shots from three-pointers. In 0, when he is shooting on the outside, the opponent can make a "please" gesture at will. But even if he is not good at shooting, Simmons is still selected for the All-Star team last season. If he gets a shooting skill package? The prospects of Simmons are undoubtedly limitless. This summer, Simmons has been polishing his jumper under the guidance of trainer Chris Johnson. From some streaming videos, he can see that his three-point jumper has improved. In the preseason game against Guangzhou, Simmons hit the first three-pointer in his career, and in the subsequent game against the Hornets, he made a mid-range jumper. It seems that Simmons seems to have more confidence in his jump shot, and he is more willing to sho...

The noise of the pelicans competing for the fish and the exclamation of the onlookers crowded into one, the atmosphere was warm. A clever pelican s...
