C# 怎么将int型转化成datetime型？parameterizedthreadstart

C#怎么将Int型转化成DateTime型？

PublicclassTime{staticvoidMain(){Threadth=newThread(newParameterizedThreadStart(starts))；inti=int.Parse(Console.ReadLine())；th.Start(i)；

}publicstaticvoidstarts(objecti){intp=int.Parse(i.ToString())；p=p*1000；while(p>；0){Console.WriteLine(p/1000/60+"；："；+p/1000%60+"；："；+p%100)；Thread.Sleep(1)；p--；}}}//C#时间转化
