Try this:
using System; using System.Threading;
class Program {     static void Main()     {         Random rand = new Random();         int number = rand.Next(1, 1000); // 1 to 999         Console.WriteLine("The number is {0}", number);         int sum = 0;         for(int i = 1; i         Thread.Sleep(1000); // wait a second          Console.WriteLine("The sum of the numbers from 1 to {0} is  {1}", number, sum);          Console.ReadKey();     } }
