Solution 1

You could create a method for doing that, like in the next example:

C#

public int RoundInt(int number, int digits)
        {
            int factor = (int)Math.Pow(10, digits);
            //
            if (number / factor > 0)
            {
                double temp = Math.Round((double)number/ factor, 0);
                return (int)temp * factor;
            }
            else
            {
                return 0;
            }
        }

Then you could invoke it like in the next example:

C#

int result = RoundInt(123,567 , 3); //==> 124,000 !

Yes, your solution is using a single line of code, but you should put it into a function with params.

This is not working too. it is simply trimming the last 3 digits.

Solution 2

Very simply where X is your number :

C#

int result = (int)(Math.Ceiling((double)X / 1000) * 1000);
