Answer 1

try it

int input = Convert.ToInt32("1700");
string result = String.Format("{0:##,##}", input);

Or that

Console.WriteLine(1700.ToString("##,##", new NumberFormatInfo() { NumberGroupSeparator = "'" })); 

Answer 2

var numformat = new NumberFormatInfo {
                   NumberGroupSeparator = "'",
                   NumberGroupSizes = new int[] { 3 },
                   NumberDecimalSeparator = "."
                };
Console.WriteLine(1000000.ToString("N",numformat));

Answer 3

:

Console.WriteLine(1000000.ToString("#,##0").Replace(
    CultureInfo.CurrentCulture.NumberFormat.NumberGroupSeparator, "'"));

NumberFormatInfo likeInMath = new NumberFormatInfo()
{
    NumberGroupSeparator = "'"
};
Console.WriteLine(1000000.ToString("#,##0", likeInMath));
