Does seem weird that formatting is not working. Try passing the values as an int instead of a string. That's the only thing that I could get to work.

CODE

int TestInt = 12;
Console.WriteLine("{0:000}",TestInt);


Good luck.

Hey there umeshshivakanth,

As SpiderSpartan pointed out this will only work with a number, not a string. You are trying to use numeric formatting on a string"{0:000}". So, just convert the string to an int first:

CODE

            sAc = String.Format("{0:000}", Convert.ToInt32(sAcNo1)).ToString();


Hope this helps,

Kitt
