C# Increment Numeric String

I have a static string:

static string SERIAL = "000";

I need to increment it by 1 on a certain condition. For example, the value should be like this:

001
002
003

and so on.

I have tried different ways but haven't been able to figure it out

You could have the serial value as a integer and define a getter which will return the value as a string in the desired format. This way you can simply increment the numeric value of the serial.

As an example:

public class Program
{
    static void Main(string[] args)
    {
        Console.WriteLine(Counter.SerialString);
        Counter.Serial++;
        Console.WriteLine(Counter.SerialString);
        Console.ReadKey();
    }

    public class Counter
    {
        public static int Serial;

        public static string SerialString
        {
            get
            {
                return Serial.ToString("000");
            }
        }
    }
}

One way would be to use the PadLeft method on the ToString method.

        int n = 000;
        for (int i = 0; i < 100; i++)
        {
            n++;
            Console.WriteLine(n.ToString().PadLeft(3, '0'));               
        }
        Console.ReadLine();

Heres the method header public string PadLeft(int totalWidth, char paddingChar);

If the serial is always 3 digit long, You can use an integer and when You need it as a string, just call its ToString() method.
