How can I use ToString for it ?

Answer 1

If you just need to make int.ToString having sum leading zeros you can do it like this:

    int integer = 5;
    string str = integer.ToString("00"); // str has "05".

Answer 2

Assuming that x is a valid DateTime, this example works (9am appears as "09").

        DateTime x = DateTime.Now;

        string hours = x.AddHours(1).ToString("HH");
