Int to string conversion with leading 0s


I currently convert an integer to a string for display to the screen, but wish to maintain 4 digits - i.e 10 = "0010". What is the best way of going from an integer of 10 to a string of "0010"?

This is in C# and .NET 4.

Cheers!


Solution

  • int num = 1;
    // pad with 0 up to 4 places
    string str = num.ToString("D4");
