Follow the code (works):

var teste = 1;
var teste1 = teste.ToString("000000");

Upshot:

000001

Follow another code (does not work):

var teste = "1";
var teste1 = teste.ToString("000000");

Upshot:

cannot Convert from 'string' to 'System.Iformatprovider'

How can I convert string for ToString with a result "000001"?

c# .net string

It makes no sense to convert string for string, already is string. Let alone you can convert string for ToString() which is a method and not a type.

If you want to put zeros in front of the number use the PadLeft().

using static System.Console;

public class Program {
    public static void Main() {
        var teste = "1";
        WriteLine(teste.PadLeft(6, '0'));
    }
}

Behold working in the ideone. And in the .NET Fiddle. Also put on the Github for future reference.
