Hexadecimal Loops in C#

Question

My goal was to get a 3DES password and for that im missing the last 6 digits.

for (int i = 0; i <= 16777215; i++)
{
    string hexValue = i.ToString("X").PadLeft(6, '0');
}

Answer 1

You could just get the maximum number in your set of hexadecimals which goes from [0,FFFFFF] in decimal the set goes from [0, 16777215]

for(int i = 0; i <= 16777215; i++) {
  string hexValue = i.ToString("X");
  // your logic goes here...
}

Answer 2

This should do it:

var allHexadecimals = Enumerable.Range(0, 0xFFFFFF + 1)
                                .Select(i => i.ToString("X").PadLeft(6, '0'));

Answer 3

You can actually convert directly to Hex from c#, check out this article:

https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/types/how-to-convert-between-hexadecimal-strings-and-numeric-types

e.g. for(int i = 0x0; i < 0xff;i+=0x01) {Console.WriteLine(iConsole.WriteLine(value.ToString("X"));}
