I'm trying to make a program where i can write in a certain number to trigger multiple functions.
But I'm having trouble identifying when a certain number is used. For an example say i have the number "10" i would like to change it to a binary string(00001010) automatically using an algorithm of some-sort. After that i would like to know which bits are on and off so i can call different functions.

The term you are looking for is not "byte-form", it's "binary" or possibly "binary string".
Converting it is pretty easy:

C#

int i = 10;
Console.WriteLine(Convert.ToString(i, 2).PadLeft(8, '0'));

But you don't need to convert it to check bits:

C#

    int i = 10;
    for (int j = 7; j >= 0; j--)
        {
        Console.Write(BitValue(i, j));
        }
    Console.WriteLine();
    }
private int BitValue(int i, int bitNo)
    {
    return (i >> bitNo) & 1;
    }

Or even:

C#

    int i = 10;
    Console.WriteLine(Convert.ToString(i, 2).PadLeft(8, '0'));
    for (int j = 7; j >= 0; j--)
        {
        Console.Write(BitValue(i, j) ? '*' : '.');
        }
    Console.WriteLine();
    }
private bool BitValue(int i, int bitNo)
    {
    return (i & (1 << bitNo)) != 0;
    }
