How to convert Decimal to binary C# (4 bits) [duplicate]

Question

i want to convert Decimal numbers to binary, Currently I'm using this way

private string strtoBin(string input)
{
    int number = Convert.ToInt32(input) ;
    string res = Convert.ToString(number, 2);

    return res;
}

it's working but when I'm having for example "6" I'm getting 110 instead of 0110? Any tips?!

"6" I'm getting 110 instead of 0110 Why not 00000110 or ... — Hamlet Hakobyan

Simple string modification:

string res = Convert.ToString(number, 2);
res = new string('0', 8 - res.Length) + res;
