c# - easy and fast way to convert an int to binary?

Question

What I am looking for is something like PHPs decbin function in C#. That function converts decimals to its representation as a string.

For example, when using decbin(21) it returns 10101 as result.

I found this function which basically does what I want, but maybe there is a better / faster way?

Answer 1

var result = Convert.ToString(number, 2);

– Almost the only use for the (otherwise useless) Convert class.
