Convert binary string into integer

Question

I would like to convert a binary number writen in a String into its integer value.

For example:

string input = "0101";
int output = convert(input);

output should be equal to 5

@TimLloyd the other question is newer? If anything that question is a dupe of this :) — mhvelplund
