Convert string representation of binary number to int in C#

Question

I have a string of eight 1s and 0s with spaces in between, something like "1 0 0 1 1 0 1 0", that I want converted in to an int. Is there a simple way to do this? I feel like some kind of linq parsing would do it, but I don't even know what to do with the characters once I find them.

• Pete M: Just to clarify, the string 1 0 0 1 1 0 1 0 should be parsed as two, four bit values: 1001 and 1010. Then converted to hex. Correct?

Answer 1

You don't need any LINQ.
Convert.ToInt*() takes an optional fromBase parameter, which must be 2, 8, 10, or 16.

Convert.ToInt32("1 0 0 1 1 0 1 0".Replace(" ", ""), 2)

• MLavine: Well that makes this a very simple problem then hah. Thanks so much!

Answer 2

An alternative to @SLaks's answer (but only for parsing Hex) is

Int32.Parse(hexString, System.Globalization.NumberStyles.HexNumber);

There's no equivalent for binary, though, so his is a better general-purpose answer.
