How do I extract a substring from a string until the second space is encountered?

Question

I have a string like this:

\"o1 1232.5467 1232.5467 1232.5467 1232.5467 1232.5467 1232.5467\"

How do I extract only \"o1 1232.5467\"?

Answer 1

I was thinking about this problem for my own code and even though I probably will end up using something simpler/faster, here's another Linq solution that's similar to one that @Francisco added.

I just like it because it reads the most like what you actually want to do: "Take chars while the resulting substring has fewer than 2 spaces."

string input = "o1 1232.5467 1232.5467 1232.5467 1232.5467 1232.5467 1232.5467";
var substring = input.TakeWhile((c0, index) => 
                                input.Substring(0, index + 1).Count(c => c == ' ') < 2);
string result = new String(substring.ToArray());
