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

There are shorter ways of doing it like others have said, but you can also check each character until you encounter a second space yourself, then return the corresponding substring.

static string Extract(string str)
{
    bool end = false;
    int length = 0 ;
    foreach (char c in str)
    {
        if (c == ' ' && end == false)
        {
            end = true;
        }
        else if (c == ' ' && end == true)
        {
            break;
        }

        length++;
    }

    return str.Substring(0, length);
}
