Get Index of First non-Whitespace Character in C# String

Question

Is there a means to get the index of the first non-whitespace character in a string (or more generally, the index of the first character matching a condition) in C# without

Answer 1

There is a very simple solution

string test = "    hello world";
int pos = test.ToList().FindIndex(x => char.IsWhiteSpace(x) == false);

pos will be 4

you can have more complex conditions like:

pos = test.ToList().FindIndex((x) =>
                {
                    if (x == 's') //Your complex conditions go here
                        return true;
                    else 
                        return false;
                }
            );
