You can use
Split()
method.
Have a look at the following
link[
^].
An example from the link;
string s = "there is a cat";
string[] words = s.Split(' ');
foreach (string word in words)
{
Console.WriteLine(word);
}
so in this case second word which is "is"=> you can find it in
words[1]
Adaptation to your code:
SelectExactMatch(words[1]);
Good luck,
