How do I select tokens from a string using LINQ?

Question

I want to select a token out of a string if it exists in the string, I've got as far the following but I'm unsure why it doesn't compile:

IList<string> tokens = _animals.Split(';');

Func<string, bool> f1 = str => str.Contains("Dog");
Func<string, Func<string, bool>, string> f2 = str => Equals(f1, true);

var selected = tokens.Select(f2);

Cheers

Answer 1

Do you really need LINQ to do that? Why can you do something like this:

_animals.Contains("Dog")

Answer 2

I think you just want this.

var selected = tokens.Where(str => str.Contains("Dog"));

Answer 3

Or in words

var selected = from token in tokens where token.Contains("Dog") select token;

Answer 4

try this

    var result = (from p in tokens where p.Contains("Dog") select p);
