How to find a line in a text using LINQ

Question

I am trying to filter one line in a text that meets the search criteria.

string item = items.Where(i => i.Contains("lemon")).ToList();

I am using LINQ, and do get the following error

error CS0029: Cannot implicitly convert type 'System.Collections.Generic.List<string>' to 'string'

Why do I get this error and how can I solve this ?

Answer 1

Your query returns a list of string, you won't be able to assign it to a string.

Try using LINQ's First method instead:

string item = items.First(i => i.Contains("lemon"));

I hope this helps :)

(oops I misread the question, I thought you needed one line that matched)

Answer 2

You cant assign list to string..
So string item = .. for list Is error.
Use list instead
List<string> item = items.Where(i => i.Contains("lemon")).ToList();

Answer 3

Yes, thank you. I do understand it.

I changed my code.

With First I can get the first occurance

With Where and String.Join, I can get all occurances if I want to and make a concatenated string.
