How can I search for whole word in LINQ?
If I am searching for a word "car" in a list of strings {"carpenter","car repair","carrying","car workshop"} etc. And the result should be "car repair" & "car workshop" only .
I tries the below code
List<string> _tags = (from item in string_array
where item.ToLower().Contains(search_term)
select item).ToList();
But, contains always return similar words and I found this link on SO Linq Regex for whole word search which is not providing a complete answer using Regx.
So, anyone can help to write an answer in Regx or is any other options to use with Linq.

Try this:
var result = items.Where(i => i.Split(' ').Any(word => word.ToLower() == "car")).ToList();
If you need to take into account commas, you can use this instead:
var reg = new Regex("\\bcar\\b", RegexOptions.IgnoreCase);
var items = new [] { "carpenter", "car repair", "carrying", "car workshop", "car, repair", "car. repair", "car,repair" };
var result = items.Where(word => reg.IsMatch(word)).ToList();
Gives:
car repair
car workshop
car, repair
car. repair
car,repair
list.Where(item=>item.Split(' ').Contains("car"));
You can do the following:
string.Split()Contains using StringComaparer overload like:
string[] string_array = {"carpenter", "car repair", "carrying", "car workshop"};
string word = "car";
List<string> _tags = string_array.Where(r => r.Split()
.Contains(word, StringComparer.InvariantCultureIgnoreCase))
.ToList();
For output:
foreach (var item in _tags)
{
Console.WriteLine(item);
}
Output would be:
car repair
car workshop
