Case-Insensitive List Search in C#

To search in list with case-Insensitive we can use Lambda expression which uses Equal() method and take second parameter as attribute: StringComparison.OrdinalIgnoreCase.

Make sure to include required namespaces: using System.Collections.Generic;, using System.Linq;.

Example

using System;
using System.Collections.Generic;
using System.Linq;
					
public class Program
{
	public static void Main()
	{
		List<string> myValues = new List<string>(new string[] { "hello", "uSers", "how", "aRe", "you" } );
		string keyword = "users";
		if( myValues.Any( s => s.Equals(keyword, StringComparison.OrdinalIgnoreCase) ) )
    		Console.WriteLine("found in list");
	}
}

Output

found in list
