Number of items in a List that contain the word "blue"?

Question

How do I cound the number of items in a List that contain the word 'blue'? List liststCarColors= new List (). Perhaps something similar to -> liststCarColors.FindAll('Blue')?

You can count the number of items in a List that contain the word "blue" using LINQ's Count method along with a lambda expression. For example: using System; using System.Collections.Generic; using System.Linq; class Program { static void Main(string[] args) { List listCarColors = new List () { "blue", "green", "blueish", "dark blue", "lightblue", "red" }; int count = listCarColors.Count(color => color.Contains("blue")); Console.WriteLine($"Number of items containing 'blue': {count}"); } }

Please check this one, Add linq reference, using System.Linq; List liststCarColors = new List { "red", "blue", "green", "blue", "yellow", "blue" }; var count = liststCarColors.Count(x => x.Contains("blue"));

using System; using System.Collections.Generic; using System.Linq; class Program { static void Main() { List carColors = new List { "blue car", "red car", "blue sky", "green car" }; int count = carColors.Count(color => color.Contains("blue")); Console.WriteLine(count); // This will output the count of items containing the word "blue" } }

If you are doing wildcard matching, then please use this snippet int count = itemList.Count(item => item.Contains("blue")); if you are looking exact match then please follow the below snippet int count = itemList.Count(item => item == "blue");
