C# Linq Where Method

The Where method filters an array of values based on a predicate.

Here, the predicate is checking for elements above 70.

Where((n, index) => n >= 70);

Example

 Live Demo

using System;
using System.Linq;
using System.Collections.Generic;
public class Demo {
   public static void Main() {
      int[] arr = { 10, 30, 20, 15, 90, 85, 40, 75 };
      Console.WriteLine("Array:");
      foreach (int a in arr)
      Console.WriteLine(a);
      // getting elements above 70
      IEnumerable myQuery = arr.AsQueryable().Where((n, index) => n >= 70);
      Console.WriteLine("Elements above 70...:");
      foreach (int res in myQuery)
      Console.WriteLine(res);
   }
}

Output

Array:
10
30
20
15
90
85
40
75
Elements above 70...:
