C# Program to filter array elements based on a predicate

Set an array.

int[] arr = { 40, 42, 12, 83, 75, 40, 95 };

Use the Where clause and predicate to get elements above 50.

IEnumerable<int> myQuery = arr.AsQueryable() .Where((a, index) => a >= 50);

Let us see the complete code −

Example

 Live Demo

using System;
using System.Linq;
using System.Collections.Generic;

public class Demo {
   public static void Main() {
      int[] arr = { 40, 42, 12, 83, 75, 40, 95 };
      Console.WriteLine("Array:");
      foreach (int a in arr) {
         Console.WriteLine(a);
      }
      // getting elements above 70
      IEnumerable<int> myQuery = arr.AsQueryable() .Where((a, index) => a >= 50);
      Console.WriteLine("Elements above 50...:");
      foreach (int res in myQuery) {
         Console.WriteLine(res);
      }
   }
}

Output

Array:
40
42
12
83
75
40
95
Elements above 50...:
83
75
95
