C# Linq Except Method
Get the difference between two arrays using the Except() method.
The following are the two arrays.
int[] arr = { 9, 12, 15, 20, 35, 40, 55, 67, 88, 92 }; int[] arr2 = { 20, 35 };
To get the difference, use Except() method that returns the first list, except the elements in the second list.
arr.AsQueryable().Except(arr2);
The following is the entire example.
Example
using System; using System.Linq; using System.Collections.Generic; class Program { static void Main() { int[] arr = { 5, 10, 15, 20, 35, 40 }; int[] except = { 20, 35 }; Console.WriteLine("Initial List..."); foreach(int ele in arr) Console.WriteLine(ele); IEnumerable<int> res = arr.AsQueryable().Except(except); Console.WriteLine("New List..."); foreach (int a in res) Console.WriteLine(a); } }
Output
Initial List... 5 10 15 20 35 40 New List... 5 10 15 40
