namespace MSTestProject { [TestClass] public class UnitTest1 { [TestMethod] public void Test() { var list = GetListDifference(); foreach (var item in list) { Console.WriteLine(item); } } public List string > GetListDifference() { var list1 = new List string > { "Watermelon" , "Apple" , "Mango" , "Guava" , "Banana" }; var list2 = new List string > { "Orange" , "Kiwi" , "Apple" , "Watermelon" }; var elements = new List string >(); foreach (var item1 in list1) { foreach (var item2 in list2) { if (item1 == item2) { elements.Add(item1); } } } if (elements.Count > 0) { foreach (var item in elements) { list1.Remove(item); list2.Remove(item); } } var result = new List string >(); result.AddRange(list1); result.AddRange(list2); return result; } } }

Try this public static void GetDiffValue( string [] array1, string [] array2) { for ( int i = 0; i { bool valueFound = false ; for ( int j = 0; j { if (array1[i] == array2[j]) valueFound = true ; } if (!valueFound) Console.WriteLine(array1[i]); } } static void Main( string [] args) { var array1 = new [] { "A" , "B" , "C" }; var array2 = new [] { "A" , "C" , "D" }; GetDiffValue(array1, array2); GetDiffValue(array2, array1); }

Try this var array1 = new [] { "A" , "B" , "C" }; var array2 = new [] { "A" , "C" , "D" }; var result = array2.Except(array1).Concat(array1.Except(array2));
