Hi Amith, I am showing you two methods to achieve this. Hope this will help you. using System; using System.Collections.Generic; namespace Test { class Program { static void Main( string [] args) { Object[] arrA = { 1,2,3}; Object[] arrB = { "Kirtesh" , "Amith" , "Nitya" , "Mahesh" }; Console.WriteLine( "First Method :" + String.Join( "," , ConcateObjects(arrA, arrB))); Console.WriteLine( "Second Method :" + String.Join( "," , CopyObjects(arrA, arrB))); Console.ReadLine(); } private static object [] ConcateObjects( object [] firstArr, object [] secondArr) { if (firstArr == null ) { throw new ArgumentNullException(nameof(firstArr)); } if (secondArr == null ) { throw new ArgumentNullException(nameof(secondArr)); } List object > list = new List object >(firstArr); list.AddRange(secondArr); return list.ToArray(); } private static object [] CopyObjects( object [] firstArr, object [] secondArr) { if (firstArr == null ) { throw new ArgumentNullException(nameof(firstArr)); } if (secondArr == null ) { throw new ArgumentNullException(nameof(secondArr)); } object [] result = new object [firstArr.Length + secondArr.Length]; firstArr.CopyTo(result, 0); secondArr.CopyTo(result, firstArr.Length); return result; } } } Output Hoe this will help. Thanks
