Array of Objects into Array

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

Simply use selectMany
var array = arrayOfArrays.SelectMany(item => item).Distinct().ToArray();
