Using LINQ to Find the Sum of a MultiDimensional Array

Here’s how to the find the sum of a multidimensional array using LINQ. This array has 3 rows and 2 columns:
C#

using System;
using System.Linq;

class Program{
static void Main(string[] args)
{
    try
    {
        var myArray = new int[,]
        {
            { 1, 2 },
            { 3, 4 },
            { 5, 6 }
        };
        var arrSum =
                    (from int val in myArray
                     select val)
                     .Sum();

        Console.WriteLine(arrSum);
        Console.ReadLine();
    }
    catch (Exception ex)
    {
        // handle ex
    }
}
}

VB.NET

Imports System
Imports System.Linq

Friend Class Program
Shared Sub Main(ByVal args() As String)
    Try
        Dim myArray = New Integer(, ) { { 1, 2 }, { 3, 4 }, { 5, 6 } }
        Dim arrSum = ( _
                From val As Integer In myArray _
                Select val).Sum()

        Console.WriteLine(arrSum)
        Console.ReadLine()
    Catch ex As Exception
        ' handle ex
    End Try
End Sub
End Class
