C#, rotating 2D arrays

Question

I've looked at other post on rotating 2D arrays, but it's not quite what I want. I want something like this

 int[,] original= new int[4,2]
       {
           {1,2},
           {5,6},
           {9,10},
           {13,14}
       };

I want to turn it like this, rotatedArray = { {1,5,9,13}, {2,6,10,14}}; I want to do some analysis by column, as opposed to by rows.

This works, but is there an easier way??

 private static int[,] RotateArray(int[,] myArray)
  {
        int org_rows = myArray.GetLength(0);
        int org_cols = myArray.GetLength(1);

        int[,] myRotate = new int[org_cols, org_rows];

        for (int i = 0; i < org_rows; i++)
        {
            for(int j = 0; j < org_cols; j++)
            {
                myRotate[j, i] = myArray[i, j];
            }
        }

        return myRotate;
    }

Is there an easy way to iterate through columns in c#?

If you change your array to be an array of arrays it gets easier. I found this if you change it to an int[][]:

int[][] original = new[]
                                   {
                                       new int[] {1, 2},
                                       new int[] {5, 6},
                                       new int[] {9, 10},
                                       new int[] {13, 14}
                                   };

and the rotate method:

private static int[][] Rotate(int[][] input)
{
    int length = input[0].Length;
    int[][] retVal = new int[length][];
    for(int x = 0; x < length; x++)
    {
        retVal[x] = input.Select(p => p[x]).ToArray();
    }
    return retVal;
}
