Hello Codeproject,

How would I converted

C#

[XmlIgnore]
public Block[,] _Blocks { get; set; }

To:

C#

public Block[] _Blocks { get; set; }

And back to:

C#

public Block[] _Blocks { get; set; }

,

I need this for my XML Serializer, because I need to save the list of blocks, but the XML serializer does not allow Multi-dimensional array.

Why do u need a XML serializer property? You can customize your own property.

What do you mean ?

I got this as a propery because that is how XML Serializer works, and I need to save this in a file and load it out later.

Can you specify your requirement more briefly?

I am not really sure how to explain it more briefly. I got an multi-dimensional array of a 'block' class, I need to be able to convert that into a single array so I can use the XML serializer to save it in a file. I just don't know how to convert a multi into a single array and back.

Here's some sample code of an int[] conversion if you don't have any specifications. NOTE: this only works with multi-dimensional array's with the same width and height...

C#

static int[,] SingleToMulti(int[] array)
{
     int index = 0;
     int sqrt = (int)Math.Sqrt(array.Length);
     int[,] multi = new int[sqrt, sqrt];
     for (int y = 0; y < sqrt; y++)
     {
        for (int x = 0; x < sqrt; x++)
        {
            multi[x, y] = array[index];
            index++;
        }
      }
      return multi;
}

C#

static int[] MultiToSingle(int[,] array)
{
     int index = 0;
     int width = array.GetLength(0);
     int height = array.GetLength(1);
     int[] single = new int[width * height];
     for (int y = 0; y < height; y++)
     {
         for (int x = 0; x < width; x++)
         {
            single[index] = array[x, y];
            index++;
         }
     }
     return single;
}
