C# Class De-initialization of Dynamic Memory

I am using a class that dynamically allocates an array during construction, as follows:

    class HeightMap
{
    private int width;
    private int height;
    private ulong numPixels;
    private float[,] value;

    public HeightMap(int width, int height)
    {
        if (width <= 0) throw new Exception("Invalid Dimension: Width");
        if (height <= 0) throw new Exception("Invalid Dimension: Height");

        // Make sure there is an uneven width and height (for allowing diamond square algorithm)
        if ((width % 2) == 0) width++;
        if ((height % 2) == 0) height++;

        this.numPixels = (ulong)(width * height);
        this.width = width;
        this.height = height;
        this.value = new float[width, height];
    }


}

Am I required to implement IDisposable to release the value array on destruction, or is this automatically handled when the object is invalidated? [Anything else possibly wrong with this method of allocation in the constructor?]

You need not Use IDisposable.They are generally used with Unmanaged Code.The Garbage Collector would take care of your Object Disposal.

You're allocating the memory through managed code. You don't need to worry about it.
