2D-array as a class property - how to create them the C# way?
<p>I am trying to create a class with a property that is a two-dimensional array. The array will hold various x,y coordinates on a grid (e.g. 0,1 or 3,7) and the size of the array is dependent on a class property called size.</p>

<p>How would you go about creating this array in C#? I have given my solution below, but having very little C# experience and coming from a Python background with some javascript knowledge, it feels like that there is a better solution to this problem. </p>

<p>Could one of you C# wizards enlighten me, please?</p>

<p>Thanks in advance for your help.</p>

<p>Here is my code:</p>

<pre><code>public class Obj
{
    int Size;  // Defines length of array
    int[,] Pos;

    // constructor
    public Obj(int size)
    {
        this.Size = size;
        this.Pos = new int[size, 2];
    }

    public void set_coord(int index, int x, int y)
    {
        if (index &gt;= this.Size) {
            Console.WriteLine("Catch OutOfRangeException");
        }
        else
        {
            this.Pos[index, 0] = x;
            this.Pos[index, 1] = y;
        }
    }
</code></pre>
