copied!<p>How about basing something on <code>Dictionary<System.Drawing.Point, string></code>? So that you can write;</p> <pre><code>stringGrid.Add(new Point(3,4), "Hello, World!"); </code></pre> <p>Create a class containing such a dictionary and then you get what you're looking for, almost for free. Something like (untested)</p> <pre><code>class StringGrid { Dictionary<System.Drawing.Point, string> grid; public StringGrid { this.grid = new Dictionary<System.Drawing.Point, string>(); } public string Get(int x, int y) { string result = null; grid.TryGetValue(new Point(x,y), out result); return result; } public void Set(int x, int y, string content) { var pos = new Point(x,y); if (grid.ContainsKey(pos)) { if (content == null) { // no content, so just clear the cell. grid.remove(pos); } else { // add new content grid[pos].Value = content; } } else if (content != null) { // new non-null content grid.add(pos, content); } } } </code></pre> <p>EDIT: Also, if you want to get really flash;</p> <ul> <li>replace the dictionary with a <code>SortedList<,></code></li> <li>replace <code>System.Drawing.Point</code> with your own struct which implements <code>IComparable</code></li> </ul> <p>This way, the list would be internally ordered by row, then by column, making a simple <code>foreach</code> loop sufficient to iterate through all the values in the first row, then the values in the second, and so on. Allows you to convert to and `IEnumerable`` -- or a collection of rows.</p>
