AutoCAD .NET: Iterate Through Layer Table

We need to iterate through the layer table of the current database from time to time. Here is some succinct and good code in C# to do so.

[CommandMethod("LayerIterator")]
public static void LayerIterator_Method()
{
    Database database = HostApplicationServices.WorkingDatabase;
    using (Transaction transaction = database.TransactionManager.StartTransaction())
    {
        SymbolTable symTable = (SymbolTable)transaction.GetObject(database.LayerTableId, OpenMode.ForRead);
        foreach (ObjectId id in symTable)
        {
            LayerTableRecord symbol = (LayerTableRecord)transaction.GetObject(id, OpenMode.ForRead);

            //TODO: Access to the symbol
            MgdAcApplication.DocumentManager.MdiActiveDocument.Editor.WriteMessage(string.Format("\nName: {0}", symbol.Name));
        }

        transaction.Commit();
    }
}

If the command is run, something like the following may be printed out to the command line window.
