[C#] On Asp.Net Dropdown list

It's webforms.

[C#] Asp.Net Dropdown list

I know there's a better way to do this.

<select id="<%Response.Write(QuantityId); %>" onmousewheel="return(false);" name="<%Response.Write(QuantityId); %>"
	onchange="javascript:<%Response.Write(ChangeHandler); %>">
	<%
		for (int i = CanRemove ? 0 : 1; i <= 9; ++i)
		{
			string select = "";
			if (StartQuantity == i) {select = "selected=\"selected\"";}
			Response.Write(string.Format("\n<option value=\"{0}\" {1} >{0}</option>", i,select));			
		}
	%>
</select>

[C#] On Square Class

2009-05-28T13:40:16-07:00

It's part of a Nurikabe solver. RoomType generates a change event because A) changing the roomtype may cause the display to change and B) changing the roomtype causes some revalidation to occur (checking if the square has gained/lost association with other squares, checking for a subset of rule violations).

The Neighbors/FullNeighbors array store the neighbors of the square (FullNeighbors includes the square itself). It is initialized elsewhere...which may be inappropriate, itself.

There is a temptation to replace it with a struct just containing X/Y coordinates and hashcode (LayoutKind.Explicit to make it overlap the coordinates), and roomtype, but such a refactoring would be a hassle.

[C#] Square Class

A messy class that has grown random features :/

using System;
using System.Collections.Generic;
using System.Text;
