新建 Maps 类
在同步类中，要用到 Maps 类，用于管理地图对象。与新建同步类 ControlsSynchronizer 类似，我们新建一 Maps 类，其所有 代码如下所示：
using System;
using System.Collections;
using System.Collections.Generic; using System.Text;
using System.Runtime.InteropServices; using ESRI.ArcGIS.Carto;
namespace _sdnMap {
[Guid(\ [ClassInterface(ClassInterfaceType.None)] [ProgId(\
public class Maps : IMaps, IDisposable {
//class member - using internally an ArrayList to manage the Maps collection
private ArrayList m_array = null; #region class constructor public Maps() {
m_array = new ArrayList(); }
#endregion
#region IDisposable Members
public void Dispose() {
if (m_array != null) { m_array.Clear(); m_array = null; } }
#endregion
#region IMaps Members
public void RemoveAt(int Index) {
if (Index > m_array.Count | Index < 0)
throw new Exception(\range!\
m_array.RemoveAt(Index); }
public void Reset() {
