C#+AE不同shp文件要素的复制

C#+AE做的一个DEMO，实现了在不同shp文件下要素的复制，其中shp文件要素属性格式相同。

开发环境：VS2010+ArcObject10.1

功能介绍：首先，窗体加载的时候，加载数据AsiaCities_new.shp和AsiaCities_old.shp。

　　　　　点击按钮，执行复制的过程。即筛选AsiaCities_old.shp中POPULATION = 0的所有要素，然后复制到AsiaCities_new.shp中，复制之前先判断复制后　　　　　　的文件中是否已存在复制的要素，如已存在则不复制，如不存在则复制。

代码如下：

  1 using System;
  2 using System.Collections.Generic;
  3 using System.ComponentModel;
  4 using System.Data;
  5 using System.Drawing;
  6 using System.Linq;
  7 using System.Text;
  8 using System.Windows.Forms;
  9 using ESRI.ArcGIS.Carto;
 10 using ESRI.ArcGIS.Geodatabase;
 11 using ESRI.ArcGIS.Geometry;
 12 using ESRI.ArcGIS.Display;
