ArcgisAdd-In开发入门实例

1、开发环境

Vs2012+Arcgis10.2+win7 64bit

2、实现代码

首先在VS2012中新建一个解决方案,命名AddInTest。

接着,给解决方案AddInTest新建一个项目:

data-cke-saved-src=http://www.it165.net/uploadfile/files/2013/1212/20131212200241315.jpg

点击[确定],出现如下界面,点击[Next]。

data-cke-saved-src=http://www.it165.net/uploadfile/files/2013/1212/20131212200241316.jpg

接着,设置相关信息,并点击[finish]完成。

data-cke-saved-src=http://www.it165.net/uploadfile/files/2013/1212/20131212200243319.jpg

上图中,class name是类的名称,caption是button显示的文字,category是所属的command的分类,tooltip是鼠标在上面时状态栏显示的文字,description是工具的描述。

项目建成后,文件组织如下图:

将项目的框架改为framework 4.5

Config.esriaddinx是一个XML文件,是一个配置文件,里面包含了项目的相关配置,是自动生成的,内容如下:

01.using System;
02.using System.Collections.Generic;
03.using System.Text;
04.using System.IO;
05. 
06. 
07.namespace ArcMapAddinTest
08.{
09.public class AddShp : ESRI.ArcGIS.Desktop.AddIns.Button
10.{
11.public AddShp()
12.{
13.}
14. 
15.protected override void OnClick()
16.{
17.}
18. 
19.protected override void OnUpdate()
20.{
21.}
22.}
23.}


里面包含两个方法,onclick和onupdate方法。onclick方法是点击按钮时,我们在里面写添加shp文件的代码。

 

首先,添加如下引用:

 

1.using System.Windows.Forms;
2.using ESRI.ArcGIS.ArcMapUI;
3.using ESRI.ArcGIS.Carto;
4.using ESRI.ArcGIS.Geometry;
5.using ESRI.ArcGIS.Geodatabase;
6.using ESRI.ArcGIS.DataSourcesFile;


onclick方法里,事件的实现代码如下:

 

 

01.IMxDocument pMxd;
02.public Button1()
03.{
04.pMxd = ArcMap.Document as IMxDocument;
05.}
06. 
07.protected override void OnClick()
08.{           
09.System.Windows.Forms.OpenFileDialog openFileDialog = new System.Windows.Forms.OpenFileDialog();
10.openFileDialog.Filter = "shp(*.shp)|*.shp";
11.openFileDialog.InitialDirectory = @"D:";
12.openFileDialog.Multiselect = false;
13.DialogResult pDialogResult = openFileDialog.ShowDialog();
14.if (pDialogResult != DialogResult.OK)
15.{
16.return;
17.}
18.string pPath = openFileDialog.FileName;
19.string pFolder = System.IO.Path.GetDirectoryName(pPath);
20.string pFileName = System.IO.Path.GetFileName(pPath);
21. 
22.IWorkspaceFactory pWorkspaceFactory = new ShapefileWorkspaceFactory();
23.IWorkspace pWorkspace = pWorkspaceFactory.OpenFromFile(pFolder, 0);
24.IFeatureWorkspace pFeatureWorkspace = pWorkspace as IFeatureWorkspace;
25.IFeatureClass pFC = pFeatureWorkspace.OpenFeatureClass(pFileName);
26.IFeatureLayer pFLayer = new FeatureLayerClass();
27.pFLayer.FeatureClass = pFC;
28.pFLayer.Name = pFC.AliasName;
29.ILayer pLayer = pFLayer as ILayer;
30.IMap pMap = pMxd.FocusMap;
31.pMap.AddLayer(pLayer);
32. 
33.//
34.//  TODO: Sample code showing how to access button host
35.//
36.ArcMap.Application.CurrentTool = null;
37.}


OnUpdate方法事件的代码如下:

 

 

1.protected override void OnUpdate()
2.{
3.Enabled = pMxd.FocusMap.LayerCount >= 0;
4.}


代码编写完成后,编译程序,打开编译目录,编译文件如下:

双击.esriAddIn文件,添加工具到Arcmap中。打开Arcmap,打开扩展管理,command选项卡,找到Add-In Controls,这时候你会发现你编写的工具会出现在这一组里面。

点击[close],点点试试……
