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：

点击[确定]，出现如下界面，点击[Next]。

接着，设置相关信息，并点击[finish]完成。

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.<esri.configuration xmlns="http://schemas.esri.com/Desktop/AddIns" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">02.<name>ArcMapAddinTest</name>03.<addinid>{0f7ec41b-d1e3-4391-8d67-9dea10bea621}</addinid>04.<description>Type in a description for this Add-in.</description>05.<version>1.0</version>06.<img src="" style="display: none;"><img alt="加载中..." title="图片加载中..."src="http://www.it165.net/statics/images/s_nopic.gif">ImagesArcMapAddinTest.png07.<author>Administrator</author>08.<company></company>09.<date>2013/12/12</date>10.<targets>11.<target name="Desktop" version="10.0">12.</target></targets>13.<addin language="CLR" library="ArcMapAddinTest.dll" namespace="ArcMapAddinTest">14.<arcmap>15.<commands><button caption="AddShp" category="Add-In Controls" class="AddShp" id="ArcMapAddinTest_AddShp"image="ImagesAddShp.png" message="点击浏览shp文件并添加" tip="实现添加shp文件的功能"></button></commands></arcmap></addin></esri.configuration>01.using System;02.using System.Collections.Generic;03.using System.Text;04.using System.IO;05. 06. 07.namespace ArcMapAddinTest08.{09.public class AddShp : ESRI.ArcGIS.Desktop.AddIns.Button10.{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 host35.//36.ArcMap.Application.CurrentTool = null;37.}
