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"

namespace ArcMapAddinTest
08.
{
09.
public
class
AddShp : ESRI.ArcGIS.Desktop.AddIns.Button
10.
{

public
AddShp()

void
OnClick()

{

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……
