C # + AE load SHP, raster, and map document data

Steps:

1) create a workspace Factory

2) Open the shapefile workspace.

3) Open the element class

4) create a element layer

5) Associate layers and element classes

6) Add to map Space

Code (The following figure shows the corresponding steps ):

Iworkspacefactory pworkspacefactory = new shapefileworkspacefactory (); // 1

Openfiledialog1.filter = "shaperfile (*. SHP) | *. SHP ";

Openfiledialog1.initialdirectory = @ "E: \ test \ document and data \ data ";

Openfiledialog1.multiselect = false;

Dialogresult pdialogresult = openfiledialog1.showdialog ();

If (pdialogresult! = Dialogresult. OK)

Return;

String ppath = openfiledialog1. filename;

String pfolder = path. getdirectoryname (ppath );

String pfilename = path. getfilename (ppath );

Iworkspace pworkspace = pworkspacefactory. openfromfile (pfolder, 0); // 2

Ifeatureworkspace pfeatureworkspace = pworkspace as ifeatureworkspace;

Ifeatureclass PFC = pfeatureworkspace. openfeatureclass (pfilename); // 3

Ifeaturelayer pflayer = new featurelayerclass (); // 4

Pflayer. featureclass = PFC;

Pflayer. Name = PFC. aliasname; // 5

Ilayer player = pflayer as ilayer;

IMAP pmap = axmapcontrol1.map;

Pmap. addlayer (player); // 6

Axmapcontrol1.activeview. Refresh ();
