AE中使用Geoprocessor 的clip处理输出矢量数据

Geoprocessor gp = new Geoprocessor();
gp.OverwriteOutput = true;
IFeatureLayer inputfeaturelayer = pMap.get_Layer(0) as IFeatureLayer;
IFeatureLayer cliplayer = pMap.get_Layer(1) as IFeatureLayer;
IFeatureClass inputfeatureclass = inputfeaturelayer.FeatureClass;
IFeatureClass clipfeatureclass = cliplayer.FeatureClass;
IDataset dataset = inputfeatureclass as IDataset;
IWorkspace workspace = dataset.Workspace;
IFeatureWorkspace fworkspace = workspace as IFeatureWorkspace;
IFields outfields = inputfeatureclass.Fields;
IFeatureClass outfeatureclass = fworkspace.CreateFeatureClass("Clip_result", outfields, null, null, esriFeatureType.esriFTSimple, "Shape", "");

ESRI.ArcGIS.AnalysisTools.Clip clipTool =
new ESRI.ArcGIS.AnalysisTools.Clip(inputfeatureclass, clipfeatureclass, outfeatureclass);

gp.Execute(clipTool, null);
IFeatureLayer outlayer = new FeatureLayerClass();
outlayer.FeatureClass = outfeatureclass;
outlayer.Name = outfeatureclass.AliasName;
pMap.AddLayer((ILayer)outlayer);

axMapControlMain.ActiveView.Refresh();
