arcgis engine设置数据源路径_arcgis engine中几种常用数据的加载方法

一、shp文件的加载：

IWorkspaceFactory pWorkspaceFactory;

IFeatureWorkspace pFeatureWorkspace;

IFeatureLayer pFeatureLayer;

//获取当前路径和文件名

OpenFileDialog dlg=new OpenFileDialog();

dlg.ShowDialog();

string strFullPath=dlg.FileName;

if(strFullPath=="") return;

int Index=strFullPath.LastIndexOf("//");

string filePath=strFullPath.Substring(0,Index);

string fileName=strFullPath.Substring(Index+1);

//打开工作空间并添加shp文件

pWorkspaceFactory=new

ShapefileWorkspaceFactoryClass();

//注意此处的路径是不能带文件名的

pFeatureWorkspace=(IFeatureWorkspace)pWorkspaceFactory.OpenFromFile(filePath,0);

pFeatureLayer=new FeatureLayerClass();

//注意这里的文件名是不能带路径的

pFeatureLayer.FeatureClass=pFeatureWorkspace.OpenFeatureClass(fileName);

pFeatureLayer.Name =

pFeatureLayer.FeatureClass.AliasName;

axMapControl1.Map.AddLayer(pFeatureLayer);</
