c#+ArcGIS Engine-获取矢量图层的空间参考

转自原文c#+ArcGIS Engine-获取矢量图层的空间参考

介绍一种简单的获取矢量图层空间参考的方法：
首先打开Shp文件获得FeatureClass，代码如下：

string pPath="D:\\test.shp";
string pFolder=Path.GetDirectoryName (pPath);
string pFileName=Path.GetFileName(pPath);
IWorkspace pWorkspace=pWorkspaceFactory .OpenFromFile(pFolder ,0); 
IFeatureWorkspace pFeatureWorkspace =pWorkspace as IFeatureWorkspace ;
IFeatureClass pFeatureClass=pFeatureWorkspace .OpenFeatureClass (pFileName ); 

然后 由FeatureClass得到空间参考，代码如下：

IGeoDataset pGeoDataset = (IGeoDataset)pFeatureClass;
ISpatialReference pSpatialReference = pGeoDataset.SpatialReference;
