IPointCollection轉IPolyline

IPointCollection轉線IPolyline:

 IPolyline pl =   
 IPointCollection ptc = pl  
  missing = 
  ( i = ; i < num1; i++            IPoint pt = autoStation.GetFeature(i).Shape  IPoint;
  
  
 (pl  ITopologicalOperator).Simplify();

//把IPolyline插入到IFeatureClass中

 IFeatureClass f1 = (ws  IFeatureWorkspace).OpenFeatureClass( IFeature fea= fea.Shape = fea.Store();

自己總結一下，省的每次用的時候還得翻箱倒櫃。
