c#+AE实现查找一个图层中所选的polyline要素是否闭合

Question

思路是找到起终点坐标，判断两个点坐标值相等，但是不知道具体的实现算法和代码。

Answer 1

IFeatureLayer pFeatureLayer;

IFeatureClass pFeaterClass = pFeatureLayer.FeatureClass; string where = ""; IQueryFilter filter = new QueryFilterClass(); filter.WhereClause = where; IFeatureCursor pFeatcursor = pFeaterClass.Search(filter, false); IFeature pFeature = pFeatcursor.NextFeature(); while (pFeature!= null) { pFeature = pFeatcursor.NextFeature(); } }

能否帮到你？
