这两天写的一段简单代码,目的是从源shp（点）里提取属 这两天写的一段简单代码，目的是从源shp(点)里提取属性，包括点X,Y坐标。 然后再结合别的属性在目的shp里添加这个要素。因为要提取多个属性，所以用 了个结构数组来做中转。 ///

/// 从源SHP提取属性,结合数据库数据在目的SHP里添加新要素 ///

/// 源shp /// 目的shp public void AddPoint(ILayer ly,ILayer lyNew) { //声明变量 IFeatureLayer Fly = (IFeatureLayer)ly; IFeatureClass Fcls = Fly.FeatureClass; //获取原字段索引 int indexCode=Fcls.FindField("Stcdt"); int indexName=Fcls.FindField("Stnm"); int fNum=Fcls.FeatureCount(null); IFeatureCursor Fcsor = Fcls.Search(null,false); IFeature F = Fcsor.NextFeature(); //源字段属性赋值到结构数组 Riverstation[] pStation =new Riverstation[fNum-1]; for (int i = 0; i < fNum - 1; i++) { pStation[i].X = F.Shape.Envelope.LowerLeft.X; pStation[i].Y = F.Shape.Envelope.LowerLeft.Y; pStation[i].Code = F.get_Value(indexCode).ToString(); pStation[i].Name = F.get_Value(indexName).ToString(); pStation[i].Level = RiverBase.GetWaterLevel();//数据库 取值函数 F = Fcsor.NextFeature(); } //结构数组写入新图层(创建要素) IFeatureLayer FlyNew=(IFeatureLayer)lyNew; IFeatureClass FclsNew=FlyNew.FeatureClass; IFeatureCursor FcsorNew = FclsNew.Insert(true); IFeatureBuffer Fbuf = FclsNew.CreateFeatureBuffer(); //获取目的字段索引 int iCode = FclsNew.FindField("Code"); int iName = FclsNew.FindField("Name"); int iLevel = FclsNew.FindField("Level"); for (int i = 0; i < fNum - 1;i++ ) { IPoint pt = new PointClass(); IGeometry shape = pt; pt.X = pStation[i].X; pt.Y = pStation[i].Y; Fbuf.Shape = shape; //设置字段值 Fbuf.set_Value(iCode,pStation[i].Code); Fbuf.set_Value(iName,pStation[i].Name); Fbuf.set_Value(iLevel, pStation[i].Level); } //更新到FeatureClass FcsorNew.Flush(); }
