FeatureLayer 的架构， 并且必须包含一个类型为 oid 的字段； source 指定一个 Graphic 数组来表示 FeatureLayer 的数据， 如果没有数据， 则设置一个空数组； geometryType...FeatureSet ， 可以很方便的创建 FeatureLayer const featureLayer: __esri.FeatureLayer = new FeatureLayer({ geometryType...: featureSet.geometryType as any, fields: featureSet.fields, source: featureSet.features,...fields: [ { name: 'FID', type: 'oid' }, { name: 'Tree_ID', type: 'integer' } ], geometryType

解决办法： 在cpp文件下，删除DoDataExchange函数中的代码：DDX_Control(pDX, IDC_EDIT1, GeometryType); ? 再重新运行调试，错误解决！

-->GeometryType(g) 以字符串形式返回几何类型的名称，如POINT,LINESTRING -->IsClosed(g) 返回对象g是否封闭 -->
其他类型只要设置对应的type就可以了，比如绘制不规则多边形为POLYGON，具体类型可以查看文档：https://openlayers.org/en/latest/apidoc/module-ol_geom_GeometryType.html
