ArcEngine二次开发：esriJson与Geometry的相互转换

esriJson和Geometry的相互转换

• esriJson转Geometry Geometry转esriJson

esriJson转Geometry

json字符串：“{“spatialReference”:{“wkid”:4490},“rings”:[[[122,37.1],[123,37.2],[123,37.3],[122,37.4],[122,37.5],[122,37.1]]]}”——瞎编的

常用的esriGeometryType：esriGeometryPolygon、esriGeometryPoint、esriGeometryPolyline

public static ESRI.ArcGIS.Geometry.IGeometry ConvertToGeometry(string strJson, esriGeometryType type,
        bool bHasZ, bool bHasM)
        {
   
   
    		bool bHasZ=false;
    		bool bHasM=false;
            IJSONReader jsonReader = new JSONReaderClass();
            jsonReader.ReadFromString(strJson);

            JSONConverterGeometryClass jsonCon = new
