ArcgisEngine’s UnknownCoordinateSystem

arcgis engine. development, sometimes it does not confirm what the coordinate system, so the default setting an empty coordinate system. If you do not set shp file is created you will be prompted coordinate system creation failed. So empty a coordinate system on the coordinates is created is not clear for what data is necessary.

main code:


 UnknownCoordinateSystem system = new UnknownCoordinateSystem();
 ESRI.ArcGIS.Geometry.ISpatialReference spatialReference_Un = system as ESRI.ArcGIS.Geometry.ISpatialReference;
 spatialReference_Un.SetFalseOriginAndUnits(-180, -90, 1000000);//important code
