超圖SuperMap iObjects .NET Geometry轉geoJSON&WKT&WKB

關鍵代碼

var geoJSONTxt = Toolkit.GeometryToGeoJson(geometry);
var bytes = Toolkit.GeometryToWKB(geometry);
var wktTxt = Toolkit.GeometryToWKT(geometry);

SuperMap.Data.Toolkit中包含:

static byte[] GemetryToWKB(Geometry geometry);
static string GemetryToWKT(Geometry geometry);
Geometry GeoJsonToGeometry(string strGeoJson);
static void Geometry2ByteArray(Geometry geo, UGByteArray* arOutput);
static string GeometryToGeoJson(Geometry geometry);
static byte[] GeometryToWKB(Geometry geometry);
static string GeometryToWKT(Geometry geometry);
static PrjCoordSys PrjFromWKT(string wkt);
static string PrjToWKT(PrjCoordSys prj);
static Geometry WKBToGemetry(byte[] WKBDate);
static Geometry WKBToGeometry(byte[] WKBDate);
static Geometry WKTToGemetry(string strWKT);
static Geometry WKTToGeometry(string strWKT);

記住命名空間，查詢幫助文檔即可
