DbGeometry.GeometryCollectionFromText(String, Int32) 方法

定义

创建基于指定已知文本值和坐标系统标识符 (SRID) 的新 DbGeometry 集合值。Creates a new DbGeometry collection value based on the specified well known text value and coordinate system identifier (SRID).

public:
 static System::Data::Spatial::DbGeometry ^ GeometryCollectionFromText(System::String ^ geometryCollectionWellKnownText, int coordinateSystemId);
public static System.Data.Spatial.DbGeometry GeometryCollectionFromText (string geometryCollectionWellKnownText, int coordinateSystemId);
static member GeometryCollectionFromText : string * int -> System.Data.Spatial.DbGeometry
Public Shared Function GeometryCollectionFromText (geometryCollectionWellKnownText As String, coordinateSystemId As Integer) As DbGeometry

参数

geometryCollectionWellKnownText
String

包含知名几何图形值的文本表示形式的字符串。A string that contains a well known text representation of the geometry value.

coordinateSystemId
Int32

新 DbGeometry 值应使用的坐标系的标识符。The identifier of the coordinate system that the new DbGeometry value should use.

返回

DbGeometry

通过指定坐标系统标识符由知名文本值定义的新的 DbGeometry 值。A new DbGeometry value as defined by the well known text value with the specified coordinate system identifier.

例外

geometryCollectionWellKnownText

coordinateSystemId
