SpatialEdmFunctions.GeometryCollectionFromText Method

Definition

Creates a DbFunctionExpression that invokes the canonical 'GeometryCollectionFromText' function with the specified arguments. geometryCollectionWellKnownText must have a string result type, while coordinateSystemId must have an integer numeric result type. The result type of the expression is Edm.Geometry.

public:
 static System::Data::Common::CommandTrees::DbFunctionExpression ^ GeometryCollectionFromText(System::Data::Common::CommandTrees::DbExpression ^ geometryCollectionWellKnownText, System::Data::Common::CommandTrees::DbExpression ^ coordinateSystemId);
public static System.Data.Common.CommandTrees.DbFunctionExpression GeometryCollectionFromText (System.Data.Common.CommandTrees.DbExpression geometryCollectionWellKnownText, System.Data.Common.CommandTrees.DbExpression coordinateSystemId);
static member GeometryCollectionFromText : System.Data.Common.CommandTrees.DbExpression * System.Data.Common.CommandTrees.DbExpression -> System.Data.Common.CommandTrees.DbFunctionExpression
Public Function GeometryCollectionFromText (geometryCollectionWellKnownText As DbExpression, coordinateSystemId As DbExpression) As DbFunctionExpression

Parameters

geometryCollectionWellKnownText
DbExpression

An expression that provides the well known text representation of the geometry collection value.

coordinateSystemId
DbExpression

An expression that provides the coordinate system id (SRID) of the geometry collection value's coordinate system.

Returns

A new DbFunctionExpression that returns a new geometry collection value based on the specified values.

Exceptions

geometryCollectionWellKnownText coordinateSystemId

geometryCollectionWellKnownText coordinateSystemId
