SpatialEdmFunctions.GeometryPolygonFromText Method

Definition

Creates a DbFunctionExpression that invokes the canonical 'GeometryPolygonFromText' function with the specified arguments. polygonWellKnownText 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 ^ GeometryPolygonFromText(System::Data::Common::CommandTrees::DbExpression ^ polygonWellKnownText, System::Data::Common::CommandTrees::DbExpression ^ coordinateSystemId);
public static System.Data.Common.CommandTrees.DbFunctionExpression GeometryPolygonFromText (System.Data.Common.CommandTrees.DbExpression polygonWellKnownText, System.Data.Common.CommandTrees.DbExpression coordinateSystemId);
static member GeometryPolygonFromText : System.Data.Common.CommandTrees.DbExpression * System.Data.Common.CommandTrees.DbExpression -> System.Data.Common.CommandTrees.DbFunctionExpression
Public Function GeometryPolygonFromText (polygonWellKnownText As DbExpression, coordinateSystemId As DbExpression) As DbFunctionExpression

Parameters

polygonWellKnownText
DbExpression

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

coordinateSystemId
DbExpression

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

Returns

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

Exceptions

polygonWellKnownText coordinateSystemId

polygonWellKnownText coordinateSystemId
