Creates a DbFunctionExpression that invokes the canonical 'GeometryPolygonFromBinary' function with the specified arguments. polygonWellKnownBinaryValue must have a binary 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 ^ GeometryPolygonFromBinary(System::Data::Common::CommandTrees::DbExpression ^ polygonWellKnownBinaryValue, System::Data::Common::CommandTrees::DbExpression ^ coordinateSystemId);

public static System.Data.Common.CommandTrees.DbFunctionExpression GeometryPolygonFromBinary (System.Data.Common.CommandTrees.DbExpression polygonWellKnownBinaryValue, System.Data.Common.CommandTrees.DbExpression coordinateSystemId);

static member GeometryPolygonFromBinary : System.Data.Common.CommandTrees.DbExpression * System.Data.Common.CommandTrees.DbExpression -> System.Data.Common.CommandTrees.DbFunctionExpression

Public Function GeometryPolygonFromBinary (polygonWellKnownBinaryValue As DbExpression, coordinateSystemId As DbExpression) As DbFunctionExpression

Parameters

polygonWellKnownBinaryValue: DbExpression

An expression that provides the well known binary 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

DbFunctionExpression

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