Creates a DbFunctionExpression that invokes the canonical 'GeographyPolygonFromBinary' 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.Geography.
public:
static System::Data::Common::CommandTrees::DbFunctionExpression ^ GeographyPolygonFromBinary(System::Data::Common::CommandTrees::DbExpression ^ polygonWellKnownBinaryValue, System::Data::Common::CommandTrees::DbExpression ^ coordinateSystemId);
public static System.Data.Common.CommandTrees.DbFunctionExpression GeographyPolygonFromBinary (System.Data.Common.CommandTrees.DbExpression polygonWellKnownBinaryValue, System.Data.Common.CommandTrees.DbExpression coordinateSystemId);
static member GeographyPolygonFromBinary : System.Data.Common.CommandTrees.DbExpression * System.Data.Common.CommandTrees.DbExpression -> System.Data.Common.CommandTrees.DbFunctionExpression
Public Function GeographyPolygonFromBinary (polygonWellKnownBinaryValue As DbExpression, coordinateSystemId As DbExpression) As DbFunctionExpression
Parameters
- polygonWellKnownBinaryValue
- DbExpression
An expression that provides the well known binary representation of the geography polygon value.
- coordinateSystemId
- DbExpression
An expression that provides the coordinate system id (SRID) of the geography polygon value's coordinate system.
Returns
A new DbFunctionExpression that returns a new geography polygon value based on the specified values.
Exceptions
