Creates a DbFunctionExpression that invokes the canonical 'GeographyPointFromBinary' function with the specified arguments. pointWellKnownBinaryValue 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 ^ GeographyPointFromBinary(System::Data::Common::CommandTrees::DbExpression ^ pointWellKnownBinaryValue, System::Data::Common::CommandTrees::DbExpression ^ coordinateSystemId);

public static System.Data.Common.CommandTrees.DbFunctionExpression GeographyPointFromBinary (System.Data.Common.CommandTrees.DbExpression pointWellKnownBinaryValue, System.Data.Common.CommandTrees.DbExpression coordinateSystemId);

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

Public Function GeographyPointFromBinary (pointWellKnownBinaryValue As DbExpression, coordinateSystemId As DbExpression) As DbFunctionExpression

Parameters

pointWellKnownBinaryValue: DbExpression

An expression that provides the well known binary representation of the geography point value.

coordinateSystemId: DbExpression

An expression that provides the coordinate system id (SRID) of the geography point value's coordinate systempointWellKnownBinaryValue.

Returns

DbFunctionExpression

A new DbFunctionExpression that returns a new geography point value based on the specified values.
