Assembly:

System.Data.Entity.dll

Creates a DbFunctionExpression that invokes the canonical 'GeographyFromBinary' function.

Overloads

GeographyFromBinary(DbExpression)	Creates a DbFunctionExpression that invokes the canonical 'GeographyFromBinary' function with the specified argument, which must have a binary result type. The result type of the expression is Edm.Geography.
GeographyFromBinary(DbExpression, DbExpression)	Creates a DbFunctionExpression that invokes the canonical 'GeographyFromBinary' function with the specified arguments. wellKnownBinaryValue must have a binary result type, while coordinateSystemId must have an integer numeric result type. The result type of the expression is Edm.Geography.

GeographyFromBinary(DbExpression)

Creates a DbFunctionExpression that invokes the canonical 'GeographyFromBinary' function with the specified argument, which must have a binary result type. The result type of the expression is Edm.Geography.

Public Function GeographyFromBinary (wellKnownBinaryValue As DbExpression) As DbFunctionExpression

Parameters

wellKnownBinaryValue

DbExpression

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

Returns

DbFunctionExpression
