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.

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

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

Exceptions

ArgumentNullException

wellKnownBinaryValue

ArgumentException
