public static DbFunctionExpression GeographyFromBinary( DbExpression wellKnownBinaryValue )
Parameters
- wellKnownBinaryValue
-
Type:
System.Data.Entity.Core.Common.CommandTrees.DbExpression
An expression that provides the well known binary representation of the geography value.
Return Value
Type: System.Data.Entity.Core.Common.CommandTrees.DbFunctionExpressionA new DbFunctionExpression that returns a new geography value based on the specified binary value.
SpatialEdmFunctions.GeographyFromBinary Method (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.
