SpatialEdmFunctions.GeometryCollectionFromBinary Method (DbExpression, DbExpression)
Creates a DbFunctionExpression that invokes the canonical 'GeometryCollectionFromBinary' function with the specified arguments. geometryCollectionWellKnownBinaryValue must have a binary result type, while coordinateSystemId must have an integer numeric result type. The result type of the expression is Edm.Geometry.
Assembly: EntityFramework (in EntityFramework.dll)
public static DbFunctionExpression GeometryCollectionFromBinary( DbExpression geometryCollectionWellKnownBinaryValue, DbExpression coordinateSystemId )
Parameters
- geometryCollectionWellKnownBinaryValue
-
Type:
System.Data.Entity.Core.Common.CommandTrees.DbExpression
An expression that provides the well known binary representation of the geometry collection value.
- coordinateSystemId
-
Type:
System.Data.Entity.Core.Common.CommandTrees.DbExpression
An expression that provides the coordinate system id (SRID) of the geometry collection value's coordinate system.
Return Value
Type: System.Data.Entity.Core.Common.CommandTrees.DbFunctionExpressionA new DbFunctionExpression that returns a new geometry collection value based on the specified values.
