SpatialEdmFunctions.GeometryFromBinary Method
Creates a DbFunctionExpression that invokes the canonical 'GeometryFromBinary' function.
Assembly: EntityFramework (in EntityFramework.dll)
Name | Description | |
---|---|---|
![]() ![]() | GeometryFromBinary(DbExpression) | Creates a DbFunctionExpression that invokes the canonical 'GeometryFromBinary' function with the specified argument, which must have a binary result type. The result type of the expression is Edm.Geometry. |
![]() ![]() | GeometryFromBinary(DbExpression, DbExpression) | Creates a DbFunctionExpression that invokes the canonical 'GeometryFromBinary' 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.Geometry. |
SpatialEdmFunctions.GeometryFromBinary Method (DbExpression)
Creates a DbFunctionExpression that invokes the canonical 'GeometryFromBinary' function with the specified argument, which must have a binary result type. The result type of the expression is Edm.Geometry.
public static DbFunctionExpression GeometryFromBinary( DbExpression wellKnownBinaryValue )
Parameters
- wellKnownBinaryValue
-
Type:
System.Data.Entity.Core.Common.CommandTrees.DbExpression
An expression that provides the well known binary representation of the geometry value.
Return Value
Type: System.Data.Entity.Core.Common.CommandTrees.DbFunctionExpressionA new DbFunctionExpression that returns a new geometry value based on the specified binary value.
SpatialEdmFunctions.GeometryFromBinary Method (DbExpression, DbExpression)
Creates a DbFunctionExpression that invokes the canonical 'GeometryFromBinary' 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.Geometry.
public static DbFunctionExpression GeometryFromBinary( DbExpression wellKnownBinaryValue, DbExpression coordinateSystemId )
Parameters
- wellKnownBinaryValue
-
Type:
System.Data.Entity.Core.Common.CommandTrees.DbExpression
An expression that provides the well known binary representation of the geometry value.
- coordinateSystemId
-
Type:
System.Data.Entity.Core.Common.CommandTrees.DbExpression
An expression that provides the coordinate system id (SRID) of the geometry value's coordinate system.
Return Value
Type: System.Data.Entity.Core.Common.CommandTrees.DbFunctionExpressionA new DbFunctionExpression that returns a new geometry value based on the specified values.
