SpatialEdmFunctions.GeometryFromBinary Method

 

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

Namespace:   System.Data.Entity.Core.Common.CommandTrees.ExpressionBuilder.Spatial
Assembly:  EntityFramework (in EntityFramework.dll)

NameDescription
System_CAPS_pubmethodSystem_CAPS_staticGeometryFromBinary(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.

System_CAPS_pubmethodSystem_CAPS_staticGeometryFromBinary(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.DbFunctionExpression

A 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.DbFunctionExpression

A new DbFunctionExpression that returns a new geometry value based on the specified values.
