SpatialEdmFunctions.GeometryFromGml Method

Definition

Namespace:

System.Data.Common.CommandTrees.ExpressionBuilder.Spatial

Assembly:

System.Data.Entity.dll

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

Overloads

GeometryFromGml(DbExpression)	Creates a DbFunctionExpression that invokes the canonical 'GeometryFromGml' function with the specified argument, which must have a string result type. The result type of the expression is Edm.Geometry.
GeometryFromGml(DbExpression, DbExpression)	Creates a DbFunctionExpression that invokes the canonical 'GeometryFromGml' function with the specified arguments. geometryMarkup must have a string result type, while coordinateSystemId must have an integer numeric result type. The result type of the expression is Edm.Geometry.

GeometryFromGml(DbExpression)

Creates a DbFunctionExpression that invokes the canonical 'GeometryFromGml' function with the specified argument, which must have a string result type. The result type of the expression is Edm.Geometry.

 static System::Data::Common::CommandTrees::DbFunctionExpression ^ GeometryFromGml(System::Data::Common::CommandTrees::DbExpression ^ geometryMarkup);

public static System.Data.Common.CommandTrees.DbFunctionExpression GeometryFromGml (System.Data.Common.CommandTrees.DbExpression geometryMarkup);

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

Public Function GeometryFromGml (geometryMarkup As DbExpression) As DbFunctionExpression

Parameters

geometryMarkup

DbExpression

An expression that provides the Geography Markup Language (GML) representation of the geometry value.

Returns

DbFunctionExpression

A new DbFunctionExpression that returns a new geometry value based on the specified value with the default coordinate system id (SRID) of the underlying provider.

Exceptions

ArgumentNullException

geometryMarkup

ArgumentException

Public Function GeometryFromGml (geometryMarkup As DbExpression, coordinateSystemId As DbExpression) As DbFunctionExpression

Parameters

geometryMarkup

DbExpression

coordinateSystemId

DbExpression

An expression that provides the coordinate system id (SRID) of the geometry value's coordinate system.

Returns

DbFunctionExpression

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

Exceptions

ArgumentNullException
