  • Reference

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.

public:
 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

geometryMarkup
