SpatialEdmFunctions.GeometryFromGml Method
Creates a DbFunctionExpression that invokes the canonical 'GeometryFromGml' function.
Assembly: EntityFramework (in EntityFramework.dll)
Name | Description | |
---|---|---|
![]() ![]() | 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. |
SpatialEdmFunctions.GeometryFromGml Method (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.

Parameters
- geometryMarkup
-
Type:
System.Data.Entity.Core.Common.CommandTrees.DbExpression
An expression that provides the Geography Markup Language (GML) 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 value with the default coordinate system id (SRID) of the underlying provider.
SpatialEdmFunctions.GeometryFromGml Method (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.

-
Type:
System.Data.Entity.Core.Common.CommandTrees.DbExpression
An expression that provides the coordinate system id (SRID) of the geometry value's coordinate system.
