SpatialEdmFunctions.GeographyLineFromText(DbExpression, DbExpression) Method

Definition

Creates a DbFunctionExpression that invokes the canonical 'GeographyLineFromText' function with the specified arguments. lineWellKnownText must have a string result type, while coordinateSystemId must have an integer numeric result type. The result type of the expression is Edm.Geography.

public:
 static System::Data::Common::CommandTrees::DbFunctionExpression ^ GeographyLineFromText(System::Data::Common::CommandTrees::DbExpression ^ lineWellKnownText, System::Data::Common::CommandTrees::DbExpression ^ coordinateSystemId);
public static System.Data.Common.CommandTrees.DbFunctionExpression GeographyLineFromText (System.Data.Common.CommandTrees.DbExpression lineWellKnownText, System.Data.Common.CommandTrees.DbExpression coordinateSystemId);
static member GeographyLineFromText : System.Data.Common.CommandTrees.DbExpression * System.Data.Common.CommandTrees.DbExpression -> System.Data.Common.CommandTrees.DbFunctionExpression
Public Function GeographyLineFromText (lineWellKnownText As DbExpression, coordinateSystemId As DbExpression) As DbFunctionExpression

Parameters

lineWellKnownText
DbExpression

An expression that provides the well known text representation of the geography line value.

coordinateSystemId
DbExpression

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

Returns

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

Exceptions

lineWellKnownText coordinateSystemId

lineWellKnownText coordinateSystemId
