 static System::Data::Common::CommandTrees::DbFunctionExpression ^ GeographyMultiPolygonFromText(System::Data::Common::CommandTrees::DbExpression ^ multiPolygonWellKnownText, System::Data::Common::CommandTrees::DbExpression ^ coordinateSystemId);

public static System.Data.Common.CommandTrees.DbFunctionExpression GeographyMultiPolygonFromText (System.Data.Common.CommandTrees.DbExpression multiPolygonWellKnownText, System.Data.Common.CommandTrees.DbExpression coordinateSystemId);

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

Public Function GeographyMultiPolygonFromText (multiPolygonWellKnownText As DbExpression, coordinateSystemId As DbExpression) As DbFunctionExpression

Parameters

multiPolygonWellKnownText: DbExpression

An expression that provides the well known text representation of the geography multi-polygon value.

coordinateSystemId: DbExpression

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

Returns

DbFunctionExpression

A new DbFunctionExpression that returns a new geography multi-polygon value based on the specified values.
