Parameters

multiPolygonWellKnownText
Type: System.Data.Entity.Core.Common.CommandTrees.DbExpression

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

coordinateSystemId
Type: System.Data.Entity.Core.Common.CommandTrees.DbExpression

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

Return Value

Type: System.Data.Entity.Core.Common.CommandTrees.DbFunctionExpression

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