SpatialEdmFunctions.GeographyMultiLineFromText 方法

定義

命名空間:

System.Data.Entity.Core.Common.CommandTrees.ExpressionBuilder.Spatial

組件:

EntityFramework.dll

建立一個使用指定引數叫用標準 'GeographyMultiLineFromText' 函式的 DbFunctionExpression。 multiLineWellKnownText 必須具有字串結果類型，而 coordinateSystemId 必須具有整數數值結果類型。 運算式的結果型別為 Edm.Geography。
