SpatialEdmFunctions.GeometryMultiLineFromBinary 方法

定義

建立一個使用指定引數叫用標準 'GeometryMultiLineFromBinary' 函式的 DbFunctionExpressionmultiLineWellKnownBinaryValue 必須具有二進位結果型別,而 coordinateSystemId 必須具有整數數值結果型別。 運算式的結果型別為 Edm.Geometry。

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

參數

multiLineWellKnownBinaryValue
DbExpression

提供幾何多線值之已知二進位表示的運算式。

coordinateSystemId
DbExpression

運算式,提供幾何多線值座標系統的座標系統 ID (SRID)。

傳回

根據指定值傳回新幾何多線值的新 DbFunctionExpression。

例外狀況
