SpatialEdmFunctions.GeometryMultiPolygonFromBinary 方法

定義

建立 DbFunctionExpression 一個,並呼叫典型的「GeometryMultiPolygonFromBinary」函式,並附上指定的參數。 multiPolygonWellKnownBinaryValue 必須有二元結果型別,而 coordinateSystemId 必須有整數數值結果型別。 表達式的結果類型為Edm.Geometry。

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

參數

multiPolygonWellKnownBinaryValue
DbExpression

一個表達式,提供眾所周知的幾何多邊形值二進位表示。

coordinateSystemId
DbExpression

一個表示式,提供幾何多邊形值座標系的座標系 id(SRID)。

傳回

一個新的 DbFunctionExpression,根據指定的值回傳新的幾何多邊形值。

例外狀況
