建立 DbFunctionExpression 一個，並以指定的參數呼叫典型的「GeographyMultiPolygonFromBinary」函式。 multiPolygonWellKnownBinaryValue 必須有二元結果型別，而 coordinateSystemId 必須有整數數值結果型別。該表達式的結果類型為 Edm.地理。

public:
 static System::Data::Common::CommandTrees::DbFunctionExpression ^ GeographyMultiPolygonFromBinary(System::Data::Common::CommandTrees::DbExpression ^ multiPolygonWellKnownBinaryValue, System::Data::Common::CommandTrees::DbExpression ^ coordinateSystemId);

public static System.Data.Common.CommandTrees.DbFunctionExpression GeographyMultiPolygonFromBinary(System.Data.Common.CommandTrees.DbExpression multiPolygonWellKnownBinaryValue, System.Data.Common.CommandTrees.DbExpression coordinateSystemId);

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

Public Function GeographyMultiPolygonFromBinary (multiPolygonWellKnownBinaryValue As DbExpression, coordinateSystemId As DbExpression) As DbFunctionExpression
