创建一个 DbFunctionExpression ，它使用指定的参数调用规范“GeographyMultiPolygonFromBinary”函数。 multiPolygonWellKnownBinaryValue 必须具有二进制结果类型，而 coordinateSystemId 必须具有整数数值结果类型。表达式的结果类型为 Edm.Geography。

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
