创建一个 DbFunctionExpression ，该函数使用指定的参数调用规范“GeometryMultiPointFromBinary”函数。 multiPointWellKnownBinaryValue 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.Geometry。

public:
 static System::Data::Common::CommandTrees::DbFunctionExpression ^ GeometryMultiPointFromBinary(System::Data::Common::CommandTrees::DbExpression ^ multiPointWellKnownBinaryValue, System::Data::Common::CommandTrees::DbExpression ^ coordinateSystemId);

public static System.Data.Common.CommandTrees.DbFunctionExpression GeometryMultiPointFromBinary(System.Data.Common.CommandTrees.DbExpression multiPointWellKnownBinaryValue, System.Data.Common.CommandTrees.DbExpression coordinateSystemId);

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

Public Function GeometryMultiPointFromBinary (multiPointWellKnownBinaryValue As DbExpression, coordinateSystemId As DbExpression) As DbFunctionExpression
