delphi - WSDL导入器，用于带有负数的枚举类型

Question

我使用了一个使用正号和负号来指示该Web服务调用是否成功的Web服务，如果不是，则这些数字指示错误的类型。使用WSDL导入器（在Delphi 2007，Delphi 2010和Delphi XE中），我得到以下类型定义：

PCRUpdateCodes =（_7，_6，_5，_4，_3，_2，_1，_1，_2，_3，_4）；

在WSDL中，右边的最后四个条目为负数。 Delphi编译器给我最后四个条目的错误“重新声明了标识符”。如何使最后四个条目为负数？

这是WSDL的相关部分。

    <xs:annotation>
       <xs:documentation>Codes to describe return codes for an attempted PCR import web service operation</xs:documentation>

Answer 1

我已尝试使用Delphi XE（更新1）提供的WsdlImp.exe 15.0.3953.35171定义枚举。选项“验证枚举成员”已选中。

这是生成的枚举的代码。

TEnumTest = (
        _7,
        _6,
        _5,
        _4,
        _3,
        _2,
        _1,
        _12,
        _22,
        _32,
        _42,
        _52,
        _62
);

并为枚举值注册代码。

RemClassRegistry.RegisterExternalPropName(TypeInfo(TEnumTest), '_7', '-7');
RemClassRegistry.RegisterExternalPropName(TypeInfo(TEnumTest), '_6', '-6');
RemClassRegistry.RegisterExternalPropName(TypeInfo(TEnumTest), '_5', '-5');
RemClassRegistry.RegisterExternalPropName(TypeInfo(TEnumTest), '_4', '-4');
RemClassRegistry.RegisterExternalPropName(TypeInfo(TEnumTest), '_3', '-3');
RemClassRegistry.RegisterExternalPropName(TypeInfo(TEnumTest), '_2', '-2');
RemClassRegistry.RegisterExternalPropName(TypeInfo(TEnumTest), '_1', '-1');
RemClassRegistry.RegisterExternalPropName(TypeInfo(TEnumTest), '_12', '1');
RemClassRegistry.RegisterExternalPropName(TypeInfo(TEnumTest), '_22', '2');
RemClassRegistry.RegisterExternalPropName(TypeInfo(TEnumTest), '_32', '3');
RemClassRegistry.RegisterExternalPropName(TypeInfo(TEnumTest), '_42', '4');
RemClassRegistry.RegisterExternalPropName(TypeInfo(TEnumTest), '_52', '5');
RemClassRegistry.RegisterExternalPropName(TypeInfo(TEnumTest), '_62', '6');

看起来对我来说还好。如果不明白，可能是因为您有较旧的WsdlImp.exe版本。不得已的方法是手动修改生成的代码。
