使用XmlSerializerFormat

标签： c# wcf soap xml-serialization

我正在使用旧的soap服务基于WSDL编写WCF服务。我使用svcutil生成服务合同并进行了一些更改以匹配我托管它的网站，但是当我从测试客户端调用服务时，请求对象将以null形式出现。

服务返回的响应也被错误地序列化，我确信这是相关的。但我无法弄清楚为什么它没有正确序列化和反序列化。

这是服务合同：

        var settings = _settingService.LoadSetting<ApuSettings>(0);

        if (!string.Equals(request.header.account, settings.Username, StringComparison.InvariantCultureIgnoreCase))
            return false;

        if (!string.Equals(request.header.id, settings.Password))
            return false;

        return true;

答案 0 :(得分：1)

看起来Response是一个部分类。还有另一件，也许在另一个文件中吗？那是另一件可序列化的吗？ ResponseHeader和Part的相同问题？

我通常使用[Serializable]装饰器。

public float list课程Part上的关键字列表可能存在问题。

跟进：事实证明我最初发布的服务合同很好。这是错误的请求格式。解串器不是一个简单的内联xml结构，而是期待这个：

    </soapenv:Body>
</soapenv:Envelope>

在我们的客户记录客户发送的原始请求后，我想出了这一点。
