我正在与使用在Apache服务器上运行的Web服务的第三方合作。有些选项minOccurs =“0”的字段。我使用'add service reference ...'命令加载wsdl文件。在最终的cs文件中,minOccurs =“0”的字段未标记为可选。他们被视为普通班级成员。然后,当我在没有这些可选字段的情况下对返回的数据进行desearilize时,我将收到错误消息。我该如何解决这个问题?

答案 0 :(得分:0)
在查看原始返回数据后,我注意到有一个nil =“true”的数据字段。 .NET没有为此字段生成正确的代码文件。该类始终期望此字段的日期时间值。将字段定义更改为Nullable后,该服务运行良好。它不是一个理想的解决方案,每次更新服务时都必须手动执行。
