反序列化SOAP响应空或无效的日期元素 [英] Deserializing SOAP-response with empty or invalid date element
问题描述
我耗费了SAP-NetWeaver的网络服务。响应对象包含一个数据，并且在未设置则返回0000-00-00。这导致了反序列化错误在我的.NET 4.0的WCF代理，因为用于.NET的最低有效日期将是0001-01-01。
I am consuming a SAP-NetWeaver web-service. The response object contains a data and when it is not set it returns "0000-00-00". This leads to a deserialization error in my .NET 4.0 WCF proxy because the minimum valid date for .NET would be "0001-01-01".
我问SAP开发者来装饰用的minOccurs =0属性的日期元素，而忽略它，如果没有价值present但他说他不能这样做。
I asked the SAP-developer to decorate the date element with the minoccurs="0" attribute and omit it if there's no value present but he states he can't do so.
在我要求他返回0001-01-01空日期 - 只为我的WCF代理 - 我想知道：
Before I ask him to return "0001-01-01" for empty dates - just for my WCF proxy - I would like to know:
-
是0000-00-00的SOAP方面的有效日期？找不到它的任何SOAP规范，所以请让我知道你的信息来源。
Is "0000-00-00" a valid date in terms of SOAP? Couldn't find it in any SOAP specification so please let me know your source of information.
有没有办法告诉.NET解串器接受0000-00-00，处理像DateTime.MinValue？
Is there a way to tell the .NET deserializer to accept "0000-00-00" and handle it like DateTime.MinValue?
非常感谢！
更新： 现在，SAP-web服务返回一个空的元素，如果日期为null。但我的问题是一样的。
UPDATE: Now the SAP-web-service returns an empty element if the date is null. But my problem remains the same.
推荐答案
有这个一个很好的谈话

也可以简单地实现定制去序列化的类。这样的0000-00-00的值会被逮住，并转化为DateTime.MinValue。 UPD：这是code我一直在谈论
it is possible to simply implement custom de serialisation of the class. so that the values of "0000-00-00" would be catched and converted into DateTime.MinValue. UPD: this is the code I've been talking about.
[OnDeserializing]
void OnDeserializing(StreamingContext c)
{
if (MyCustonObj == null)
{
MyCustonObj = new MyCustomClass();
MyCustonObj.MyStrData = "Overridden in deserializing";
}
}
