Asp.net XML反序列化提供空WCF对象
我有一个XML字符串，比如Asp.net XML反序列化提供空WCF对象,asp.net,wcf,Asp.net,Wcf,我有一个XML字符串，比如 <?xml version="1.0"?> <FullServiceAddressCorrectionDelivery xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <AuthenticationInfo xmlns="http://www.usps.com/postalone/se
<?xml version="1.0"?>
<FullServiceAddressCorrectionDelivery xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<AuthenticationInfo xmlns="http://www.usps.com/postalone/services/UserAuthenticationSchema">
<UserId xmlns="">FAPushService</UserId>
<UserPassword xmlns="">Password4Now</UserPassword>
</AuthenticationInfo>
</FullServiceAddressCorrectionDelivery>
XmlSerializer xs = new XmlSerializer(typeof(FullServiceAddressCorrectionDelivery));
var result = (FullServiceAddressCorrectionDelivery)xs.Deserialize(stream);
DataContractSerializer xs = new DataContractSerializer(typeof(FullServiceAddressCorrectionDelivery));
var result = (FullServiceAddressCorrectionDelivery)xs.ReadObject(stream);
在RENE（StackOverFlow成员）的帮助下，我成功地反序列化了同一个项目中的类。。但是当我把它们转换成WCF数据合同时。。我遇到了那个问题。。。。。请告诉我我哪里做错了 根据您希望如何使用数据协定序列化程序（DCS）进行该输入，您可以这样做，也可以不这样做。DC中数据成员的名称空间由其所属合约的名称空间定义，除非它是根元素（在这种情况下，[DC]名称空间也定义了元素的名称空间） 根元素FullServiceAddressCorrectionDelivery在示例XML中有一个名称空间（空），其成员AuthenticationInfo有另一个名称空间(http://www.usps.com/postalone...). 这意味着，除非您实际更改序列化程序的创建方式，否则您将无法将DCS用于此类型 然而，XmlSerializer（XS）应该可以正常工作——该类型的成员可以有不同的名称空间。正如您在下面的代码中所看到的，我可以将您提供的XML逐字发布到一个操作，该操作将FullServiceAddressCorrectionDelivery作为输入，并且对象已正确填充-您需要使用[XmlSerializerFormat]属性标记该操作（或契约）以获得此行为
