XML 反序列化仅适用于 xml 中的命名空间 [英] XML deserializing only works with namespace in xml

问题描述

让 ServiceStack xml 反序列化工作的最简单方法是当 xml 包含命名空间时.但是，我收到的 xml 不包含命名空间.最简单的工作示例:

The most simple way I get ServiceStack xml deserialization to work is when the xml contains a namespace. However, the xml I receive do not contain namespaces. The most simple working example:

[Serializable]
public class test
{

}

class Program
{
   static void Main(string[] args)
   {
       string xml="<test xmlns="http://schemas.datacontract.org/2004/07/"></test>";
       var result = ServiceStack.Text.XmlSerializer.DeserializeFromString<test>(xml);
   }
}

然而，这不是我想要的.我希望反序列化以下内容，因为这是我从多个服务中获得的 xml:

However, that is not what I want. I want the following to deserialize, since that is the xml I get from several services:

string xml="<test></test>";

但这给了我以下错误:

DeserializeDataContract: Error converting type: Error in line 1 position 7. 
Expecting element 'test' from namespace 
'http://schemas.datacontract.org/2004/07/'.. 
Encountered 'Element'  with name 'test', namespace ''.

我试过了:

[Serializable]
[XmlRoot("test", Namespace = "")]
public class test

我无法创建新的序列化器，因为 ServiceStack.Text.XmlSerializer 是静态的.我需要选择 Microsoft XmlSerializer 或 ServiceStack(不是两者).含义:如果我不能让这个简单的例子工作，我需要跳过 ServiceStack 包中一个非常有用的部分.我想要的最后一件事是在传入的 xml 中注入一些虚拟命名空间.

I can't create a new Serializer, because ServiceStack.Text.XmlSerializer is static. I need to choose for either Microsoft XmlSerializer OR ServiceStack (not both). Meaning: if I can't get this simple example to work I need to skip an otherwise very useful part of the ServiceStack package. The last thing I want is to inject some dummy namespace in the incoming xml.

推荐答案

ServiceStack 使用 .NET 的 Xml DataContractSerializer 来序列化 XML 以删除命名空间，您需要将命名空间设置为空字符串:

ServiceStack uses .NET's Xml DataContractSerializer to serialize XML to remove Namespaces you need to either set the Namespace to an empty string with:

[DataContract(Namespace="")]
public class test { ... }

但是，您必须使用 [DataMember] 属性标记要序列化的每个属性.更好的选择是通过在 Assembly.cs 文件中添加和 Assembly 属性来为 C# 命名空间下的所有类型指定一个空命名空间，例如:

But then you'll have to mark each property you want serialized with [DataMember] attributes. A better option is to specify an empty namespace for all types under a C# namespace by adding and Assembly attribute in your Assembly.cs file, e.g:

[assembly: ContractNamespace("", ClrNamespace = "MyServiceModel.DtoTypes")]

注意:您可以删除 [Serializable] 属性 - ServiceStack 的任何序列化程序都不会使用它.此外，像 [XmlRoot] 这样的所有 XmlSerializer 属性都是无用的，因为 ServiceStack 使用 .NET 的 DataContractSerializer 而不是 Microsoft 早期的 XmlSerializer.

Note: you can remove the [Serializable] attribute - it's not used by any of ServiceStack's serializers. Also all XmlSerializer attributes like [XmlRoot] are useless since ServiceStack uses .NET's DataContractSerializer not Microsoft's earlier XmlSerializer.
