C＃XML反序列化错误（2,2）

Question

学校给了我一个XML文档，我必须在屏幕上显示信息。据我所知，Xml反序列化将是最简单/最好的解决方案。

我有这个至今：

public static List<Project> ProjectListDeserialize(string path) 
{ 
    XmlSerializer serializer = new XmlSerializer(typeof(List<Project>)); 
    Stream filestream = new FileStream(path, FileMode.Open); 
    return (List<Project>)serializer.Deserialize(filestream); 
} 

public static Projects ProjectsDeserialize(string path) 
{ 
    XmlSerializer serializer = new XmlSerializer(typeof(Projects)); 
    Stream filestream = new FileStream(path, FileMode.Open); 
    return (Projects)serializer.Deserialize(filestream); 
} 

这是XML文档的样子：

<?xml version="1.0" encoding="utf-16" ?>  
<Projects xmlns="http://www.pulse.nl/DynamicsAX/2009/DataSets" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> 
    <Project ID ="1000.0001" CustomerID="1000"> 
     <Name>Project data key performance indicators</Name> 
     <Status>WorkInProgress</Status> 
     <StartDate>2011-01-01</StartDate> 
     <ExpectedCompletionDate>2011-08-01</ExpectedCompletionDate> 
     <CompletionDate xsi:nil="true" /> 
    </Project> 
    <Project ID ="1000.0008" CustomerID="1000" ParentID="1000.0001"> 
     <Name>Implementation</Name> 
     <Status>WaitListed</Status> 
     <StartDate>2011-06-01</StartDate> 
     <ExpectedCompletionDate>2011-08-01</ExpectedCompletionDate> 
     <CompletionDate xsi:nil="true" /> 
    </Project> 
</Projects> 

两种方法都抛出同样的异常：

<Projects xmlns='http://www.pulse.nl/DynamicsAX/2009/DataSets was not expected 

如何我可以正确反序列化上面的XML吗？任何样本都会有帮助！

Answer 1

尝试指定default namespace为XML文档中的XmlSerializer的构造函数：

var serializer = new XmlSerializer(typeof(Projects), "http://www.pulse.nl/DynamicsAX/2009/DataSets"); 

相关资源：

或者，您可以使用XmlTypeAttribute设置适当的命名空间

• XmlSerializer Constructor
• XML namespace

Answer 2

最有可能的问题是，您没有指定正确的名称空间作为Project类的属性。

您可以告诉XmlSerializer在反序列化期间忽略名称空间（检查this answer）。

[XmlType(Namespace = "http://www.pulse.nl/DynamicsAX/2009/DataSets")] 
public class Project 
{ 
    ... 
}
