问题描述

我正在尝试使用以下代码将对象列表序列化为XDocument，但是我收到一条错误消息，指出不能将非空格字符添加到内容中""

I'm trying to use the following code to serialize a list of objects into XDocument, but I'm getting an error stating that "Non white space characters cannot be added to content"

    public XDocument GetEngagement(MyApplication application)
    {
        ProxyClient client = new ProxyClient();
        List<Engagement> engs;
        List<Engagement> allEngs = new List<Engagement>();
        foreach (Applicant app in application.Applicants)
        {
            engs = new List<Engagement>();
            engs = client.GetEngagements("myConnString", app.SSN.ToString());
            allEngs.AddRange(engs);
        }

        DataContractSerializer ser = new DataContractSerializer(allEngs.GetType());

        StringBuilder sb = new StringBuilder();
        System.Xml.XmlWriterSettings xws = new System.Xml.XmlWriterSettings();
        xws.OmitXmlDeclaration = true;
        xws.Indent = true;

        using (System.Xml.XmlWriter xw = System.Xml.XmlWriter.Create(sb, xws))
        {
            ser.WriteObject(xw, allEngs);
        }

        return new XDocument(sb.ToString());
    }

我做错了什么?是XDocument构造函数不包含对象列表吗?该如何解决?

What am I doing wrong? Is it the XDocument constructor that doesn't take a list of objects? how do solve this?

推荐答案

我认为最后一行应该是

 return XDocument.Parse(sb.ToString());

完全切掉序列化器可能是一个主意，从List<>直接创建XDoc应该很容易.这样就可以完全控制结果.

And it might be an idea to cut out the serializer altogether, it should be easy to directly create an XDoc from the List<> . That gives you full control over the outcome.

大致:

var xDoc = new XDocument( new XElement("Engagements",
         from eng in allEngs
         select new XElement ("Engagement",
           new XAttribute("Name", eng.Name),
           new XElement("When", eng.When) )
    ));
