特殊字符XmlException和DataContractJsonSerializer

Question

I'm seeing XmlException occuring from the output whenever the JSON being deserialized contains characters like '@'. In the end, it still successfully deserializes it, but it bugs me not knowing what's going wrong. It also slows down debugging a lot as many of the json responses contais these characters.

Code to reproduce:

public static class JsonHelper
{     
    public static T Deserialize<T>(string json)
    {
        var obj = Activator.CreateInstance<T>();
        using (var ms = new MemoryStream(Encoding.UTF8.GetBytes(json)))
        {
            var serializer = new DataContractJsonSerializer(obj.GetType());
            obj = (T)serializer.ReadObject(ms);
        }
        return obj;
    }
}

[DataContract]
class JsonObject
{
    [DataMember(Name = "@name")]
    public string Name { get; set; }
}


public partial class MainPage : PhoneApplicationPage
{
    private static string json = "{\"@name\":\"Something\"}";

    // Constructor
    public MainPage()
    {
        InitializeComponent();

        var obj = JsonHelper.Deserialize<JsonObject>(json);
        // obj.Name now contains "Something" as it should, but an XmlException has also happened.
    }

An exception of type 'System.Xml.XmlException' occurred in System.Xml.ni.dll and wasn't handled before a managed/native boundary

Am I missing something? I wouldn't want to do any search&replace before deserializing, if possible.

Edit

If I run the same code in a .NET 4.5 console app, I don't see this exception happening.

Answer 1

Can you try wrapping the call to JsonHelper.Deserialize... in a try catch and checking the innerexception to see if there is more detail. Additionally, you might try setting the accessor of your JsonObject class to public and see if that helps.

Answer 2

开始使用json.NET ，它在处理此类响应方面没有任何问题。
