在Windows应用商店应用中恢复状态时出现序列化错误 [英] Serialization error when restoring state in Windows Store App

问题描述

大家好，



尝试序列化我的应用程序数据时，在Windows应用商店应用中出现以下错误：

< pre lang =xml> {类型' MyObject '具有数据合同名称''不是预期的。考虑使用DataContractResolver或添加任何静态未知的类型已知类型的列表 - 例如，通过使用KnownTypeAttribute属性或将它们添加到传递给DataContractSerializer的已知类型列表。}

我已经尝试使用相关标签来装饰相关类，方法如下：

 [DataContract] 
  public   class  SimpleObject 
 {
 [DataMember] 
  private   string  _Name; 
 [DataMember] 
  public   string 名称
 {
  //  设置人名 
  set  {此 ._ Name =  value ; } 
  //  获取人名 
 获取 {返回 此 ._名称; } 
} 
 
} 
 

除此之外，在 SuspensionManager 类我将自定义对象显式添加到 SaveAsync（）中的 _knownTypes 列表中方法如下：

 _ knownTypes.Add（ typeof （SimpleObject）） ; 
 

但是，我仍然收到此错误。有没有人有任何建议？



在研究这个问题时我已经阅读了以下帖子：

提前感谢任何建议。



干杯，

编辑：



我找到了一篇很棒的文章（最后），有一个有用的例子。我已经调整了它，因此它在终止应用程序时执行序列化，但实际的序列化代码很干净，似乎运行良好。

Hello all,

When attempting to serialize my application data, in a Windows Store App I get the following error:

{"Type 'MyObject' with data contract name '' is not expected. Consider using a DataContractResolver or add any types not known statically to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding them to the list of known types passed to DataContractSerializer."}

I have already tried to decorate the class in question using the relevant tags, in the following way:

[DataContract]
public class SimpleObject
{
    [DataMember]
    private string _Name;
    [DataMember]
    public string Name
    {
        //set the person name
        set { this._Name = value; }
        //get the person name
        get { return this._Name; }
    }

}

As well as this, in the SuspensionManager class I explicitly added my custom object to the _knownTypes list inside the SaveAsync() method in the following way:

_knownTypes.Add(typeof(SimpleObject));

However, I am still getting this error. Does anyone have any suggestions?

While researching this problem I have read the following posts:

Storing something other than a string in SuspensionManager.SessionState

SerializationException serializing newtonsoft jobject with DataContractSerializer

Thanks in advance for any suggestions.

Cheers,

Larry


EDIT:

I have found a great article (finally) with a worked example. I''ve tweaked it so it performs the serialization on termination of the app but the actual serialization code is clean and seems to work well.

Example Metro app /WinRT: Serializing and deseralizing objects using XMLSerializer to StorageFile and LocalFolder using generics and async/await threading
