C# 独立存储-如何读取附加数据

我有一个

游戏应用程序（WP8）

，在那里我们保存了多个攻击的分数并将其显示给用户

我有一个对象，其字段为noOfStonesPicked和noOfFruitsPicked

这是我的密码：

MyTopic topicObj = new MyTopic ();

for (int i = 0; i <= 2; i++)
            {
                Test mt = new Test();
                mt.noOfStonesPicked = 12;
                mt.noOfFruitsPicked= 20;
                topicObj.Stats.Add(mt);
                }                

WritetestTopicState(topicObj);

现在如何检索这些值并显示

编辑

这就是我尝试过的：

public static MyTopic ReadMockTestTopicState()
        {
            MyTopic topic = null;
            try
            {
                using (IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForApplication())
                {
                    // Read application settings. 
                    if (isoStore.FileExists("11.xml"))
                    {
                        using (var store = IsolatedStorageFile.GetUserStoreForApplication())
                        {
                            using (StreamReader SR = new StreamReader(store.OpenFile("12.xml", FileMode.Open, FileAccess.Read)))
                            {
                                XmlSerializer serializer = new XmlSerializer(typeof(MyTopic));
                                topic = (MyTopic)serializer.Deserialize(SR);
                                serializer = null;
                            }
                        }
                    }
                    else
                    {
                        // If setting does not exists return default setting.
                        topic = new MyTopic();
                    }
                }
            }
            catch (Exception)
            {
                throw;
            }
            return topic;
        }

这对于反序列化来说应该足够了，如果您的

MyTopic

对象可以正确序列化，我的意思是如果MyTopic对象的属性可以正确地用于xml序列化。

请参阅我的编辑，我已经尝试过了，第一次运行时，它将存储并检索3个值，下次运行时，它会抛出一个错误，

意外的XML声明

。这意味着您的MyTopic对象中存在一些问题。对于xml序列化，MyTopic对象的属性可能没有正确的属性。

public static MyTopic ReadMockTestTopicState()
        {
            MyTopic topic = null;
            try
            {
                using (IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForApplication())
                {
                    // Read application settings. 
                    if (isoStore.FileExists("11.xml"))
                    {
                        using (var store = IsolatedStorageFile.GetUserStoreForApplication())
                        {
                            using (StreamReader SR = new StreamReader(store.OpenFile("12.xml", FileMode.Open, FileAccess.Read)))
                            {
                                XmlSerializer serializer = new XmlSerializer(typeof(MyTopic));
                                topic = (MyTopic)serializer.Deserialize(SR);
                                serializer = null;
                            }
                        }
                    }
                    else
                    {
                        // If setting does not exists return default setting.
                        topic = new MyTopic();
                    }
                }
            }
            catch (Exception)
            {
                throw;
            }
            return topic;
        }

XmlSerializer serializer = new XmlSerializer(typeof(MyTopic));

StreamReader reader = new StreamReader(path);
_myTopic = (MyTopic)serializer.Deserialize(reader);
reader.Close();
