如何在wp7的独立存储设置中存储多个数据？

Question

我想保存在隔离storage.And多个名字我用店里multopple存储这个代码

if (!setting.Contains("CityDetail")) 
      { 

        setting.Add("CityDetail", cityname); 

      } 
      else 
      { 
       setting["CityDetail"] = cityname; 


          } 
      setting.Save(); 

但它仅给出最后的附加值，H =那么，如何可以获取所有数据的基础上的价值？

您可以使用这些功能，你的对象存储在phoneapplication状态

public static void SaveState(string key, object value) 
    { 
     if (phoneApplicationPage.State.ContainsKey(key)) 
     { 
      phoneApplicationPage.State.Remove(key); 
     } 

     phoneApplicationPage.State.Add(key, value); 
    } 

    public static object LoadState(this PhoneApplicationPage phoneApplicationPage, string key) 
    { 
     if (phoneApplicationPage.State.ContainsKey(key)) 
     { 
      return phoneApplicationPage.State[key]; 
     } 

     return null; 
    } 

编辑，使用isolatedsettings

public void SaveCompositeObject() 
    { 
     var settings = IsolatedStorageSettings.ApplicationSettings; 
     Person person= new City { Name = "Alex", Age= "21" }; 
     settings.Add("person", person); 
    } 

    public class Person 
    { 
    public string Name 
    { 
     get; 
     set; 
    } 

    public string Age 
    { 
     get; 
     set; 
    } 
} 

检索数据

Person person1; 
settings.TryGetValue<Person>("person", out person11);
