Question

我正在为Windows Phone 8中的应用创建个人资料页面我需要store data每个配置文件所以我正在使用IsolatedStorage

IsolatedStorageSettings Profile = IsolatedStorageSettings.ApplicationSettings;

和Ofcourse List用于存储所有

List<IsolatedStorageSettings> Profiles = new List<IsolatedStorageSettings>();

现在问题是当我想添加个人资料到列表时每个配置文件必须具有不同的密钥

  Profile.Add("profile1", player); // "profile1" is the key of the first profile
  Profile.Save();
  Profiles.Add(Profile);

所以，如果用户想要添加我需要做的个人资料 Profile.Add("profile(CurrentIndex)",player);

就像：

“player1”“player2”“player3”。。 “playerN”

我如何编写完成所有这些功能的代码？

Answer 1

您不必使用List<IsolatedStorageSettings>，因为IsolatedStorageSettings提供了Dictionary<TKey, TValue>，可以将密钥值对存储在隔离存储中。

这是我的代码，我试一试，效果很好。

public void SavePlayer()
        {
            IsolatedStorageSettings profile = IsolatedStorageSettings.ApplicationSettings;

            string key = string.Format("player{0}", GetCurrentIndex());
            profile.Add(key, player);
            profile.Save();
        }

        public object GetPlayer(string Key)
        {
            object obj = null;

            IsolatedStorageSettings settings = IsolatedStorageSettings.ApplicationSettings;

            if (settings.Contains(Key))
            {
                obj = settings[Key];
            }

            return obj;
        }

        public int GetCurrentIndex()
        {
            int index = 1;

            IsolatedStorageSettings settings = IsolatedStorageSettings.ApplicationSettings;

            if (settings.Contains("CurrentIndex"))
            {
                index = (int)settings["CurrentIndex"];
                index++;
                settings["CurrentIndex"] = index;
            }
            else
            {
                settings.Add("CurrentIndex", (int)1);
            }

            settings.Save();

            return index;
        }

这可能会对你有所帮助。想一想如何实现你所尝试的。

public class Profile
{
public string Datakey{get; set;}
public ProfileData Data{get; set;}
}

public class ProfileData 
{
public string Name{get;set;}
//define all your profile properties
...
...

}

//Now in code


IsolatedStorageSettings ProfileSettings = IsolatedStorageSettings.ApplicationSettings;

List<Profile> ProfileList = new List<Profile>();

//Add data in ProfileList instead of IsolatedStorageSettings 

Profile profileData = new Profile();
ProfileData data = new ProfileData ();
//Add properties
data.Name ="PlayerOne";
.....
...
profileData.Datakey="PlayerOneKey";
profileData.Data = data;
ProfileList.Add(profileData);

ProfileSettings.Add("AllProfile",ProfileList);
ProfileSettings.Save();

//If you want save another profile in IsolatedStorageSettings
 if(ProfileSettings.Contains("AllProfile"))
    {
       List<Profile> ProfileList = ProfileSettings["AllProfile"] as  List<Profile> ();
       // Add new item in profileList
    }

使用不同的键声明IsolatedStorage对象
