推荐答案

就像评论所说的，您只需要获得一些可序列化的对象，并且您可以将其存储在 IS 中.请注意多维数组不可序列化！

Like the comments said all you need is to get some serializable object and you're able to store it in IS. Be awate that arrays of more than one dimension are not serializable!

这是我用于 IS 的代码块:

Here is a code chunk I use for IS:

using System.IO;
using System.IO.IsolatedStorage;
using System.Xml.Serialization;

namespace PhoneApp1
{
public class IsolatedStorage
{
    public static void SaveToIs(String fileName, Object saved)
    {
        try
        {
            using (IsolatedStorageFile isf = IsolatedStorageFile.GetUserStoreForApplication())
            {
                if (isf.FileExists(fileName))
                {
                    isf.DeleteFile(fileName);
                }


                using (IsolatedStorageFileStream fs = isf.CreateFile(fileName))
                {

                    XmlSerializer ser = new XmlSerializer(saved.GetType());
                    ser.Serialize(fs, saved);
                }
            }
        }
        catch (IsolatedStorageException ex)
        {
            MessageBox.Show(ex.Message);
        }


    }

    public static Object loadFromIS(String fileName, Type t)
    {
        Object result = null;
        try
        {
            using (IsolatedStorageFile isf = IsolatedStorageFile.GetUserStoreForApplication())
            {
                if (isf.FileExists(fileName))
                {

                    using (StreamReader sr = new StreamReader(isf.OpenFile(fileName, FileMode.Open)))
                    {
                        XmlSerializer ser = new XmlSerializer(t);
                        result = ser.Deserialize(sr);
                    }
                }
            }
        }
        catch (IsolatedStorageException ex)
        {
            MessageBox.Show(ex.Message);
        }
        catch (InvalidOperationException e)
        {
            MessageBox.Show(e.Message);
        }
        return result;
    }
}
}
