c# – Windows Phone 8 – 将列表保存到IsolatedStorage

我正在尝试保存一个类我的类对象的集合.我收到一个错误说明：

The collection data contract type ‘System.Collections.Generic.List cannot be deserialized because it does not have a public parameterless constructor.
Adding a public parameterless constructor will fix this error.

这是我的班级：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace MojProjekt
{
    class Lekarna
    {
        public string Ime { get; set; }

        public Lekarna()
        {
        }
    }
}

以下是我如何保存到IsolatedStorage：

List<Lekarna> lekarneList = new List<Lekarna>();  
// here I then fill the list ...  
IsolatedStorageSettings localStorage = IsolatedStorageSettings.ApplicationSettings;
localStorage.Add("lekarneList", lekarneList;
localStorage.Save();

解决方法:

把课程公之于众
