反序列化列表 <Object> C＃

Question

I want to assign the List<Object> I recieve from this method to a new List<MyClass>

    public List<Object> Deserialize(string path)
    {
        IFormatter seri = new BinaryFormatter();

        Stream str = new FileStream(path, FileMode.Open, FileAccess.Read);
        List<Object> Lista = (List<Object>)(seri.Deserialize(str));
        str.Close();
        return Lista;
    }

My intention is to call this method with different Classes and then cast it back to the previous type, but I get an error trying to cast it back afterwards.

Answer 1

You can try using Generics :

public List<T> Deserialize<T>(string path)
{
    IFormatter seri = new BinaryFormatter();

    Stream str = new FileStream(path, FileMode.Open, FileAccess.Read);
    List<T> Lista = (List<T>)(seri.Deserialize(str));
    str.Close();
    return Lista;
}

Answer 2

public List<T> Deserialize<T>(string path)
{
   return JsonConvert.DeserializeObject<List<T>>(path);
}
