c# - 无法访问我的对象的成员

Question

Error : 'object' does not contain a definition for 'lp' and no extension method >'lp' accepting a first argument of type 'object' could be found (are you missing >a using directive or an assembly reference?

如果我尝试从我的对象中获取一个值，我会得到这个...

但是当我在不尝试获取值的情况下运行时，我可以清楚地看到我的对象确实包含 lp...

反序列化的完整代码...

public object Deserialize(Object obj, string path)

        {

            XmlSerializer serializer = new XmlSerializer(obj.GetType());

            StreamReader reader = new StreamReader(path);
            obj = serializer.Deserialize(reader);
            reader.Close();
            return obj;

        }

人类...

public class Person
    {
        public string name { get; set; }
        public int age { get; set; }

    }

PersonList 类...

public class PersonList

    {
        public List<Person> lp = new List<Person>();


        public void AddPerson(Person p)
        {
            lp.Add(p);
        }
    }

这是我发送给公共(public)类 PersonList 的 Person List 的一个实例

{
    public List<Person> lp = new List<Person>();


    public void AddPerson(Person p)
    {
        lp.Add(p);
    }
}.

UPDATE: I was doing casting before but I will be passing in loads of different types of objects so wanted a generic Deserialize function. is there a way to do this? –

您更新了您的问题，要求进行通用转换，而泛型正是您要找的。

public T Deserialize<T>(T obj, string path)
{
    XmlSerializer serializer = new XmlSerializer(typeof(T));

    StreamReader reader = new StreamReader(path);
    obj = (T)serializer.Deserialize(reader);
    reader.Close();
    return obj;
}
