为什么获取私有属性什么也得不到? (C#)

Why does it get nothing that Getting private Properties? (c#)

public class A{
    public Info m_Info = new Info();
    Main()
    {
        Console.WriteLine(m_Info.Property_Count());
    }
    public class Info{

        protected int i_Id;
        protected string s_Name; 

        public int Property_Count(){
            System.Reflection.PropertyInfo[] data = this.GetType().GetProperties(BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.Instance | BindingFlags.Static);

            foreach(var item in data)
                Console.WriteLine(item.Name);
            return data.Length;
        }
    }
}

我正在尝试获取私有或受保护的属性~ 但是 data.Length 总是 return 0,听起来好像什么也得不到,为什么?

您的 class 没有 properties。这些:

protected int i_Id;
protected string s_Name; 

fields。您可以将它们更改为属性:

protected int i_Id { get; set; }
protected string s_Name { get; set; }

或者您可以使用 GetFields:

System.Reflection.FieldInfo[] data = this.GetType().GetFields(BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.Instance | BindingFlags.Static);
