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

发布于 2020-12-05 09:39:31 
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;
        }
    }
}

I am trying to get private or protected properties~ but data.Length always return 0, sounds like it get nothing, why it?

Your class doesn't have any properties. These:

protected int i_Id;
protected string s_Name;

are fields. You can either change them to properties:

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

or you can use GetFields:

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

Mamba is a new state space model architecture showing promising performance on information-dense data such as language modeling, where previous subquadratic models fall short of Transformers. It is based on the line of progress on structured state space models, with an efficient hardware-aware design and implementation in the spirit of FlashAttention.
