How to manage the state of the fields of an object through attributes?

Question

.NET

C# is used, the project is webforms, the task is to control the visibility of the web-control through attributes.
If it’s easier, you need to access the property of the object and change the property of this property :)
Here is a class with a field

public partial class Doc1 : BaseDoc{
        [Hide(1)]
        protected DateEdit tbe_DateTo;
}

There is an attribute

[AttributeUsage(AttributeTargets.Field)]
    public class HideAttribute: Attribute
    {
        public int State { get; set; }

        public HideAttribute(int state)
        {
            State = state;
        }
    }

I'm trying to change the property of a field

public abstract class BaseDoc{
        public void DoFieldManagement()
        {
            var managementsItems = GetType().GetMembers().Where(m => Attribute.IsDefined(m, typeof(HideAttribute))).ToList();

            foreach (var item in managementsItems)
            {
                WebControl control = new WebControl(HtmlTextWriterTag.A);
                if (item is FieldInfo)
                {
                    control = (WebControl)((FieldInfo)item).GetValue(typeof(WebControl));
                }
                var hideAttr = (HideAttribute)item.GetCustomAttributes(typeof(HideAttribute), true).First();

                if (hideAttr.State== 1)
                {
                    control.Visible = false;
                }
            }
}

For some reason, in this method, at the very beginning, an empty array gets into managementsItems.
Why is that?
Thank you)

Use BindingFlags :

var managementsItems = this.GetType().GetMembers
(
  BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.Public
).Where(m => Attribute.IsDefined(m, typeof(HideAttribute))).ToList();
