Depending on your needs another approach could be to use the BrowsableAttribute:

C#

public class Product
    {
        [Browsable(false)]
        public int ProId { get; set; }
        public string ProName { get; set; }
        public string Description { get; set; }
        [Browsable(false)]
        public decimal UnitPrice { get; set; }
    }

C#

Type t = typeof(Product);
PropertyInfo[] proInfo = t.GetProperties();
foreach (var pi in proInfo)
{
   object [] att = pi.GetCustomAttributes(typeof(BrowsableAttribute), false);
                
   if (att.Length > 0)
   {
      BrowsableAttribute b = att[0] as BrowsableAttribute;
      if (b.Browsable)
      {
         Console.WriteLine(item.Name);
      }
   }

}

You can't retrospectively hide public properties from reflection - it retrieves them regardless.
What you can do is change the access modifiers when you define them to restrict the availability:

C#

public class Product
    {
    protected int ProId { get; set; }
    public string ProName { get; set; }
    internal string Description { get; set; }
    public decimal UnitPrice { get; set; }
    }

Would hide the properties for you.
