Reflection属性信息：如何在运行时仅显示一些属性 [英] Reflection Property Info :How to show only some Properties at runtime

问题描述

我的代码：

my code:

namespace Reflection
{
    class Program
    {
        static void Main(string[] args)
        {
            Type t = typeof(Product);
            PropertyInfo[] proInfo = t.GetProperties();
            foreach (var item in proInfo)
            {
                Console.WriteLine(item.Name);
            }
        }
    }
    public class Product
    {

        public int ProId { get; set; }
        public string ProName { get; set; }
        public string Description { get; set; }
        public decimal UnitPrice { get; set; }
    }
}

我得到所有属性名称作为输出。但我不想在输出中显示ProId和Decription。我怎么能这样做????

I get all properties names as output.But I dont want to show ProId and Decription in the output .How can i do that????

推荐答案

根据您的需要，另一种方法可能是使用BrowsableAttribute：

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

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; }
    }

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);
      }
   }

}

你不能追溯隐藏反映的公共财产 - 它无论如何都要检索它们。

当您定义访问修饰符以限制可用性时，您可以做的是更改访问修饰符：

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:

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

会隐藏属性。

Would hide the properties for you.
