C# Method to obtain (read) attribute value through attribute name

I was developing a program before, hoping to read out the attribute value through the attribute name, but because I was not familiar with reflection at that time, I did not find a suitable method and did a lot of repetitive work!

Then today I searched online again, and I found it, so I will share it with you.

In fact, the principle is not complicated. It is to use the attribute name to obtain the attribute value through reflection. I was not familiar with reflection before, so I didn't expect it~

I have to say that reflection is a very powerful technology. .

Here is the code, hoping to help those in need.

using System;
using ;
using ;
using ;
namespace PropertyNameGetPropertyValueDemo
{
 class Program
 {
  static void Main(string[] args)
  {
   Person ps = new Person();
    = "CTZ";
    = 21;
   Demo dm = new Demo();
    = "String";
    = 1;
   (("Name"));
   (("Age"));
   (("Str"));
   (("I"));
  }
 }
 abstract class AbstractGetValue
 {
  public object GetValue(string propertyName)
  {
   return ().GetProperty(propertyName).GetValue(this, null);
  }
 }
 class Person : AbstractGetValue 
 {
  public string Name
  { get; set; }

  public int Age
  { get; set; }
 }
 class Demo : AbstractGetValue
 {
  public string Str
  { get; set; }
  public int I
  { get; set; }
 }
}

If you think the above is more complicated, you can see the simplified version below.

using System;
using ;
using ;
using ;
namespace GetValue
{
 class Program
 {
  static void Main(string[] args)
  {
   Person ps = new Person();
    = "CTZ";
    = 21;

   (("Name"));
   (("Age"));
  }
 }
 class Person
 {
  public string Name
  { get; set; }

  public int Age
  { get; set; }
  public object GetValue(string propertyName)
  {
   return ().GetProperty(propertyName).GetValue(this, null);
  }
 }
}

There is only one substantive sentence:

().GetProperty(propertyName).GetValue(this, null);

Others can be ignored. .
