C # Methods for fetching (reading) property values from property names _c# Tutorial

Previously in the development of a program, I hope to be able to read the attribute value through the attribute name, but because it was not familiar with reflection, so did not find the right way to do a lot of repetitive work ah!

Then today I went online to find, was I found, to share with you.

In fact, the principle is not complex, that is, through reflection using attribute names to get property values, before the reflection unfamiliar, so did not think AH ~

It has to be said that reflection is a very powerful technique.

Here's the code, hoping to help people in need.

Using System;
Using System.Collections.Generic;
Using System.Linq;
Using System.Text;
Namespace Propertynamegetpropertyvaluedemo
{
 class program
 {
  static void Main (string[] args)
  { Person
   PS = new Person ();
   Ps. Name = "CTZ";
   Ps. Age =;
   Demo DM = new demo ();
   Dm. STR = "String";
   Dm. I = 1;
   Console.WriteLine (Ps. GetValue ("Name"));
   Console.WriteLine (Ps. GetValue ("Age"));
   Console.WriteLine (DM. GetValue ("Str"));
   Console.WriteLine (DM. GetValue ("I"));
  }
 Abstract class Abstractgetvalue
 {Public
  object GetValue (String propertyname) {return this
   . GetType (). 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 it's more complicated, look at the simplified version below.

Using System;
Using System.Collections.Generic;
Using System.Linq;
Using System.Text;
Namespace GetValue
{
 class program
 {
  static void Main (string[] args)
  {person
   PS = new Person ( );
   Ps. Name = "CTZ";
   Ps. Age =;

   Console.WriteLine (Ps. GetValue ("Name"));
   Console.WriteLine (Ps. GetValue ("Age"));
  }
 Class person
 {public
  string Name
  {get; set;}

  public int age
  {get; set;}
  public Object GetValue (String propertyname)
  {return this
   . GetType (). GetProperty (PropertyName). GetValue (this, null);}}

There is only one sentence of substance:

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

Others can be ignored.
