Simple Application Example of ASP.NET Reflection

This article describes a simple application of asp.net reflection. Share it with everyone for reference, as follows:

Reflection provides objects that encapsulate assemblies, modules, and types (Type type). You can use reflection to dynamically create instances of types, bind types to existing objects, or obtain types from existing objects and call their methods or access their fields and properties. If properties are used in the code, reflection can be used to access them.----This is the simplest understanding of reflection. Below is a simple example to demonstrate the application of reflection technology!

One. Declare an interface that contains a virtual method. For example

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace ConsoleApplication1
{
  public interface IReflect
  {
    void Run(string name);
  }
}

Two. Implement the interface and implement the methods in the interface. For example

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace ConsoleApplication1
{
  public class Reflect : IReflect
  {
    public void Run(string name)
    {
      Console.WriteLine(name+"Start running!");
    }
  }
}

Three. Create instances of types using reflection technology and call methods of instances. For example

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Reflection;
namespace ConsoleApplication1
{
  class Program
  {
    static void Main(string[] args)
    {
      IReflect rec = (IReflect)Assembly.Load("ConsoleApplication1).CreateInstance("ConsoleApplication1.Reflect());
      rec.Run("aaa");
      Console.ReadLine();
    }
  }
}

This simple example is completed, and the displayed result is 'aaa started running'. The reflection naming control is System.Reflection. It is necessary to refer to this naming control when using it. The commonly used object of this naming control is Assembly, which contains many static methods. Load is a very typical one. CreateInstance is used to create an instance of an object.
