2. Create a sample porject called DataAccess in C# console program

3. Add C:\Program Files\Spring.NET 1.3.2\bin\net\2.0\release\Spring.Core.dll  (2.0 means framework 2)

The solution file is like

The code is like below

Program.cs

   1: using System;
   2: using System.Collections.Generic;
   3: using System.Text;
   4: using Spring.Context;
   5: using Spring.Context.Support; 
   6: namespace DataAccess
   7: {
   8:   class MainApp
   9:   { 
  10:     static void Main()
  11:     {
  12:       DataAccessObject daoCategories = new Categories();
  13:       daoCategories.Run();
  14:  
  15:       DataAccessObject daoProducts = new Products();
  16:       daoProducts.Run();
  17:  
  18:       IApplicationContext context = ContextRegistry.GetContext(); 
  19:       DataAccessObject DAO = (DataAccessObject)context.GetObject("DataAccessObject");
  20:       DAO.Run();
  21:  
  22:       // Wait for user
  23:       Console.ReadKey();
  24:     }
  25:   }
  26:  
  27:   abstract class DataAccessObject
  28:   {
  29:     protected string connectionString; 
  30:  
  31:     public virtual void Connect()
  32:     {
  33:         Console.WriteLine("Connect '" + connectionString + "'"); 
  34:     }
  35:  
  36:     public abstract void Select();
  37:     public abstract void Process();
  38:  
  39:     public virtual void Disconnect()
  40:     {
  41:         Console.WriteLine("Discount\r\n");
  42:     }
  43:  
  44:     // The 'Template Method'
  45:     public void Run()
  46:     {
  47:       Connect();
  48:       Select();
  49:       Process();
  50:       Disconnect();
  51:     }
  52:   }
  53:   
  54:   class Categories : DataAccessObject
  55:   {
  56:     public override void Select()
  57:     {
  58:         Console.WriteLine("Get Categories"); 
  59:     }
  60:  
  61:     public override void Process()
  62:     {
  63:         Console.WriteLine("Process Categories"); 
  64:     }
  65:   }
  66:   
  67:   class Products : DataAccessObject
  68:   {
  69:     public override void Select()
  70:     {
  71:         Console.WriteLine("Get Products"); 
  72:     }
  73:  
  74:     public override void Process()
  75:     {
  76:         Console.WriteLine("Process Products"); 
  77:     }
  78:   }
  79: } 

App.config

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <sectionGroup name="spring">
      <section name="context" type="Spring.Context.Support.ContextHandler, Spring.Core"/>
    </sectionGroup>
  </configSections>
  <spring>
    <context>
      <resource uri="spring.xml.config"/>
    </context> 
  </spring>
</configuration>

 

 

spring.xml.config

<?xml version="1.0" encoding="utf-8" ?>
<objects xmlns="http://www.springframework.net">
  <object id="DataAccessObject" type="DataAccess.Products">
    <property name="connectionString" value="C:\db\northwind.mdb"/>
  </object>
</objects>

 

Running the application, the output is like

Spring.NET Installation and setup the first program_第3张图片

Now modify the spring.xml.config as below, only change “Products” to “Categories”

<?xml version="1.0" encoding="utf-8" ?>
<objects xmlns="http://www.springframework.net">
  <object id="DataAccessObject" type="DataAccess.Categories">
    <property name="connectionString" value="C:\db\northwind.mdb"/>
  </object>
</objects>

 

The output will be changed to

Spring.NET Installation and setup the first program_第4张图片

See the red highlight, it has changed the program direction without recompile the exe.
