dependency injection

This article is about the DI of spring.net.

The underlying statement demonstrates how the spring.net works.

First:Config your file App.config as follows.

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <configSections>
        <sectionGroup name="spring">
            <section name="context" type="Spring.Context.Support.ContextHandler, Spring.Core"/>
            <section name="objects" type="Spring.Context.Support.DefaultSectionHandler, Spring.Core" />
        </sectionGroup>
    </configSections> 
    <spring>
        <context>
            <resource uri="config://spring/objects"/>
        </context>
        <objects> 
          <object name="MyDataAccess" type="DataAccessComponent.DefaultDataAccess,DataAccessComponent" />                 
          <object name="jialefuDataAccess" type="DataAccessComponent.jialefu,DataAccessComponent" /> 
        </objects>
    </spring> 
</configuration>

Please pay attention on the node of <object />.It contains the information of name,class,assembly.It is the reason why you

can activate specific instance(that is [assembly]class) according to the name.

Second.

You can create your arbitrary instance in your program.

 IApplicationContext context = ConfigurationManager.GetSection("spring/context") as IApplicationContext;
          
            IDataAccess dac = context.GetObject("MyDataAccess") as IDataAccess;
            var r1 = dac.ExecuteNonQuery("");
             
            IDataAccess da = context.GetObject("jialefuDataAccess") as IDataAccess;
           var r=  da.ExecuteNonQuery("");
