spring.net-Simple IOC Framework

Two classes:

public class Person
{
public string Name {get; set;}
public int Age {get; set;}

}

public class Persondao
{
private int Intpro;
Public Persondao (int intpro)
{
This.intpro = Intpro;
}
Public person Entity {get; set;}
public override string ToString ()
{
Return "constructor parameter Intpro" + Intpro;
}
}

<objects>
<object id= "Person" type= "springnet.person,springnet" >
<property name= "name" value= "Danche" ></property>

Test:

Objectfactory factory = objectfactory.intance (@ "f:\ cycle test \sringnetjykuangjia\springnet\objects.xml");
Persondao Persondao = Factory. GetObject ("Persondao") as Persondao;
Console.WriteLine (Persondao. Entity.name);
Console.WriteLine (Persondao. Entity.Age.ToString ());
Console.WriteLine (Persondao. ToString ());

Console.readkey ();
