c# - How to get object having constructor as other object in spring? -

i integrating .net application spring. have trouble getting object having constructor object.

my object patterns like:

  public class bar    {      private foo foo;          public void setfoo(foo foo)      {         this.foo = foo;      }      public string tostring()      {        return "bar! foo : \n" + foo;        }   }    public class foo   {      string id { get; set; }      string name { get; set; }   } 

my old c# code:

   foo foo1 = new foo();    foo1.id = 1;    foo1.name= "object 1, foo1";     foo foo2 = new foo();    foo2.id = 2;    foo2.name= "object 2, foo2";     bar b1 = new bar(foo1);    bar b2 = new bar(foo2); 

like without constructor using:

   bar bar = (bar)contextregistry.getcontext().getobject("bar"); 

i have searched on net , found need add foo in xml can't dynamic per call.

i know spring configuration , here is: in spring.config\

    <object id="bar" type="namespace.bar, projectname" singleton="false">        <constructor-arg ref="foo"/>     </object>      <object id="foo" type="namespace.foo, projectname" singleton="false">     </object>
