Question

Is it possible to to something like this using Spring.NET IoC container?

MyClass instance = new MyClass();
ContextRegistry.GetContext().InjectDepenencies(instance);
// instance has the defined dependencies set

This would come in handy. Of couse I could use ContextRegistry.GetContext().Get("name") but that would create a new instance of the defined object. I would need to set the dependencies of an already created object.

Answer 1

There are three options available, the first one matches what you want.

IApplicationContext.ConfigureObject(object target, string name)

This configures the target object using the object definition which is matched by the name argument.
IApplicationContext.Get(string name, object[] arguments)

Which will either use the constructor or a static factory method which will receive the arguments as specified.
GenericApplicationContext.RegisterObjectDefinition(string name, IObjectDefinition definition)

You can use it to register dependencies at runtime.

Answer 2

ContextRegistry.GetContext().Get("name") will not create a new instance if name is defined as singleton which is the default scope in spring.net.
