Programatic property injection with Microsoft Unity


I use contructor injection in my solution, but this one class has a property that i do not want to pass in the constructor where i have the invariant dependencies.

Let's say i got an ILogger and it has a FileName property i want to set, while still having it set the dependancies in the contructor. How do i go about registering the type, and at the same time pass the defaunt connection string.

I hope there is an easy way to do it - preferably without decorating the property with an attribute, but if the setup is easier with the attribute i guess that's cool :)

So the question is, how do i inject a property value on an object that also uses contructor injection - with Unity.

UPDATE: I mentioned it in the title, but i forgot to elaborate in the body of the text - i want to set these dependencies up manually (in code) as opposed to in a config file.


Solution

  • Ok i guess it helped to ask the question, i found out - here it is.

    container.Configure<InjectedMembers>().ConfigureInjectionFor<BasicLogger>(
      new InjectionProperty("FileName", @"C:\test.log")
    );
