Question

Say we have:

class A
{
   ILogger myLog;
   A(ILogger log)
   {
      this.myLog = log;
   }
 ...
}

And we have registered the ILogger interface before in the unity container, e.g.

 container.RegisterType<ILogger, SomeLogger>();

And here the SomeLogger class:

class SomeLogger : ILogger
{
   string myString;
   SomeLogger(string test)
   {
     myString = test;
   }
 ...
}

Now, how can unity create an instance of SomeLogger for class A without passing a string to the ctor of SomeLogger?
Suppose there is no other ctor for SomeLogger. Where can one specify the parameter(s) for ctor of the mapped SomeLogger type?

Answer 1

you could also do this in the registration code as follows:

UnityContainer.RegisterType<ILogger, SomeLogger>();
UnityContainer.Configure<InjectedMembers>()
              .ConfigureInjectionFor<SomeLogger>(new InjectionConstructor("TestString"));
