How can StructureMap be used to create setter dependencies of objects that have primitive constructor argumeents?

I have an object "TestProperty" which implements "ITestProperty". "TestProperty" takes a string constructor argument. This is configured in StructureMap using something along the lines CtorDependency or WithCtorArg.

I want to inject the an instance of "ITestProperty" (implemented with "TestProperty") into another class as a property. When I try to run the code I get an exception (StructureMap Error Code 205, "Missing requested Instance property").

Here's a simplified version that recreates the problem:

Test:

[Test]
public void Can_resolve_the_correct_property()
{
    ObjectFactory.Initialize( x => x.AddRegistry( new TestRegistry() ) );

    var instance = ObjectFactory.GetInstance<TestController>();
}

Registry Setup:

public class TestRegistry : Registry
{
    public TestRegistry()
    {
        ForRequestedType<ITestProperty>().AddInstances( 
            i => i.OfConcreteType<TestProperty>().WithName( "Test" )
                .CtorDependency<string>( "arg" ).Is( "abc" )
        );

        //ForConcreteType<TestProperty>().Configure
            .CtorDependency<string>( "arg" ).Is( "abc" );

        ForConcreteType<TestController>().Configure
            .SetterDependency( p => p.Property ).Is<TestProperty>()
            .WithName( "Test" );
    }
}

Test Objects:

public interface ITestProperty { }

public class TestProperty : ITestProperty
{
    private readonly string arg;

    public TestProperty( string arg )
    {
        this.arg = arg;
    }

    public string Arg { get { return arg; } }
}

public class TestController
{
    public ITestProperty Property { get; set; }
}

When we go to initialize the "TestController" object above the exception is thrown. Is it possible to do this with StructureMap? Assuming that it is possible, what do I need to do to get it working?

Thanks in advance.

Solution

There are several ways to do this, as Josh mentioned if the named instance is important then you want this in your registry:

ForRequestedType<ITestProperty>().AddInstances(i => 
    i.OfConcreteType<TestProperty>().WithName("Test")
        .WithCtorArg("arg").EqualTo("abc"));

ForConcreteType<TestController>().Configure
    .SetterDependency(p => p.Property).Is(c => c
        .GetInstance<ITestProperty>("Test"));

Otherwise, you can do this:

ForRequestedType<ITestProperty>().TheDefault.Is
    .OfConcreteType<TestProperty>()
    .WithCtorArg("arg").EqualTo("abc");

ForConcreteType<TestController>().Configure
    .SetterDependency(p => p.Property).IsTheDefault();

Also, this is old StructureMap syntax, you might want to update to the latest version. Here is the new syntax:

For<ITestProperty>().Add<TestProperty>().Named("Test")
    .Ctor<string>("arg").Is("abc");

ForConcreteType<TestController>().Configure
    .Setter(p => p.Property).Is(c => c
        .GetInstance<ITestProperty>("Test"));
