how to confige an abstract class with structure map

is there any problem with this kinda registration via structure map??

 static public class ContainerBootstrapper
{
    static public void BootstrapDefaultContainer(bool test = false)
    {
      StructureMap.ObjectFactory.Initialize(x =>
         {
           x.Scan(p =>
             {
                 p.AssemblyContainingType<IPropertyType>();
                 p.AddAllTypesOf<IPropertyType>();
                 //                     p.AddAllTypesOf<IPropertyType>().NameBy(c => c.Name);
             });

        });
  }





 public interface IPropertyType : IIdentityObject, IPriority
{
    string PropertyName { get; set; }

    ObjectType ObjectType { get; }

    string DisplayName { get; set; }

    IEntityType EntityType { get; set; }

    IList<IPropertyRuleObject> RuleObjects { get; set; }

    void AddRuleObject(IPropertyRuleObject ruleObject);

}



 public abstract class PropertyTypeBase : PersistentObject, IPropertyType
{
    public PropertyTypeBase()
    {

    }

    public PropertyTypeBase(string propertyName, string displayName)
    {
        PropertyName = propert开发者_如何学运维yName;
        DisplayName = displayName;
    }

   ....

 }



public class StringType : PropertyTypeBase
{
    private ObjectType _objectType;

    public StringType()
    {
        _objectType = new ObjectType(typeof(string));
    }

    public StringType(string propertyName, string displayName)
        : base()
    {
        PropertyName = propertyName;
        DisplayName = displayName;
    }

    public override ObjectType ObjectType
    {
        get { return _objectType; }
    }
}

when ContainerBootstrapper.BootstrapDefaultContainer(); execute I see this line of error:

StructureMap Exception Code:  200

Could not find an Instance named "StringType" for PluginType Azarakhsh.Domain.Core.AdaptiveObjectModel.Interface.IPropertyType

the calling code:

 public IPropertyType GetPropertyType(IIdentityObject identityObject, string name)
    {
        string[] Properties = name.Split('.');

        object Result = identityObject;

        foreach (var Property in Properties)
            Result = Result.GetType().GetProperty(Property).PropertyType.Name;

        IPropertyType propertyType = StructureMap.ObjectFactory.GetNamedInstance<IPropertyType>  (Result + "Type");
        if (propertyType==null)
            throw new Exception("Property type not found");

        return propertyType;
    }

what is the problem?

You are trying to get a named instance, but from what I can see of the code you have provided, you dont name your instances. The line of code that name your instances is commented out.

But even if you would just use the ObjectFactory.GetInstance<IPropertyType>(); here, you would have got an error because structuremap dont know what constructor to use. There are several solutions to theis problem.

1. Change your design so you only have one constructor
2. Mark your default constructor with the [DefaultConstructor] attribute, then it will work.

3. You can register it with objectFactory manually with something like this:

   x.For().Use().Ctor("propertyName").Is("someValue").Ctor("displayName").Is("someValue");

4. You can write a custom registrationconvention as described here
