使用structuremap当类型名中只有一个字符串时,如何解析类型

我没试过,但也许你可以用Type.GetType,比如。。。

var task = (ITask)ObjectFactory.GetInstance(Type.GetType("Assembly.Qualified.Name.Of.Type"));

这假设您知道类型的程序集/命名空间。

另一种可能性。。。

在扫描仪中添加

Scan(x =>
{
    x.AddAllTypesOf<ITask>();
}

private Dictionary<string, Type> typeLookup;
public ITask GetInstance(string typeName)
{
    if (typeLookup == null)
    {
        typeLookup = new Dictionary<string, Type>();
        var tasks = ObjectFactory.GetAllInstances<ITask>();
        foreach (var task in tasks)
        {
            typeLookup.Add(task.GetType().Name, task.GetType());
        }

    }
    return (ITask)ObjectFactory.GetInstance(typeLookup[typeName]);
}

你可以用 ObjectFactory.GetNamedInstance<IPerson>("Customer");

建议的方法是将其隐藏在工厂类后面:

public interface IPersonFactory
{
    IPerson GetPersonInstance(string name);
}

public class StructureMapPersonFactory : IPersonFactory
{
    public IPerson GetPersonInstance(string name)
    {
        return ObjectFactory.GetNamedInstance<IPerson>(name);
    }
}

public class SomethingThatNeedsNamedInstance
{
   IPersonFactory _factory;
   IPerson _personInstance;

   public SomethingThatNeedsNamedInstance(IPersonFactory factory)
   {
      this._factory = factory; // regular DI greedy constructor, setup in registry.
   }

   public void DoSomething()
   {
       this._personInstance = _factory.GetPersonInstance("Customer");
       _personInstance.CallSomeMethod();
   }
}
