  Lazy constructor injection using StructureMap 2.6.3

  Oct 06, 2011 10:17 AM|LINK

  Hello,

  I am very curious about how to perform lazy constructor injection using StructureMap 2.6.3.

  // Snippet 1
  public class AccountController : SpicyController, IAccountController
  {
      IVisitorAccountService visitorAccountService;
      IMemberAccountService memberAccountService;
  
      IVisitorAccountService visitor
      {
          get
          {
              if (visitor == null)
              {
                  visitorAccountService = ObjectFactory.GetInstance<IVisitorAccountService>();
              }
  
              return visitorAccountService;
          }
      }
      
      IMemberAccountService member
      {
          get
          {
              if (visitor == null)
              {
                  memberAccountService = ObjectFactory.GetInstance<IMemberAccountService>();
              }
  
              return memberAccountService;
          }
      }
      
      // etc...
  }
  
  
  
  // Snippet 2
  public class AccountController : SpicyController, IAccountController
  {
      readonly IVisitorAccountService visitor;
      readonly IMemberAccountService member;
  
      public AccountController(IVisitorAccountService visitorAccountService, IMemberAccountService memberAccountService)
      {
          this.visitor = visitorAccountService;
          this.member  = memberAccountService;
      }
      
      // etc...
  }

  I want to be able to do something like Snippet 1 but using constructor injection (like in Snippet 2).

  Note: I use C# 4.
