Question

I have my own inherited App.Controller from Mvc.Controller which then all of my controllers inherit from. I wrote a provider utilizing an interface and implemented it as MyService and the constructor takes the Server property of Mvc.Controller which is of HttpServerUtilityBase.

However, I instantiate MyService in App.Controller‘s constructor. The problem is that the Server property of the Controller is null when constructing MyService. I have used public Controller () : base() { } to get the base to be constructed. However, Server remains null.

I would like to avoid Web.HttpContext.Current.Server if possible.

Has any one have a work around for this problem?

Edit: Well, I have implemented tvanfosson’s suggestion, and when my app constructs MyService in the property get method, Server is still null.

Edit 2: Nevermind, I was a goof. I had another Controller using Server aswell and did not change that. Case closed.

Use delayed initialization to construct your service.

private MyService service; public MyService Service {     get     {          if (this.service == null)          {              this.service = new MyService(this.Server);          }          return this.service;     } } 

Then, your service isn’t actually instantiated until it is used in the controller action and by that time the Server property has been set.
