Can't use foreach as Model does not contain a definition for GetEnumerator ()…but I think it does!

View, Web Forms,

I’m passing this collection to my view:

List <UserGoalsStepViewModel> userGoals = new List<UserGoalsStepViewModel>();
//I populate this List with ViewModel objects and then pass it to the view...

foreach (UseCase uc in useCases)
{
userGoals.Add (new UserGoalsStepViewModel {
GoalTitle = uc.Title,
ActorTitle = uc.actor.Title,

});

}
return View(userGoals);

Then, in my declaration in my View I have this:

@model IEnumerable<JustSpecIt.ViewModels.UserGoalsStepViewModel>

However, when I use a `@foreach` in my View, I get the dreaded red squiggle telling me I can’t use foreach because the variable type doesn’t contain a definition for GetEnumerator() – I thought the model declaration in the View would have taken care of that?

What should I change?

Help much appreciated!

What should I change?

gazrolo4

return View(userGoals);
return View(userGoals.AsEnumerable());

Thanks for the response but I added that and it didn’t make a difference I’m afraid. Would I be better using some other type of collection in the first place, rather than a list? 

gazrolo4

@model IEnumerable<JustSpecIt.ViewModels.UserGoalsStepViewModel>
@model List<JustSpecIt.ViewModels.UserGoalsStepViewModel>

That stops my view recognising any of my model properties 

show your view and action code

Hi gazrolo4,

There is the GetEnumerator method in IEnumerable interface.

# IEnumerable.GetEnumerator Method

http://msdn.microsoft.com/en-us/library/system.collections.ienumerable.getenumerator(v=vs.110).aspx

Please check your code. The code could be like this:

@foreach(UserGoalsStepViewModel item in Model)
{
  <div>item.Title</div>
}

Best Regards
