LINQ error invalid initializer member declarator

Question

I\'m a fairly junior C# developer so excuse me if this is trivial, but I am coming up with this error \"invalid initializer member declarator\" at the line of code I indicate be

You can't access complex object properties in a class initializer like that (as you are attempting with the PODetail.POHeaderId property). You might have to implement a small workaround: create a collection of anonymous objects with the information you have already, then reconstruct a concrete list of PODetailsListViewModels right afterwards:

var contactGrid = from l in poDetails.ToList()
                  select new {
                  {
                       Id = l.Id,
                       POHeaderId = l.POHeaderId
                       ...
                  };

And then you can manually recreate what you're looking for:

var someNewCollection = New List(Of PODetailsListViewModel);
foreach (var item in contactGrid)
    var model = new PODetailsListViewModel()
    {
         Id = item.Id
    };
    model.PODetail = new PODetailModel() /* replace with actual class name */
    {
        POHeaderId = item.POHeaderId
    };
    someNewCollection.Add(model);
}
return someNewCollection;

EDIT: Or perhaps you could nest the initializers:

var contactGrid = from l in poDetails.ToList()
                  select new PODetailsListViewModel() {
                  {
                       Id = l.Id,
                       PODetail = new PODetailModel()
                       {
                           POHeaderId = l.POHeaderId
                       },
                       ...
                  };
