在剃刀视图MVC中从数据库设置选定的下拉值

Question

I am explicitly creating a dropdownlist in razor mvc view. I would like the default option to be one of the items, the value of that item should come from database

View Code

<div class="form-group">
  @Html.LabelFor(model => model[i].Customer.HomeType, htmlAttributes: new { @class = "control-label col-md-2" })
    <div class="SerivcesRegistrationInput col-md-10">
      @Html.DropDownListFor(model => model[i].Customer.HomeType, new List<SelectListItem>
 {
     new SelectListItem{ Text="House", Value = "House",@(Model[i].CustomerServices.HomeType == "House" ? Selected = true : false)  },
     new SelectListItem{ Text="Apartment", Value = "Apartment" },
     new SelectListItem{ Text="Farm", Value = "Farm" } },
      "Select your home type", htmlAttributes: new { @class = "form-control" })
 }         
    </div>
</div>

Controller Code

 cs.HomeType = serviceDetails.HomeType;
 sp.CustomerServices = cs;
 return View("EditCustomerServices", ProviderList);

Model has the data I need but how can I set it to correct Dropdown list value. I tried using short hand if but it gives me an error

Invalid member initializer

Can I add if condition for Selected Boolean?

@{
    var selected = Model.CustomerServices.HomeType == "House";
}

<div class="form-group">
  @Html.LabelFor(model => model.Customer.HomeType, htmlAttributes: new { @class = "control-label col-md-2" })
    <div class="SerivcesRegistrationInput col-md-10">
      @Html.DropDownListFor(model => model.Customer.HomeType, new List<SelectListItem>
 {
     new SelectListItem{ Text="House", Value = "House", Selected = selected },
     new SelectListItem{ Text="Apartment", Value = "Apartment" },
     new SelectListItem{ Text="Farm", Value = "Farm" } },
      "Select your home type", htmlAttributes: new { @class = "form-control" })
 }         
    </div>
</div>
