Consolidating input elements containing lamba expressions in ASP.NET MVC Razor View

I have an ASP.NET MVC view that contains a lot of similar code and I am trying to figure out if there is a way to consolidate it. Here is a sample for Question1, and I want to produce the same for 18 questions.

<div class="editor-label">
    @Html.LabelFor(model => model.Question1)
</div>
<div class="editor-field">
    @Html.EditorFor(model => model.Question1)
    @Html.ValidationMessageFor(model => model.Question1)
</div>

<div class="editor-label">
    @Html.LabelFor(model => model.Question1Type)
</div>
<div class="editor-field">
    @Html.EditorFor(model => model.Question1Type)
    @Html.ValidationMessageFor(model => model.Question1Type)
</div>

<div class="editor-label">
    @Html.LabelFor(model => model.Question1Required)
</div>
<div class="editor-field">
    @Html.EditorFor(model => model.Question1Required)
    @Html.ValidationMessageFor(model => model.Question1Required)
</div>

Is there a way to iterate through a loop for all the questions or some other mechanism in MVC to consolidate this code for 18 questions?

I think something like this will work:

@{
  var properties = new List<Func<Model, object>> 
                   { 
                       model => model.Question1, 
                       model => model.Question1Type, 
                       model => model.Question1Required
                   };
 }
 @foreach( property in properties ) {
     <div class="editor-label">
        @Html.LabelFor(property )
     </div>
     <div class="editor-field">
        @Html.EditorFor(property )
        @Html.ValidationMessageFor(property )
     </div>
 }

Take a look at this article. It explain how to bind a view from a list. With just some adjustment on your ViewModel it can be useful also for you, I believe.
