how to bind value from database to dropdown list

@using System.Linq
@{    
   using(var uow = new UnitOfWork())
 {
     SelectList labelList = null;
     IEnumerable<label> labels = uow.Repository<label>().GetAll().ToList();

// Suppose you want to display name in DropDown

     var labelsList = labels.OrderBy(l => l.name).ToList();

// You can store current selected dropdown value in Session. Here is Session["labelId"].

     labelList = new SelectList(labelsList, "id", "name", (Session["labelId"] != null) ?   Convert.ToInt32(Session["labelId"]) : 0);

 }
}

// Now you can set labelList to the dropdown as itemsource.

<div>
 @Html.DropDownList("labelsDropDown", labelList as SelectList)
<div>
</div></div>
