如何将静态元素添加到@ Html.DropDownListFor

Question

我使用此代码在我的视图中显示下拉菜单列表，我想在List的开头添加一个STATIC值，文本为None，值为“”。如何在剃刀中做到这一点？

  @Html.DropDownListFor(modal => modal.Candidates, new SelectList(Model.Candidates, "Value", "Key"))

Answer 1

DropDownListFor超载，default string，例如

 @Html.DropDownListFor(modal => modal.Candidates, 
                       new SelectList(Model.Candidates, "Value", "Key"), 
                       "None")
