剃刀中的选项选择对我不起作用

Question

此代码对我不起作用：

<div class="col-md-4">
  @Html.DropDownListFor(m => m.etattik, 
    new SelectList(new List<Object>
    { 
      new { value = 0 , text="text1"  },
      new { value = 1 , text = "text2" },
      new { value = 2 , text = "text3"}
    })
  )
  @Html.ValidationMessageFor(m => m.etattik)
</div>

它显示了{ value = 0 , text=text1 }

Answer 1

您没有为dataValueField指定dataTextField和SelectList：

@Html.DropDownListFor(
                        m => m.etattik, 
                        new SelectList(
                                  new List<Object>{ 
                                   new { value = 0 , text="text1"  },
                                new { value = 1 , text = "text2" },
                                  new { value = 2 , text = "text3"}
                                }
                    , "value", "text")
                        )
