Question

您好我是mvc的新手，我正在尝试将我的下拉值发送到数据库并将其发布到表格，任何建议最好的方式如何工作？ ..提前谢谢

ContactController.cs

public ActionResult Create()
{

    List<SelectListItem> items = new List<SelectListItem>();

     items.Add(new SelectListItem { Text = "English", Value = "0", Selected = true });

     items.Add(new SelectListItem { Text = "German", Value = "1" });

     items.Add(new SelectListItem { Text = "Spanish", Value = "2"});

     items.Add(new SelectListItem { Text = "Italian", Value = "3" });

     ViewBag.LanguageList = items;

    return View();
}

Create.cshtml

<div class="editor-label">
    @Html.LabelFor(model => model.language)
</div>
<div class="editor-field">
    @Html.DropDownListFor(model => model.language, new SelectList(ViewBag.LanguageList))
    @Html.ValidationMessageFor(model => model.language)
</div>

Index.cshtml

<td>
    @Html.DisplayFor(modelItem => item.language)
</td>

好的，请将您的Dropdown选项放在带有提交按钮的表单中：

using (Html.BeginForm("Create", "ContactController", FormMethod.Post, new { @class = "form-horizontal", role = "form" }))
      {
          @Html.AntiForgeryToken()
          <div class="editor-label">

          @Html.LabelFor(model => model.language)
          </div>
          <div class="editor-field">
          @Html.DropDownListFor(model => model.language, new SelectList(ViewBag.LanguageList))
          @Html.ValidationMessageFor(model => model.language)
          </div>
          <input type="submit" value="Enable" class="btn btn-link" />      
      }

控制器：

//This action can only be accessed with the Http.Post verb
[HttpPost]
//Validate the antiforgerytoken we set with `@Html.AntiForgeryToken()` in the view (Prevents CSRF attacks)
[ValidateAntiForgeryToken]
public ActionResult Create(YourModel model)
{

//Your model will now contain the value of the selected dropdown if you have wired up your model correctly.

//Connect to db, persist model.language

    return View();
}
