列表框发布的表单数据

Question

im trying to post all the options' value in a select element(listBox) back to server to a MVC project

<select mulitple name="listboxA">
  <option value="one">text one</option>
  <option value="two">text one</option>
  <option value="three">text one</option>
</select>

However, on srever side, the value in Request.Form("listboxA") is "one,two,three," , there is an extra comma at the end, which result in an extra unwanted empty string in the parameter (type of List<string> ).

any ideas?

您可以在控制器上使用Request.Form["listboxA"].TrimEnd(',') 。
