   <tbody>
   <tr>
   <td align="left" >
   <select id="formsSelect" style="font-family: arial,sans-serif;font-size:10px;>      
  <%
  for (int x = 0; x < forms.Count; x++)
  {
  %>
      <option><%= forms[x].ToString() %></option>        
 <%
  }
 %>
</select>

<input  type="submit" name="formType" value="Search" style="color: #000000;"/> 
</td>
</tr>
</tbody>
</table>
</form>

Answer 1

使用JavaScript，您可以将其作为

<script type="text/javascript">
   var ddl = document.getElementByID('formsSelect');
   // The value is persent in ddl, you can use it as
   var selectedvalue= ddl.options[ddl.selectedIndex].value; 
</script>

你不能在代码背后获得html控件值，你应该使用asp：DropDownList控件，然后你就会得到

    protected void Dropdown_SelectedIndexChanged(object sender, EventArgs e)
    {            
     string val= Dropdown.SelectedValue.tostring();
    }

Asp.net：从.cs文件中的下拉列表中获取所选值
