c# - 从 MVC3 Controller 中的多个选择列表中获取选定值

Question

有一个 View 显示 5 个下拉列表，其中填充了相关表中的所有可用类(class):

@model StudentRegistrationPortal.Models.CourseRegisterModel
@{
    ViewBag.Title = "registerCourses";
}

<h2>Welcome 
@Context.User.Identity.Name
</h2>
@Html.ActionLink("[Sign Out]", "SignOut", "Admin")

@using (Html.BeginForm())
{
@Html.ValidationSummary(true)
<fieldset>
    <legend>Following are available Courses - Please select Courses to  Register</legend>
    <table>
        <tr>
            <td>
                <div class="editor-label">
                    Course-1: 
                </div>
            </td>
            <td>
                <div class="editor-field">
                    @Html.DropDownListFor(m => m.Course.CId, Model.CoursesList)
                </div>
            </td>
        </tr>
        <tr>
            <td>
                <div class="editor-label">
                    Course-2: 
                </div>
            </td>
            <td>
                <div class="editor-field">
                    @Html.DropDownListFor(m => m.Course.CId, Model.CoursesList)
                </div>
            </td>
        </tr>
        <tr>
            <td>
                <div class="editor-label">
                    Course-3: 
                </div>
            </td>
            <td>
                <div class="editor-field">
                    @Html.DropDownListFor(m => m.Course.CId, Model.CoursesList)
                </div>
            </td>
        </tr>
        <tr>
            <td>
                <div class="editor-label">
                    Course-4: 
                </div>
            </td>
            <td>
                <div class="editor-field">
                    @Html.DropDownListFor(m => m.Course.CId, Model.CoursesList)
                </div>
            </td>
        </tr>
        <tr>
            <td>
                <div class="editor-label">
                    Course-5: 
                </div>
            </td>
            <td>
                <div class="editor-field">
                    @Html.DropDownListFor(m => m.Course.CId, Model.CoursesList)
                </div>
            </td>
        </tr>
    </table>


    <p>
        <input type="submit" value="Register" />
    </p>
</fieldset>
}
<div>
    @Html.ActionLink("Back to List", "Home","Student")
</div>

学生将从每个下拉列表中选择一门类(class)，然后按注册按钮。

我的问题是如何在相关 Controller 中获取所选类(class)？

谢谢。

你真正应该做的是在你的模型中拥有 SelectedCourse1、SelectedCourse2 等属性，相应地填充它们并将模型发送回 Controller
