Asp.net mvc 3 .NET MVC 3提交按钮执行不同的操作

有人能给我解释一下为什么这样不行吗？我读过很多关于一个页面上有多个提交按钮的帖子，但我不明白后台发生了什么。我试着跟随别人在那些帖子里做的事情，但似乎都不管用。我只是想了解这里到底发生了什么。我怀疑这与页面发布时的具体情况有关

两个按钮的作用完全不同。第一个按钮发布表单。在表单的邮政编码中，它随后被重定向到车辆/索引。第二个按钮不会发布表单，而是直接转到/Vehicle/CreateNewVehiclePart

这是我想要的。我希望两个按钮都提交表单（这样我就可以在继续之前执行验证并保存对车辆的更改）。保存车辆数据后，我想根据单击的按钮移动到/Vehicle/AddPartsToVehicle或/Vehicle/CreateNewVehiclePart

<table class="layouttable">
    <tr>
        <td>
            @using (Html.BeginForm("AddPartsToVehicle", "Vehicle", FormMethod.Post, null))
            {
                <input type="submit" value="Add Parts To Vehicle" />
            }
        </td>
        <td>
            @using (Html.BeginForm("CreateNewVehiclePart", "Vehicle", FormMethod.Post, null))
            {
                <input type="submit" value="Create New Vehicle Part" />
            }
        </td>
    </tr>
</table>

@使用（Html.BeginForm（“AddPartsToVehicle”，“Vehicle”，FormMethod.Post，null））
{
}
@使用（Html.BeginForm（“CreateNewVehiclePart”，“Vehicle”，FormMethod.Post，null））
{
}
