ASP.. NET MVC: Razor <不匹配结束标签

我有一个充满列表模型的模型，我想使用foreach循环来显示它，但是....我的HTML看起来像这样:

<tr>
    <td class="lottery-unit lottery-unit-0"><img src="~/images/temp/1.png"></td>
    <td class="lottery-unit lottery-unit-1"><img src="~/images/temp/2.png"></td>
    <td class="lottery-unit lottery-unit-2"><img src="~/images/temp/4.png"></td>
    <td class="lottery-unit lottery-unit-3"><img src="~/images/temp/3.png"></td>
</tr>
<tr>
    <td class="lottery-unit lottery-unit-11"><img src="~/images/temp/7.png"></td>
    <td colspan="2" rowspan="2">
        <a href="#"></a>
    </td>
    <td class="lottery-unit lottery-unit-4"><img src="~/images/temp/5.png"></td>
</tr>
<tr>
    <td class="lottery-unit lottery-unit-10"><img src="~/images/temp/1.png"></td>
    <td class="lottery-unit lottery-unit-5"><img src="~/images/temp/6.png"></td>
</tr>
<tr>
    <td class="lottery-unit lottery-unit-9"><img src="~/images/temp/3.png"></td>
    <td class="lottery-unit lottery-unit-8"><img src="~/images/temp/6.png"></td>
    <td class="lottery-unit lottery-unit-7"><img src="~/images/temp/8.png"></td>
    <td class="lottery-unit lottery-unit-6"><img src="~/images/temp/7.png"></td>
</tr>

lottery-unit lottery-unit-0到lottery-unit lottery-unit-11是11我想要显示，tr是不固定的。如果我用razor这样写:

foreach (var item in Model)
{
    if (item.Order >= 0 && item.Order <= 3)
    {
        if (item.Order == 0)
        {
            <tr>                                                
        }
        <td class="lottery-unit lottery-unit-0"><img src="~/images/temp/1.png"></td>
        @if(item.Order == 3)
        {
            </tr>
        }
    }

以上将产生一些错误。那么如何编写正确的代码呢?

@foreach (var item in Model)
{
    if (item.Order >= 0 && item.Order <= 3)
    {
        if (item.Order == 0)
        {
            @:<tr>
        }
        <td class="lottery-unit lottery-unit-0"><img src="~/images/temp/1.png"></td>
        if (item.Order == 3)
        {
             @:</tr>
        }
    }
}
