ASP.NET MVC剃刀 - 如果里面 [英] ASP.NET MVC Razor - if inside for

问题描述

我试图用输出剃刀HTML表格。表本身的工作，但现在我想一个名为甚至类添加到其他每个表中的行：

 ＆LT;表＆gt;
    ＆LT;＆THEAD GT;
        ＆所述; TR＆GT;
            ＆所述;第i列1所述; /第i
            ＆所述;第i;柱2'/第i
            ＆所述;第i列第3版; /第i
        ＆LT; / TR＆GT;
    ＆LT; / THEAD＆GT;
    ＆LT;＆TBODY GT;
        @for（INT I = 0; I＆LT; ViewBag.MyList.Count;我++）
        {
            VAR myObject的= ViewBag.MyList [I]
            ＆LT; TR @if（我％2 == 0）{类=甚至}＆GT;
                ＆LT; TD＆GT; myObject.Column1＆LT; / TD＆GT;
                ＆LT; TD＆GT; myObject.Column2＆LT; / TD＆GT;
                ＆LT; TD＆GT; myObject.Column3＆LT; / TD＆GT;
            ＆LT; / TR＆GT;
        }
    ＆LT; / TBODY＆GT;
＆LT; /表＆gt;
 

有显然有点问题的循环中，如果情况，但什么是写这个正确的方法是什么？

解决方案

 ＆LT;表＆gt;
    ＆LT;＆THEAD GT;
        ＆所述; TR＆GT;
            ＆所述;第i列1所述; /第i
            ＆所述;第i;柱2'/第i
            ＆所述;第i列第3版; /第i
        ＆LT; / TR＆GT;
    ＆LT; / THEAD＆GT;
    ＆LT;＆TBODY GT;
        @for（INT I = 0; I＆LT; ViewBag.MyList.Count;我++）
        {
            VAR myObject的= ViewBag.MyList [I]
            ＆LT; TR @ {如果（我％2 == 0）{＆LT;文字和GT;类=甚至＆LT; /文字和GT; }}＆GT;
                ＆LT; TD＆GT; myObject.Column1＆LT; / TD＆GT;
                ＆LT; TD＆GT; myObject.Column2＆LT; / TD＆GT;
                ＆LT; TD＆GT; myObject.Column3＆LT; / TD＆GT;
            ＆LT; / TR＆GT;
        }
    ＆LT; / TBODY＆GT;
＆LT; /表＆gt;

I'm trying to output an HTML table using razor. The table itself works, but now I'm trying to add a class called "even" to every other row in the table:

<table>
    <thead>
        <tr>
            <th>Column 1</th>
            <th>Column 2</th>
            <th>Column 3</th>
        </tr>
    </thead>
    <tbody>
        @for (int i = 0; i < ViewBag.MyList.Count; i++)
        {
            var myObject = ViewBag.MyList[i];
            <tr @if (i % 2 == 0 ) { class="even" }>
                <td>myObject.Column1</td>
                <td>myObject.Column2</td>
                <td>myObject.Column3</td>
            </tr>
        }
    </tbody>
</table>

There's obviously something wrong with that if-case inside the loop, but what is the correct way of writing this?

解决方案

<table>
    <thead>
        <tr>
            <th>Column 1</th>
            <th>Column 2</th>
            <th>Column 3</th>
        </tr>
    </thead>
    <tbody>
        @for (int i = 0; i < ViewBag.MyList.Count; i++)
        {
            var myObject = ViewBag.MyList[i];
            <tr @{if (i % 2 == 0 ) { <text>class="even"</text> }}>
                <td>myObject.Column1</td>
                <td>myObject.Column2</td>
                <td>myObject.Column3</td>
            </tr>
        }
    </tbody>
</table>
