Can't figure out razor syntax for my strongly typed view

I have a strongly typed view where I am trying to display a model when an id is passed to my Controller action method.

I am trying to construct a link to each of this models as well.

For the purpose before the beginning of my foreach I have an i=0, and then I am trying to increase it by 1 using i++. The problem is that the the i++ part doesn't work -- I have always zero as an id in my link. Why?

Can someone help with this?

@{
    var i = 0;
    foreach (var item in Model)
    {
    <tr>
        <td>
            @Html.DisplayFor(modelItem => item.Title)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.Content)
        </td>
        <td>

            @Html.ActionLink("Details", "Details", new { id = i }) 
           i++;
        </td>
    </tr>
        }
    }

Razor does its best to distinguish code from markup/html/text, which isn't easy in general. And in this case, i++ is considered text.

The reason is that there are tags following the foreach { part, causing the reading mode to switch to markup/html/text. In that mode only @..., @{... or } are recognized as code, and everything else is treated as markup/html/text.

If this happens, just put @{ ... } around your statements, like this:

<td>
    @Html.ActionLink("Details", "Details", new { id = i }) 
    @{
        i++;
    }
</td>
