我希望我的HTML表显示空白行，以使每次的总行数相同，以便该表可以始终填充屏幕。我正在处理一个对象列表，我想遍历显示在一行上的每个对象，然后再遍历几次，直到达到固定的迭代次数。
我目前有一个剃须刀foreach循环，该循环遍历每个对象并将它们显示为行。我的主意是使用像这样的for循环来做
for (int i=0; i<10; i++)
{ row for object }
如何访问每个对象以在for循环中显示它？
编辑：这是更多代码
@foreach (var exampleObject in Model)
{
if (exampleObject.Position == "examplePosition")
{
<tr>
<td>@exampleObject.Name<span class="rotate">
<text class="button">@Html.ActionLink(HttpUtility.HtmlDecode("✎"), "Edit", new { id = exampleObject.ID }, new { style = "color:Black" })</text></span>
</td>
<td>@exampleObject.Rooms</td>
<td>@exampleObject.Phone</td>
<td><text class="button" style="float:right">@Html.ActionLink(HttpUtility.HtmlDecode("☒"), "Delete", new { id = exampleObject.ID }, new { style = "color:Black" })</text>@exampleObject.Location</td>
</tr>
}
}
最终编辑：我找到了一种草率的方法，但这很简单，也是我找到的唯一方法。在上面的代码之后，我做到了：
@for (var i = 0; i < 1; i++)
{
var s = 0;
foreach (var exampleObject in Model)
{
if (exampleObject.Position == "examplePosition")
{
s++;
}
}
for (i = s; i < 12; i++)
{
<tr>
<td colspan="4">
</td>
</tr>
}
}
我基本上制作了一个for循环，该循环重复一次，以便可以在表内部使用一些嵌套剃刀（我知道这是不好的作法）。然后，我计算了通过foreach循环在此特定位置的表上显示的数量，并将数量设置为在草率的for循环中声明的局部变量。然后，我进行了另一个for循环，这次将i设置为我已经拥有的行数，并将其设置为迭代并显示一个空行，只要该行数低于我的首选数即可。这是一种草率的方法，但嘿，它有效。
最终决赛编辑：
我整理了一下，看来效果更好。
@{
var counter = 0;
foreach (var exampleObject in Model)
{
if (exampleObject.Position == "examplePosition" && counter < 13)
{
<tr>
<td>@exampleObject.Name</td>
<td>@exampleObject.Rooms</td>
<td>@exampleObject.Phone</td>
<td>@exampleObject.Location</td>
</tr>
counter++;
}
}
for (int i=counter; i<13; i++)
{
<tr><td colspan="4"> </td></tr>
}
}

您可以实现分页。这是一种检索请求数据页的简单方法。

这是一个例子
var tableRowCount = 100;
@for(var i = 0; i < tableRowCount; i++)
{
if (i < Model.Count )
{
<tr>
<td>@exampleObject.Name<span class="rotate"><text class="button">@Html.ActionLink(HttpUtility.HtmlDecode("✎"), "Edit", new { id = exampleObject.ID }, new { style = "color:Black" })</text></span></td>
<td>@exampleObject.Rooms</td>
<td>@exampleObject.Phone</td>
<td><text class="button" style="float:right">@Html.ActionLink(HttpUtility.HtmlDecode("☒"), "Delete", new { id = exampleObject.ID }, new { style = "color:Black" })</text>@exampleObject.Location</td>
</tr>
}
else
{
<tr>
<td colspan="3" > </td>
</tr>
}
}
