【问题描述】：
我有一个控制器方法循环遍历我的“站点”数据库表，但目前它只发布数组中最后一项的内容，并且发布的次数与数据库中的站点相同。
这是我的看法
@foreach (Site s in sites)
{
<tr style="color:black">
@foreach (var col in Model.OffReportColumns)
{
<th>@col</th>
}
</tr>
foreach (var row in Model.OffReportRows)
{
<tr style="color:black">
@foreach (var cell in row)
{
<td>@cell</td>
}
</tr>
}
foreach (var row in Model.OffReporTotal)
{
<tr style="font-size: 20px">
@foreach (var cell in row)
{
<td>@cell</td>
}
</tr>
}
}
这是我的控制器

这是我的“站点”和“OffSiteItemDetails”表的一部分，用于显示结构
网站数据库
OffSiteItemDetails 数据库
我希望它循环并发布每个站点的值（它通过 (s.ID) 执行此操作。）它当前循环但它只是发布最后一个 s.Id（站点 ID）的数据表，它会这样做 5 次（有 5 个站点）。我希望它在每个站点循环时分开并发布数据，我只是不知道该怎么做
这是我的模型类
public class SummaryReportModel
{
public string Title { get; set; }
public string ReportTitle { get; set; }
public string OffReportTitle { get; set; }
public List<string> ValuationColumns { get; set; }
public List<string> OffReportColumns { get; set; }
public List<List<string>> ValuationRows { get; set; }
public List<List<string>> OffReportRows { get; set; }
public List<List<string>> Total { get; set; }
public List<List<string>> OffReporTotal { get; set; }
public List<List<string>> Tital { get; set; }
public List<List<string>> SecondTital { get; set; }
public List<List<string>> osiGrandTotal { get; set; }
}
【问题讨论】：
-
您是否进行了分析以确保您的“网站”数据在到达数据修饰方法之前是正确的？
-
@FrankThomas 是的，我有。这是正确的.. 我只是不知道如何为 5 个站点创建 5 个表，而不是为数组中的最后一个站点创建 5 个表
-
你能发布模型吗？我怀疑您将同一属性的值设置了五次。循环中的每次迭代都需要有自己的对象。例如，我希望在您的代码中看到带有 List
x...的 obj_A，您应该有 foreach(var item in myCollection){ var y = new property;//set values then...obj_a.x.添加（y）} -
“它当前循环，但它只发布最后一个 s.Id 的数据”不要为每个站点初始化
model.OffReportColumns和model.OffReportRows，而是使用model.OffReportRows.Add(...)。并删除视图中的foreach站点 -
@BillRuhl 这不是问题，我已经测试过了。我很确定问题是因为在循环完成之前我不会“返回模型”。到那时，这些值将等于数组中的最后一个值。我只是不确定如何在每个循环后返回它
