Question

您好我想使用循环概念

生成这样的视图页面

No CType   PNum
1  Cap     12
2  Bottle  23

这是我的查看页面

 @for (int i = 1; i < (Enumerable.Count(@ViewBag.TestComponent_ComponentType)); i++)
            {
                foreach (string component_type in ViewBag.TestComponent_ComponentType)
                {
                    foreach (string part_number in ViewBag.TestComponent_ComponentPNumb)
                    {
                        <td>@i) </td>
                        <td> @Html.Raw(component_type)</td>
                        <td>(Part #:@Html.Raw(part_number))</td>
                        i = i + 1;
                    }
                }
            }

这是我的控制器

  ViewBag.TestComponent_ComponentType = context.Test_Component.Where(x => x.TestRequestId == id).Select(x => x.ComponentType).ToList();
  ViewBag.TestComponent_ComponentPNumb = context.Test_Component.Where(x => x.TestRequestId == id).Select(x => x.PartNumber).ToList();

请帮帮我。

首先，由于两个集合都具有来自同一对象属性的值，因此您不必构建两个集合。我建议你试试这个：在您的控制器中：

ViewBag.ComponentData = context.Test_Component.Where(x => x.TestRequestId == id).ToList();

在您看来：

@{
     List<Test_Component> compList = ViewBag.ComponentData;
     int count = 1;
 }
 <table>
 <tr>
      <th>No</th>
      <th>cType</th>
      <th>pNum</th> 
 </tr>
 @foreach(Test_Component t in compList)
 {
     <tr>
          <td>@count</td>
          <td>@t.ComponentType</td>
          <td>@t.PNum</td>
     </tr>
     count++;
 }
 </table>
