//使用Model

常规：

@{
    ViewBag.Title = "Index";
}

<h2>@(ViewBag.Mydata),123</h2>

循环遍历1：
@{
    ViewBag.Title = "Dic";
    var dic = ViewBag.dic;
    var str = ViewData["str"];
}

@{
   foreach(KeyValuePair<string,string> aa in dic)
  {
    <h1>@aa.Key : @aa.Value</h1>
  }
}
@{
    foreach (var bb in str as List<string>)
  {
    <h1>@bb</h1>
  }

}

循环遍历2：
@{
    Layout = "~/Views/Common/Layer.cshtml";
}

@using MvcApplication1.Models;

@model IEnumerable<Test>

@foreach (var item in Model)
{
    <p>@item.Sex</p>
}

数据集遍历


@using System.Data;
@using Lee;

@{
    ViewBag.Title = "Form";
    Layout = "~/Views/Common/Layer.cshtml";
    DataTable dt = (DataTable)ViewBag.Data;
}

@{

    <table class="table table-hover">
        <thead>
            <tr>
            @for (int i = 0; i < dt.Columns.Count;i++ )
            {
                <th>@dt.Columns[i].ToString()</th>
            }
           </tr>
        </thead>
        <tbody>
             @for (int j = 0; j < dt.Rows.Count;j++ )
            {
                <tr>
                    <td>@dt.Rows[j][dt.Columns[0].ToString()]</td>
                    <td>@dt.Rows[j][dt.Columns[1].ToString()]</td>
                    <td>@dt.Rows[j][dt.Columns[2].ToString()]</td>
                    <td>@dt.Rows[j][dt.Columns[3].ToString()]</td>
                </tr>
             }
