Question

我正在创建一个asp.net mvc2项目。我想显示数据表中的数据但是当我运行项目时，它不会显示我想要显示的数据。

这些是我的代码：

HomeController.cs

    public ActionResult Index()
    {
        connection connect = new connection();
        string query = "SELECT Event_Name FROM tbl_Event WHERE Event_ID=2";

        return View(connect.SelectRecord(query));
    }

的Index.aspx

    <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<System.Data.DataTable>" %>

    <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
        Index
    </asp:Content>

    <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">

        <h2>Index</h2>
        <%Model.Rows[0].ItemArray[0].ToString(); %>

    </asp:Content>

connection.cs

        internal DataTable SelectRecord(string query)
        {
            try
            {
                OpenConnection();
                cmd = new SqlCommand(query, conn);
                adapter = new SqlDataAdapter(cmd);
                DataTable dt = new DataTable();
                adapter.Fill(dt);
                return dt;
            }
            catch (Exception ex)
            {
                throw ex;
            }
            finally
            {
                cmd = null;
                CloseConnection();
            }

        }

我想在Index.aspx中显示这一行＆lt;％Model.Rows [0] .ItemArray [0] .ToString（）; ％GT;

我在此链接中尝试了 Kurt Schindler 的答案： Displaying standard DataTables in MVC 但它没有指定如何显示数据表中的特定数据。请帮我。我使用datatable在asp.net视图上显示数据的原因是因为我很乐意将它用作我的临时数据存储。

试试这个

public ActionResult Index()
{
    connection connect = new connection();
    string query = "SELECT Event_Name FROM tbl_Event WHERE Event_ID=2";

    return View(connect.SelectRecord(query));
}
internal DataTable SelectRecord(string query)
{
        try
        {
            OpenConnection();
            cmd = new SqlCommand(query, conn);
            adapter = new SqlDataAdapter(cmd);
            DataTable dt = new DataTable();
            adapter.Fill(dt);
            return dt;
        }
        catch (Exception ex)
        {
            throw ex;
        }
        finally
        {
            cmd = null;
            CloseConnection();
        }

}

这是查看

查看:(强类型为System.Data.DataTable）

<table border="1">
<thead>
    <tr>
        <%foreach (System.Data.DataColumn col in Model.Columns) { %>
            <th><%=col.Event_Name%></th>
        <%} %>
    </tr>
</thead>
<tbody>
<% foreach(System.Data.DataRow row in Model.Rows) { %>
    <tr>
        <% foreach (var cell in row.ItemArray) {%>
            <td><%=cell.ToString() %></td>
        <%} %>
    </tr>
<%} %>         
</tbody>
