Question

我是编程新手，请告诉我如何从MS Sql数据库中检索到的列值到标签。我从sql获得了如下数据

 SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["ShopsConnectionStringM"].ConnectionString);
 con.Open();
 sda = new SqlDataAdapter("Select UserName,Email,ShopCountry,PIN,ShopName,ShopCity,ShopDistrict,ShopState, Location,ShopBoard from Shops_Table where UserName= '" + HiddenField1.Value + "'", con);
 DataTable dt = new DataTable();
 sda.Fill(dt);

现在我有一个asp .net标签

<asp:Label ID="Label5" runat="server" Text="Label"></asp:Label>

我如何获得列的价值＆＃34;电子邮件＆＃34;到Label5？

可以这样做吗？

<asp:Label ID="Label5" runat="server" Text='<%#Eval("Email")%>'></asp:Label>

我不想使用后面的代码或c＃。

请帮忙。

有很多方法可以实现这一点。可以使用FormView：

标记

<asp:FormView ID="formView" runat="server">
    <ItemTemplate>
        <span><%# Eval("Email") %></span>
    </ItemTemplate>
</asp:FormView>

旁边的代码

SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["ShopsConnectionStringM"].ConnectionString);
con.Open();
sda = new SqlDataAdapter("Select UserName,Email,ShopCountry,PIN,ShopName,ShopCity,ShopDistrict,ShopState, Location,ShopBoard from Shops_Table where UserName= '" + HiddenField1.Value + "'", con);
DataTable dt = new DataTable();
sda.Fill(dt);
formView.DataSource = dt;
formView.DataBind();

另一种方法可能是使用Page DataBind，例如：

标记

<asp:Label ID="Label5" runat="server" Text='<%# Email %>'></asp:Label>

旁边的代码

SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["ShopsConnectionStringM"].ConnectionString);
    con.Open();
sda = new SqlDataAdapter("Select UserName,Email,ShopCountry,PIN,ShopName,ShopCity,ShopDistrict,ShopState, Location,ShopBoard from Shops_Table where UserName= '" + HiddenField1.Value + "'", con);
DataTable dt = new DataTable();
sda.Fill(dt);

Email = dt.Rows[0].Field<string>("Email);
DataBind(); //This is the Page data bind

您需要将电子邮件声明为属性。

protected string Email { get; set; }

如何在没有代码的情况下从sql获取列值到标签
