在aspx页面中显示DataTable信息

Question

我是 Asp.net 新手。我创建了一个登录页面，用于检索数据表中的用户信息。我将此信息存储在会话变量中。

这是代码：

 using System;
using System.Data;
using System.Data.SqlClient;
using System.Configuration;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using System.Data;
using System.Web.Configuration; 


public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{

}
protected void btnSubmit_Click(object sender, EventArgs e)
{
    SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["dbconnection"].ConnectionString);
    con.Open();
    SqlCommand cmd = new SqlCommand("select * from UserTable where UserName =@username and Password=@password", con);
    cmd.Parameters.AddWithValue("@username", txtUserName.Text);
    cmd.Parameters.AddWithValue("@password", txtPWD.Text);
    SqlDataAdapter da = new SqlDataAdapter(cmd);
    DataTable dt = new DataTable();
    da.Fill(dt);
    if (dt.Rows.Count > 0)
    {
        Session["userdata"] = dt;
        Response.Redirect("Home.aspx");
    }
    else
    {
        ClientScript.RegisterStartupScript(Page.GetType(), "validation", "<script language='javascript'>alert('Invalid Username and Password')</script>");
    }
}
}

现在想要显示Home.aspx中的DataTable信息。我怎样才能做到这一点？

Answer 1

使用网格视图..

<asp:GridView ID="GridView1" runat="server">
</asp:GridView>

在运行时它仅呈现为表格..

然后

GridView1.DataSource=Session[userdata];
GridView1.DataBind();
