用户注册实现代码(Regist.aspx.cs)：
public partial class Regist : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void handon_Click(object sender, EventArgs e)
{
zhuce();
}
protected void zhuce()

Response.Write("<script>window.alert('添加用户"+UserName.Text+"成功！');</script>");
}
protected void Button1_Click(object sender, EventArgs e)
{
Response.Redirect("zxhIndex.aspx");
}
}
购物主界面的实现代码(shopping.aspx.cs)：
public partial class shopping : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
BindData();
string username = Session["username"].ToString();
Label1.Text = username;
bbsshow();
}
ConnectionStringSettings sets = ConfigurationManager.ConnectionStrings["DBConnection"];
SqlConnection conn;
protected void bbsshow()
{
conn = new SqlConnection(sets.ConnectionString);
SqlCommand cmd = new SqlCommand("select bbscontent from BBS ", conn);
conn.Open();
SqlDataReader reader = cmd.ExecuteReader();
