图5.3管理员登陆页面
管理员登陆页面的部分代码为：
public partial class denglu : System.Web.UI.Page {
protected void Page_Load(object sender, EventArgs e) {
if (!this.IsPostBack) }
protected void ImageButton1_Click(object sender, ImageClickEventArgs e) {
SqlConnection con = DB.createDB(); SqlCommand cmd = new SqlCommand(); cmd.Connection = con; con.Open();
cmd.CommandText = \count(*) from tb_zhuce where name='\+ this.txtworkname.Text + \+ \
Session[\ Session[\
int a = Convert.ToInt32(cmd.ExecuteScalar()); // if (a > 0) {
Response.Redirect(\ } else {
Response.Write(\很遗憾，用户名或密码错误！');\ }
con.Close();
}
