Question

我无法弄清楚如何获取登录表单。我在登录页面中有登录控制，我收到如下消息：

（当前上下文中不存在名称Login1）

using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data;
using System.Configuration;
using System.Data.SqlClient;
using System.Web.Security;

namespace User_Login
{
  public partial class Login : System.Web.UI.Page
  {
    protected void ValidateUser(object sender, EventArgs e)
    {
      int EMPLOYEE_ID = 0;
      string MyConnDB = ConfigurationManager.ConnectionStrings["MyConnDB"].ConnectionString;
      using (SqlConnection con = new SqlConnection(MyConnDB))
      {
        using (SqlCommand cmd = new SqlCommand("Validate_User"))
        {
          cmd.CommandType = CommandType.StoredProcedure;
          cmd.Parameters.AddWithValue("@USERNAME", Login1.UserName);
          cmd.Parameters.AddWithValue("@PASSWORD", Login1.Password);
          cmd.Connection = con;
          con.Open();
          EMPLOYEE_ID = Convert.ToInt32(cmd.ExecuteScalar());
          con.Close();
        }
        switch (EMPLOYEE_ID)
        {
          case -1:
            Login1.FailureText = "Username and/or password is incorrect.";
            break;
          case -2:
            Login1.FailureText = "Account has not been activated.";
            break;
          default:
            FormsAuthentication.RedirectFromLoginPage(Login1.UserName, Login1.RememberMeSet);
            break;
          }
        }
      }
    }
  }

确保您在Asp前端代码

中插入了以下控件

<asp:Login ID = "Login1" runat = "server" OnAuthenticate= "ValidateUser"></asp:Login>

名称Login在当前上下文中不存在
