Answer 1

如果你想从DB读取，你必须做这样的事情。

SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["TestConString"].ConnectionString);
    con.Open();
    SqlCommand cmd = new SqlCommand("SELECT User_Type FROM [User] WHERE User_Id =@userid and User_Password=@password", con);
    cmd.Parameters.AddWithValue("@userid", Convert.ToInt32(txtUserName.Text));
    cmd.Parameters.AddWithValue("@password", txtPassword.Text);
    var reader = cmd.ExecuteReader();
    if (reader.HasRows)
    {
    reader.Read();
    string userType = reader.GetString(0);
        Session["USER_ID"] = txtUserName.Text;
        Response.Redirect("Dashboard.aspx");
    }
    else
    {
        Response.Write("Login Failed");
    }

下面是使用从数据库返回的User_Type的示例：

    if (dt.Rows.Count > 0)
    {

        Session["USER_ID"] = txtUserName.Text;

        switch((string)dt.Rows[0]["User_Type"])
        { 
            case "UserType1":
                Response.Redirect("UserType1Dashboard.aspx");
                break;
            case "UserType1":
                Response.Redirect("UserType2Dashboard.aspx");
                break;
            case "UserType1":
                Response.Redirect("UserType3Dashboard.aspx");
                break;
            default:
                Response.Redirect("Dashboard.aspx");
                break;
        }
    }
    else
    {
        Response.Write("Login Failed");
    }
