c# - 登录用户名和文本框文本未保存在数据库中

Question

我有一个登录控件，在其中添加了一个额外的文本框，我想在登录时将日期时间，用户名和文本框数据保存到数据库中（登录没有任何问题）。日期时间正在保存，但用户名和文本框文本未保存。以下是我的aspx.cs代码：-

 protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                TextBox Txt = (TextBox)Login1.FindControl("TextBox1"); //Login1 is loginID and TextBox1 is textbox ID
                if (Txt != null)
                {
                    Txt.Focus();
                }
            if ((Session["Check"] != null) && (Convert.ToBoolean(Session["Check"]) == true))
            {
                    // If User is Authenticated then 
                    if (User.Identity.IsAuthenticated)
                    //call the method to execute insert to the database
                    ExecuteInsert(Txt.Text,
                               DateTime.Now,
                               Login1.UserName); //Login1 is login ID
                }
            }

            if (!this.IsPostBack)
                ViewState["LoginErrors"] = 0;
        }     

插入方法：

     private void ExecuteInsert(string AuditorComments, DateTime AuditDate, string Auditor)
            {
                SqlConnection conn = new SqlConnection("Data Source = usftdl0008; Initial Catalog = *******;Persist Security Info=True;User ID=*****;Password=*****; Integrated Security = TRUE");
                string sql = "UPDATE TBLhsCaser SET AuditorComments = @AuditorComments, AuditDate = @AuditDate, Auditor = @Auditor WHERE AuditDate IS NULL ";

                try
                {
                    conn.Open();
                    SqlCommand cmd = new SqlCommand(sql, conn);
                    SqlParameter[] param = new SqlParameter[3];
                    //param[0] = new SqlParameter("@id", SqlDbType.Int, 20);
                    param[0] = new SqlParameter("@AuditorComments", SqlDbType.VarChar, 50);
                    param[1] = new SqlParameter("@AuditDate", SqlDbType.DateTime, 50);
                    param[2] = new SqlParameter("@Auditor", SqlDbType.VarChar, 50);

                    param[0].Value = AuditorComments;
                    param[1].Value = AuditDate;
                    param[2].Value = Auditor;


                    for (int i = 0; i < param.Length; i++)
                    {
                        cmd.Parameters.Add(param[i]);
                    }

                    cmd.CommandType = CommandType.Text;
                    cmd.ExecuteNonQuery();
                }
                catch (System.Data.SqlClient.SqlException ex)
                {
                    string msg = "Insert Error:";
                    msg += ex.Message;
                    throw new Exception(msg);
                }
                finally
                {
                    conn.Close();
                }

            }

Answer 1

使用以下代码检索登录用户的用户名：

MembershipUser u;
string uname;

u = Membership.GetUser();
uname = u.UserName;

请注意，我通常不使用C＃编写代码，因此您可能需要稍微调整上面的代码。



关于textbox1控件，您是否检查了呈现的页面以查看textbox1是否仍然是控件的ID？毕竟，ASP会动态呈现这些ID。尝试将此作为属性添加到控件，并查看当前代码是否有效：

ClientIDMode="Static"
