Question

我有一个从存储过程中读取的List。它只是一个选择声明。我不知道为什么我收到错误“在所选数据源中找不到字段或属性名称'Ticket ID'。”我正在做的是用我的代码用预定义的列填充gridview。

  public List<SelectQueuedTickets> GetQueuedTickets()
    {
        List<SelectQueuedTickets> QueuedTicketsList = new List<SelectQueuedTickets>();

        using (SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString))
        {

            using (SqlCommand com = new SqlCommand("[Reader].[usp_SelectQueuedTickets]", con))
            {
                con.Open();
                com.CommandType = CommandType.StoredProcedure;
                SqlDataReader rd = com.ExecuteReader();

               while (rd.Read())
                {
                    this.TicketID = Convert.ToString(rd["Ticket ID"]);
                    this.PriorityID = Convert.ToInt32(rd["Priority"]);
                    this.FormType = Convert.ToString(rd["Form Type"]);
                    this.Summary = Convert.ToString(rd["Summary"]);
                    this.CreationDate = Convert.ToDateTime(rd["Creation Date"]);
                    this.OwnerGroup = Convert.ToString(rd["Owner Group"]);
                    this.Owner = Convert.ToString(rd["Owner"]);
                    this.Creator = Convert.ToInt32(rd["Creator"]);
                    this.AffectedUser = Convert.ToInt32(rd["Affected User"]);
                    this.OwnerEmail = Convert.ToString(rd["Owner Email"]);
                    this.AffectedUserEmail = Convert.ToString(rd["Affected User Email"]);

                    QueuedTicketsList.Add(this);
                }
            }
        }
        return QueuedTicketsList;

    }


   protected void LoadQueuedTickets()
    {
        SelectQueuedTickets selectqueuedtickets = new SelectQueuedTickets();
        GridView1.DataSource = selectqueuedtickets.GetQueuedTickets();
        GridView1.DataBind();
    }

您返回和期望从存储过程返回的内容之间似乎存在不匹配。我会逐字段比较，看看没有丢失或拼写错误的列名。在Management studio中运行proc并将其与您在代码中引用的字段进行比较

在所选数据源中找不到字段或属性名称
