Intellisense工作但我在尝试编译时遇到类型或命名空间错误

问题描述 投票：0回答：2

我正在编写一个.NET Web应用程序，我正在使用数据集来处理我的数据。

在代码中，一切看起来都很好（没有波浪形的红色下划线，实际上我可以选择我想要使用的tableadapter）。

但是，当我尝试运行该程序时，我收到此错误：

找不到类型或命名空间名称“ReleaseSet1TableAdapters”（您是否缺少using指令或程序集引用？

为什么代码工作但程序没有运行？附上代码图片，以显示我的绿色tableadapters，其中一切看起来都很好。

我的网格视图得到了同样的错误，这是在aspx文件中。感谢您的帮助;我不知所措。

代码摘录

enter image description here

这是aspx.cs文件：

using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Text;
using System.IO;
using System.Data.Sql;

public partial class Sched_Yesterday : System.Web.UI.Page
{
    ReleaseDataSet1TableAdapters.RollOutTableAdapter tblYesterday = new ReleaseDataSet1TableAdapters.RollOutTableAdapter();
    ReleaseDataSet1TableAdapters.RollOutTableAdapter tblYesterdaysDetail = new ReleaseDataSet1TableAdapters.RollOutTableAdapter();
    protected void Page_Load(object sender, EventArgs e)
    {
        gvYesterdaysReleases.DataSource = tblYesterday.GetDataByYesterdaySummary();
        gvYesterdaysReleases.DataBind();

        gvYesterdaysDetail.DataSource = tblYesterdaysDetail.GetDataByYesterday();
        gvYesterdaysDetail.DataBind();
    }
    public override void VerifyRenderingInServerForm(Control control)
    {
        //required to avoid the run time error "
        //Control 'GridView1' of type 'Grid View' must be placed inside a form tag with runat=server."
    }
}

和aspx文件：

我认为你需要改变前两行（在公共部分类行之后）看起来更像这样：

ReleaseDataSet1TableAdapters tblYesterday = new ReleaseDataSet1TableAdapters.RollOutTableAdapter();

注意第一部分已经改变了..你试图使用方法而不是类名来实例化一个类

基于此链接：Type or namespace could not be found from App_code folder我将构建操作更改为内容，现在所有内容都正确编译。我非常感谢大家的帮助，特别是@Syntax错误。
