Question

我有一个简单的ASPX页面，可以将动态生成的HTML表格呈现给Excel。它可以工作，但正如您从screenshot中看到的那样，由于某种原因打开工作簿会导致Excel实例没有GUI，除了公式栏和底部的工作表选项卡之外。它也不能轻易关闭或退出，似乎也会使我的工作站慢下来。

我正在使用此代码来构建和导出表。

        runReport2();//Builds the table - this bit is fine.

        Response.Clear();
        Response.Charset = "";
        Response.Cache.SetCacheability(HttpCacheability.NoCache);
        Response.ContentType = "application/vnd.ms-excel";
        Response.AddHeader("content-disposition", "attachment;filemename=" + "FleetReport.xls");

        System.IO.StringWriter sw = new System.IO.StringWriter(); 
        HtmlTextWriter hw = new HtmlTextWriter(sw);

        this.tblReport.RenderControl(hw);
        System.Text.StringBuilder sb1 = new System.Text.StringBuilder();

        sb1.Append(sw.ToString() );
        sw = null;
        hw = null;
        Response.Write(sb1.ToString());
        sb1.Remove(0, sb1.Length);
        Response.Flush();
        Response.End();

你能说出我可能做错了什么吗？我是以合理的方式做到这一点还是应该将CSV发送到Excel？

试试这种方式

        HttpContext.Current.Response.Clear();
        HttpContext.Current.Response.AddHeader("content-disposition", string.Format("attachment; Filename = FleetReport.xls"));
        Response.Charset = "";
        Response.Cache.SetCacheability(HttpCacheability.NoCache);
        HttpContext.Current.Response.ContentType = "application/ms-excel";
        StringWriter sw = new StringWriter();
        HtmlTextWriter hw = new HtmlTextWriter(sw);
        this.tblReport.RenderControl(hw);
        Response.Write(sw.ToString());
        Response.End();

GUI去了哪里？
