Response.ClearContent() 方法未进入 Asp.net 核心

Question

        System.IO.StringWriter objStringWriter = new System.IO.StringWriter();
        System.Web.UI.HtmlTextWriter objHtmlTextWriter = new System.Web.UI.HtmlTextWriter(objStringWriter);
        gv.RenderControl(objHtmlTextWriter);



        Response.ClearContent();
        Response.Buffer = true;
        Response.AddHeader("content-disposition", "attachment; filename=DemoExcel.xls");
        Response.ContentType = "application/ms-excel";

        Response.Charset = "";
        Response.Output.Write(objStringWriter.ToString());
        Response.Flush();
        Response.Close();

给出错误响应不包含在 Asp.net Core 中 ClearContent 的定义

Response.Clear();
Response.Headers[HeaderNames.ContentDisposition] = "attachment; filename=DemoExcel.xls";
Response.WriteAsync(objStringWriter.ToString()).Wait()
