出口在Asp.Net中脱颖而出

Question

我的页面上有“导出到Excel”的按钮。 ButtonClick函数是将datgrid（dgrISGrid）导出到excel代码附加在下面： 但是当“线程被中止”执行其抛出错误时。解决方案是什么？

    protected void imgbtnExport_Click(object sender, ImageClickEventArgs e)
    {
      try
      {

        Response.Clear();
        Response.AddHeader("content-disposition", "attachment;filename=InformationSystems.xls");
        Response.Charset = "";
        Response.Cache.SetCacheability(HttpCacheability.NoCache);
        Response.ContentType = "application/vnd.xls";
        System.IO.StringWriter stringWrite = new System.IO.StringWriter();
        System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
        dgrISGrid.RenderControl(htmlWrite);
        Response.Write(stringWrite.ToString());
        Response.End();
      }
      catch (Exception ex)
      {

        ExceptionHandler ObjExceptionHandler = new ExceptionHandler();
        lblError.Text = ObjExceptionHandler.GetExceptionDetails(ex);
      }
    }

Answer 1

Response.End（）导致此错误。

尝试在此声明之前使用“Response.Flush（）”。
