导出到excel时线程被中止了吗？

我有一个绑定到GridView的DataTable.我还有一个按钮,单击时将DataTable导出到Excel文件.但是,发生以下错误:

ErrMsg ="线程正在中止."

以下是抛出错误的代码的一部分:

private static void Export_with_XSLT_Web(DataSet dsExport, 
                                         string[] sHeaders,
                                         string[] sFileds, 
                                         ExportFormat FormatType,
                                         string FileName)
{
    try
    {
        // Appending Headers
        HttpContext.Current.Response.Clear();
        HttpContext.Current.Response.Buffer = true;

        if(FormatType == ExportFormat.CSV)
        {
            HttpContext.Current.Response.ContentType = "text/csv";
            HttpContext.Current.Response.AppendHeader("content-disposition",
                                                      "attachment; 
                                                      filename=" + FileName);
        }
        else
        {
            HttpContext.Current.Response.ContentType = "application/vnd.ms-excel";
            HttpContext.Current.Response.AppendHeader("content-disposition", 
                                                      "attachment; 
                                                      filename=" + FileName);
        }

        // XSLT to use for transforming this dataset.                       
        MemoryStream stream = new MemoryStream();
        XmlTextWriter writer = new XmlTextWriter(stream, Encoding.UTF8);

        CreateStylesheet(writer, sHeaders, sFileds, FormatType);
        writer.Flush();
        stream.Seek(0, SeekOrigin.Begin);

        XmlDataDocument xmlDoc = new XmlDataDocument(dsExport);
        //dsExport.WriteXml("Data.xml");
        XslTransform xslTran = new XslTransform();
        xslTran.Load(new XmlTextReader(stream), null, null);

        using(StringWriter sw = new StringWriter())
        {
            xslTran.Transform(xmlDoc, null, sw, null);

            //Writeout the Content              
            HttpContext.Current.Response.Write(sw.ToString());                
            writer.Close();
            stream.Close();
            HttpContext.Current.Response.End();
        }
    }
    catch(ThreadAbortException Ex)
    {
        string ErrMsg = Ex.Message;
    }
    catch(Exception Ex)
    {
        throw Ex;
    }
    finally
    {

    }
}

改变HttpContext.Current.Response.End到HttpContext.Current.ApplicationInstance.CompleteRequest之后,它现在只是进入finally块,我无法弄清楚被抛出什么样的错误消息.

从以下行抛出ThreadAbortException:

HttpContext.Current.Response.End();

这里有更多细节和解决方法.

我试过用HttpContext.Current.ApplicationInstance.CompleteRequest.它确实有效,但也在下载文件的末尾导出了页面的完整HTML代码,这是不可取的.

Response.BuffferOutput = True;
Response.Flush();
Response.Close();

经过一番努力,我碰到了上面的代码.并且它在下载文件的末尾没有任何异常或不需要的代码,完美地工作.
