                    Response.ClearHeaders();
                    Response.ContentType = "application/pdf";
                    myReportDoc.ExportToHttpResponse(ExportFormatType.PortableDocFormat, Response, true, Session["ReportName"].ToString());

推荐答案

SAP 解释说:

该问题已被识别并记录在问题报告 ID ADAPT00765364 下.该错误可能是因为 Response.End() 在 ExportToHttpResponse() 方法中使用.
Reponse.End() 导致线程中止是一个已知问题.这是设计使然.
有关详细信息，请参阅 Microsoft KB312629 文章.

The issue has been identified and logged under Problem Report ID ADAPT00765364. The error is likely caused because Response.End() is used inside the ExportToHttpResponse() method.
It is a known issue that Reponse.End() causes the thread to abort. This is by design.
See Microsoft KB312629 Article for more info.

....
 try
   {
   reportDocument.ExportToHttpResponse(format, Response, true, Page.Title);
   }
 catch (System.Threading.ThreadAbortException)
   {
   }

 System.IO.Stream oStream = null;
 byte[] byteArray = null;
 oStream = boReportDocument.ExportToStream (ExportFormatType.PortableDocFormat);
 byteArray = new byte[oStream.Length];
 oStream.Read(byteArray, 0, Convert.ToInt32(oStream.Length - 1));
 Response.ClearContent();
 Response.ClearHeaders();
 Response.ContentType = "application/pdf";
 Response.BinaryWrite(byteArray);
 Response.Flush();
 Response.Close();
 boReportDocument.Close();
 boReportDocument.Dispose();

}
catch (Exception ex)
{
 string s = ex.Message;
}
