SSRS 报表执行服务：导出到 xlsx 没有错误

Question

您好，感谢您的关注。

我有一些 .net 代码使用 SSRS 报告执行服务为用户下载报告作为 xlsx 文件。

它有效并且报告中的所有内容都存在并说明了。

虽然有一件烦人的事。当在 Excel 365 中打开时，它会弹出一个提示：

我们发现“theReport.xlsx”中的某些内容存在问题您是否希望我们尝试尽可能多地恢复？如果您信任此工作簿的来源，请单击是

当我单击“是”时，表明工作簿已修复并且报告看起来正常。

它没有在日志文件中给出任何修复的迹象，只是修复了它。

请看一下我的代码。也许有一些小的东西我可以改变以消除 Excel sheet 打开时的错误。

            string reportName = "reportName";
            string fileName = "filename";

            

            //create web services instance

            service.SetExecutionParameters(rptParams, "en-us");
            String SessionId = service.ExecutionHeaderValue.ExecutionID;
            byte[] result = service.Render(rptFormat, null, out extension, out encoding, out mimeType, out warnings, out streamIDs);

            Response.ClearContent();

          
                if (rptFormat == "EXCELOPENXML")
                {
               
                Response.AppendHeader("content-disposition", "attachment; filename=" + strRptFileName + ".xlsx");
                
                Response.ContentType = "application/application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
            }

            Response.BinaryWrite(result);
            Response.Flush();

        }

这终于奏效了。

private void executeReport(String reportName, ParameterValue[] rptParams, String rptFormat, string strRptFileName, ReportExecutionService service)
        {
            string encoding;
            string mimeType;
            string extension;
            Warning[] warnings = null;
            string[] streamIDs = null;
            string historyID = null;

            ExecutionInfo execInfo = new ExecutionInfo();
            ExecutionHeader execHeader = new ExecutionHeader();

            service.ExecutionHeaderValue = execHeader;
            execInfo = service.LoadReport(reportName, historyID);

            service.SetExecutionParameters(rptParams, "en-us");
            String SessionId = service.ExecutionHeaderValue.ExecutionID;
           
            byte[] result = service.Render(rptFormat, null, out extension, out encoding, out mimeType, out warnings, out streamIDs);

            Response.ClearContent();
            Response.Clear();
            
             
                if (rptFormat == "EXCELOPENXML")
                {
                 Response.AppendHeader("content-disposition", "attachment; filename=" + strRptFileName + ".xlsx");

                 Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
               
            }

            Response.BinaryWrite(result);
            Response.Flush();
            Response.SuppressContent = true;
            try
            { 
                HttpContext.Current.ApplicationInstance.CompleteRequest();
            }
            catch (ThreadAbortException ex)
            {
                //ignore
            }

        }
