是否可以使用 ServerReport.Render 或 ServerReport.RenderStream 将报告导出到 SSRS 2008 R2 上的 CSV 可编程性？

这很奇怪，因为我们可以使用 Report Viewer 来做到这一点，但是当使用渲染在代码中将格式更改为 CSV 时，我会遇到一些异常。

这是我正在使用的代码，可以完美地以 XLS、DOC 和 PDF 格式导出报告：

        private void ExportReport(String format)
    {
        // Variables
        Warning[] warnings;
        string[] streamIds;
        string mimeType = string.Empty;
        string encoding = string.Empty;
        string extension = string.Empty;

        string fileName = _reportName.Replace("Rep", "Report") + "_" + DateTime.Now.ToString("yyyyMMdd HH:mm");

        PrepareReportParameters();
        rv.ServerReport.SetParameters(lstReportParameters);

        byte[] bytes = rv.ServerReport.Render(format, null, out mimeType, out encoding, out extension, out streamIds, out warnings);

        // Now that you have all the bytes representing the PDF report, buffer it and send it to the client.
        Response.Buffer = true;
        Response.Clear();
        Response.ContentType = mimeType;
        Response.AddHeader("content-disposition", "attachment; filename=" + fileName + "." + extension);
        Response.BinaryWrite(bytes); // create the file
        Response.Flush(); // send it to the client to download
    }

这是我在上述方法中选择“CSV”作为“字符串格式”时遇到的异常：

You have attempted to use a rendering extension that is either not registered for this report server or it is not supported in this edition of Reporting Services. (rsRenderingExtensionNotFound)

谢谢
