                    if (ViewState["WithTaxesId"].ToString() == "Y")
                    {
                        if (ViewState["ShowTaxesId"].ToString() == "I")
                        {
                            CrystalReportSource1.Report.FileName = Server.MapPath("~/Crystal Report Files/quotation_withtax-I.rpt");

                            string reportpath = Server.MapPath("~/Crystal Report Files/quotation_withtax-I.rpt");

推荐答案

您使用的是哪个版本?
很难说你在做什么错.但是这里有一些网站和文章可能会帮助您发现问题，并且可能是您目前正在执行的操作的替代方法(您不应该使用ExportToHttpResponse吗?).
我假设oRpt是 ReportDocument对象 [ ^ ]?
MSDN在 ReportDocument.Export方法上有一个链接[ ^ ]从版本10开始可用.
似乎 ReportDocument.ExportToDisk [ ExportToHttpResponse [ ^ ]，也可以在此处进行解释 [ ^ ].从版本10开始可用.
另外，业务对象提供的手册 [

What version are you using?
It is pretty hard to say what you are doing wrong. But here are some websites and articles that might help you find the problem, and perhaps an alternative for what you are currently doing (shouldn''t you use ExportToHttpResponse?).
I am assumung oRpt is a ReportDocument Object[^]?
MSDN has a link on the ReportDocument.Export Method[^] which is available since version 10.
And it seems ReportDocument.ExportToDisk[^] is even easier to use and is supported since version 9.
To export to a http response there is a likewise method, called ExportToHttpResponse[^] which is also explained here[^]. This is available since version 10.
Also, the manual provided by business objects[^] seems pretty comprehensive. Starting on page 191 the export options are discussed in detail. Things get more interesting around page 210 though.

Hope it helps! :)
