如何在 C# 中使用 report.ExportToStream 函数

问题描述

我目前正在使用 c#.我需要将报告文件转换为 pdf 格式并通过邮件发送.我编写了编码及其工作.我使用 rpt.ExportToDisk(ExportFormatType) 进行转换.但这需要很长时间.谁能建议我，如何使用 ExportToStream 功能，这样我就可以避免前者，因为我不希望将报告文件存储在我的磁盘中.这是我正在工作的代码

I'm currently working in c#. I need to convert report file to pdf format and send it through mail. I wrote coding and its working. I use rpt.ExportToDisk(ExportFormatType) for conversion. But it takes long time. Can anyone please suggest me, how to use ExportToStream function, so that i can avoid former one as i dont want the report file to be stored in my disk. This is my code which is working

 rep1.Load(Server.MapPath("CrystalReport_ModbusNode.rpt"));
 rep1.ExportToDisk(ExportFormatType.PortableDocFormat,Server.MapPath("Modbus.pdf"));

我试过了:

rep1.ExportToStream(ExportFormatType.PortableDocFormat);
rep1.SaveAs(Server.MapPath("Modbus.pdf"));

但如果我使用这个，Modbus.pdf 仍然是 rpt 格式.ExportToStream id 没有做任何更改??如何发送邮件而不将其导出到我的磁盘.谁能帮我解决这个问题?提前致谢.

But if I use this, Modbus.pdf is still in rpt format. ExportToStream id not doing any changes?? How can I send mail, without exporting it to my disk. Can anyone help me to solve this issue? Thanks in advance.
