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.

ExportToStream 函数返回一个Stream.然后，您可以使用此流写入文件.有关详细信息，请参阅此答案:如何将流保存到C# 中的文件?
The ExportToStream function returns a Stream. You can then use this stream to write a file.See this answer for details : How do I save a stream to a file in C#?
