问题
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"));
I tried this:
rep1.ExportToStream(ExportFormatType.PortableDocFormat);
rep1.SaveAs(Server.MapPath("Modbus.pdf"));
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.

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#?
