Hi,
I am have on table which stores uploaded file with guid and file also saved with guid name.
I want to send this file as attachment. When I send file as it is in attachment with guid name then it is working fine.(below code works great)

C#

Attachment attachResource = new Attachment(Server.MapPath("/public/_pdf/" + strFILEGUID + ".pdf"));
mail.Attachments.Add(attachResource);

But i want to send this file with some different name so i used below code.

C#

System.IO.MemoryStream data = new System.IO.MemoryStream();
System.IO.Stream str = File.OpenRead(Server.MapPath("/public/_pdf/" + strFILEGUID  + ".pdf"));
str.CopyTo(data);
data.Seek(0, SeekOrigin.Begin);
byte[] buf = new byte[data.Length];
data.Read(buf, 0, buf.Length);
Attachment attachResource = new Attachment(data, "ChangedFileName" + ".pdf");
mail.Attachments.Add(attachResource);

This code send file with name 'ChangedFileName.pdf' but while opening file it says file is damaged. I am not getting the problem here. Any help will be appreciated.
Thanks

Solution 1

Use BinaryReader to read the PDF File

System.IO.BinaryReader bw = new BinaryReader(str);

byte[] buf = bw.ReadBytes((int)str.Length);

Thanks
