Question

PLEASE NOTE, I have found a work around which actually works out better for me. That is to use the byte stream and decode rather than save at all. Therefore answers are non-essential but I would still be interested in any comments people have.

Having trouble with illegal characters in path. I have tried many different versions of the same thing, surely it’s just a path I need, and I’m fairly sure I know what one looks like! Can someone suggest what I may be doing wrong?

I am using http://hellowebapps.com/products/imapx/

Connection and everything else is okay!

Code:

            foreach (Message m in _imapClient.Folders["Football"].Messages)
            {
                m.Process();
                List<Attachment> attachment = m.Attachments;

                foreach (var a in attachment)
                {
                    a.SaveFile(@"C:\FileDrop\hello.csv");
                    //a.SaveFile(@"C:\FileDrop\");
                }
            }

The only way it seems to get around this is to get the string from the attachment data directly – using Encoding.GetString() with Convert.FromBase64String()

return _encoding.GetString(Convert.FromBase64String(contentStream));

Then just save the file as normal: MSDN
