Pls try below. thanks

AttachmentName = CType(item.Attachments.FirstOrDefault, Attachment).Name

Number = item.subject.split(β€œ/β€œc)(0).replace(”[EXT] β€œ,””)
Code = item.subject.split("/"c)(2)

SubjectFInal = Number+Code

if(SubjectFInal = AttachmentName)

Hi @kirankumar.mahanthi1
this expression is not working
every time subject line changes with attachments.


mm there is no fixed subject i guess. if we get multiple attachments in that case how many codes we would get in subject.

Hi @kirankumar.mahanthi1
can you make this using activities in uipath ?

Not fixed codes(attachements).

subject line compares with only pdf file format

A rough shot, only checking the number part could look like this:


(From x In myMail.Attachments.Where(Function (x) x.Name.toUpper.EndsWith(".PDF"))
Let srx = Regex.Match(myMail.Subject,"\d+")
Let nrx = Regex.Match(x.Name,"\d+")
Where {srx.Success,nrx.Success}.All(Function (c1) c1)
Where srx.Value.Equals(nrx.Value)).Count > 0
  • filtering out all attachments, taking only pdfs
  • extract the number from subject and attachment name
  • continue when both regexes did succeed
  • check if both numbers are matching

ensure System.Text.RegularExpressions is added to the imports (close to the variable panel)

we can adopt or change to:

  • incorporating also to check the CN, BL, XXX Tokens
  • Filtering out the relevant / matching Attachment Filenames
