Afternoon,

I am not sure how to use the split string to split a filename so that it writes the last 7 characters of the file name.

So for example my input would be "Smith and Co Account.pdf" and using the split string, output would be "Account"

Is someone able to help me finish this:

System.IO.Path.GetFileNameWithoutExtension(rfiles).Split

Open in new window



Please let me know if you have any question.

You could do the following:

Dim filename As String = System.IO.Path.GetFileNameWithoutExtension(rfiles)
Dim lastSeven As String = System.Text.RegularExpressions.Match(filename, ".{0, 7}$").Value

Open in new window


...where ".{0, 7}$" means between zero and seven ( {0, 7} ) of any character ( . ) that occurs at the end of the string ( $ ).

var str = String.Join("",System.IO.Path.GetFileNameWithoutExtension(rfiles).Skip(rfiles.Length-7).ToArray());

mystr = Right(System.IO.Path.GetFileNameWithoutExtension("c:\Users\test\Smith and Co Account.pdf"), 7)

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Dim FileName As String = System.IO.Path.GetFileNameWithoutExtension("c:\Users\test\Smith and Co Account.pdf")

Dim Result = FileName.Split(" ")(UBound(FileName.Split(" ")))

Neither of those give the last 7 characters; they both give the "word" following the last space in the filename.

You are very right, but i think this is the real requirement, as taking 7 last letters must be the example. If  the example was for instance "Smith and Co Acc.pdf" what sense would " Co Acc" make?
