Hi,
I'm looking to find out how I can tell if a filename contains two or more dots

eg. 45FGG.TESTDOC.MAY12.zip

I want to end up splitting the filename into two parts

45FGG.TESTDOC.MAY12

.zip

I can do it for one dot using LastIndexOf, but more than two dots I'm stuck

Thanks
J

Solution 1

How about this:

VB

Dim s as sting= "45FGG.TESTDOC.MAY12.zip"
Dim result() as string
result = s.Split(".")

result.count-2 should the give you the number of . in the text :)

VB

Dim strFileName As String = "45FGG.TESTDOC.MAY12.zip"

VB

Dim FileNameArray() As String = strFileName.Split(".") "

VB

Dim ArrayLength As Integer = FileNameArray.Length
Dim FileNameExtension As String = FileNameArray(ArrayLength -1) '.zip 
Dim FileNameExtensionLength As Integer =  FileNameExtension.Length
Dim FileNameLength As Integer = strFileName.Length - FileNameExtensionLength
Dim FileName As String = Strings.Left(strFileName, FileNameLength) '45FGG.TESTDOC.MAY12
