ASP.net Adding a timestame to File name

Hello,
I would like to add time stamp to file name in following format.

imagename200907011905.jpg
imagename200907011905.tiff


My problem is that the extension is always different.
How do I separate extension and append time stamp?
I would like to store it in database, so I would like to know the variable name, store procedure as well.

I'm using ASP.NET VB and SQL server 2008 express edition.

Thank you


Dim myfilename As String
        Dim currentTime As String = "0000".Substring(0, 4 - DateTime.Now.Year.ToString().Length) & DateTime.Now.Year.ToString() & "00".Substring(0, 2 - DateTime.Now.Month.ToString().Length) & DateTime.Now.Month.ToString() & "00".Substring(0, 2 - DateTime.Now.Day.ToString().Length) & DateTime.Now.Day.ToString() & "00".Substring(0, 2 - DateTime.Now.Hour.ToString().Length) & DateTime.Now.Hour.ToString() & "00".Substring(0, 2 - DateTime.Now.Minute.ToString().Length) & DateTime.Now.Minute.ToString() & "00".Substring(0, 2 - DateTime.Now.Second.ToString().Length) & DateTime.Now.Second.ToString()
        myfilename = FileField.PostedFile.FileName & currentTime
        Dim c As String = System.IO.Path.GetFileName(myfilename)
        Try
            FileField.PostedFile.SaveAs(Server.MapPath("~/blog/" + c))
            Span1.InnerHtml = "File upload successful."
        Catch ex As Exception
 
        End Try

There may be a better way, but I would do it like this (see code snippit)
		Dim myfilename As String
		Dim currentTime As String = Format(Now, "yyyyMMddHHmm")
		Dim myFileParts() As String
 
		myFileParts = Split(FileField.PostedFile.FileName, ".")
		If myFileParts.Length > 1 Then
			myfilename = myFileParts(0) & currentTime & "." & myFileParts(1)
		Else
			myfilename = FileField.PostedFile.FileName & currentTime
		End If
		Dim c As String = System.IO.Path.GetFileName(myfilename)
		Try
			FileField.PostedFile.SaveAs(Server.MapPath("~/blog/" + c))
			Span1.InnerHtml = "File upload successful."
		Catch ex As Exception
 
		End Try

Use System.IO.Path functionality to get detail.

Dim myfilename As String
Dim strExtension As String
Dim strTimeStamp As String
strTimeStamp = DateTime.Now.ToString("yyyyMMddhhmm")
myfilename = System.IO.Path.GetFileNameWithoutExtension(FileField.FileName)
strExtension = System.IO.Path.GetExtension(FileField.FileName)
Dim fullname As String = myfilename + strTimeStamp + strExtension
Try
FileField.PostedFile.SaveAs(Server.MapPath("~/blog/" + fullname))
Span1.InnerHtml = "File upload successful."
Catch ex As Exception
End Try

yep. either way works, except I like the 24-hour date format (HH) as opposed to the 12 (hh).
