Check File SIze

I have written some code which uploads a file.

Before I upload the file I would like to check on the file size. If its below a certain limit I want to upload it else present the user with an error message.

Any Ideas ?

First I didn't check the code but it looks it should work .

VB Code:

Private Sub CheckFileSiz(ByVal File As String)
 
        'Parameters : File = provide full path 
 
        Dim Finfo As New IO.FileInfo(File)
        Dim Siz As Integer
 
        If IO.File.Exists(File) Then
            Siz = Finfo.Length
        Else
            Exit Sub
        End If
 
        Select Case Siz
 
            Case 100 '100k
                'Do this
 
            Case 200 '200 k
                'Do this
 
            Case 300 '300k
                'Do this
 
            Case Is <= 500 'k 
                'Do this
 
            Case Is <= 1000 'k 
                'Do this
 
        End Select
 
    End Sub
