How to remove extension from a Filename...

Question

_{Sunday, February 20, 2011 1:51 PM}

    Dim file5 As String

    Dim save As New SaveFileDialog

                    file5 = Path.GetFileName(save.FileName)

                    Dim file6 As String = Path.GetFileNameWithoutExtension(save.FileName)

                    Dim filepath As String

                    filepath = save.FileName.Remove(Val(save.FileName.Length) - Val(file5.Length), Val(save.FileName.Length)) + file6

                    TextBox1.Text = filepath

In my theory, this would work but I got this error:

  Error: Index and count must refer to a location within the string.

Parameter name: count

I'm trying to remove the extension from the Filename of the SaveFileDialog, is there a simpler way?

A simple example of using these functions to get to your desired goal.

    Dim save As New SaveFileDialog
    If save.ShowDialog() <> DialogResult.Cancel Then
      TextBox1.Text = System.IO.Path.Combine(System.IO.Path.GetDirectoryName(save.FileName), System.IO.Path.GetFileNameWithoutExtension(save.FileName))
    End If
