 ‘ Create an instance of UnicodeEncoding
 Dim objUnicodeEncoding As New UnicodeEncoding()

    ‘ Create array of string variables.
   Dim strMyText As Byte() = _
  
 objUnicodeEncoding.GetBytes("File Management using Whidbey/VB.NET")
      
 objMemoryStream.Write(strMyText, 0 , strMyText.Length)

 MessageBox.Show(“ _
      "Capacity = {0}, “ _
  “Length = {1}, “ _
  “Position = {2}", _
           objMemoryStream.Capacity.ToString(), _
           objMemoryStream.Length.ToString(), _
           objMemoryStream.Position.ToString())

Catch
 MessageBox.Show(“Error in File Operation”)
End Try
