Sample Code:
C#
long filelength = 123456789;
StringBuilder sb = new StringBuilder ();
Explorer.StrFormatByteSize ( filelength, sb, 20 ); // this is not a magic number. I think 8 is the minimum
Console.WriteLine ( sb );
VB
''' <summary>
''' Returns a string representation of a number of bytes (ie. 524288 = "512Kb")

Private Function fnFileSize(ByVal size As Long) As String
Dim sb As New Text.StringBuilder(20)
StrFormatByteSize(size, sb, sb.Capacity)
Return sb.ToString()
End Function
