Dear All,

I use System.IO.Compression namespace  for compressing file
give me overflow for streamObj.Length when file size more then 3 GB.

following my code:

        Dim streamObj As Stream = File.OpenRead(GZipFileName)
       Dim buffer(streamObj.Length) As Byte

       streamObj.Read(buffer, 0, buffer.Length)
       streamObj.Close()

       Dim compFile As System.IO.FileStream =
File.Create((Path.ChangeExtension(GZipFileName, "GZip")))
       Dim zipStreamObj As New GZipStream(compFile,
CompressionMode.Compress)

       zipStreamObj.Write(buffer, 0, buffer.Length)
       zipStreamObj.Close()

Thanks,

Harshad
