How to Compress Files in ASP.NET?

Hi,
I don’t know How to Compress Files in ASP.NET. While net suffering I found one “myasp.net”. Here I get some knowledge. Can anyone any other idea.

'GZip object that compress the file
Dim myStreamZip As New GZipStream(myCompressedFile, CompressionMode.Compress)

'Write Back
myStreamZip.Write(myBuffer, 0, myBuffer.Length)
myStreamZip.Close()
Me.lblResult.Text = """" + strName lblResult.Text = lblResult.Text + " was compressed &uploaded successfully."

What we do here is read the file into a stream, change its extension to the appropriate GZ ext, and compress using the GZipStream compression method.
