File Compress and File Upload

/// Upload a file......
string strName;
strName = System.IO.Path.GetFileName(fileUpload.PostedFile.FileName);

try {
this.lblResult.Text = strName + " was uploaded successfully.";
catch (Exception ex)
{ this.lblResult.Text = "An Error Occured While Uploading File.";}


/// Compress and Upload the file ...
string strName = Path.GetFileName(fileUpload.PostedFile.FileName);

//Create a stream object to read the file.
Stream myStream = fileUpload.PostedFile.InputStream;
byte[] myBuffer = new byte[myStream.length];

//Read the file using the Stream object and fill the buffer.
myStream.Read(myBuffer, 0, myBuffer.Length);
FileStream compresFile;
compresFile = File.Create(Server.MapPath(Path.ChangeExtension(strName, "gz")));

// Write from the buffer containing the file contents to the gzip file using the GZipStream object
GZipStream myStreamZip = new GZipStream(compresFile, CompressionMode.Compress);
myStreamZip.Write(myBuffer, 0, myBuffer.Length);
