I need to upload files using streaming. when a user selected a file in browser it is converted to stream
is is done as follows.


client side code:

if (FileUpload1.HasFile)
        { 
            System.IO.FileInfo fileInfo = new System.IO.FileInfo(FileUpload1.PostedFile.FileName);
            FileTrasferServiceReference.TransferServiceClient clientUpload = new TransferServiceClient();
            using (System.IO.FileStream stream = new System.IO.FileStream(FileUpload1.PostedFile.FileName, System.IO.FileMode.Open, System.IO.FileAccess.Read))
            {                
                clientUpload.UploadFile(stream); 
            }
        } 

Wcf Service side code:

public void UploadFile(System.IO.Stream FileByteStream)
    {
        FileStream targetStream = null;
        Stream sourceStream =  FileByteStream;

        string uploadFolder = @"C:\upload\";
        //string filename = request.FileMetaData.Filename;
        string filePath = Path.Combine(uploadFolder, "xyz.zip");

        using (targetStream = new FileStream(filePath, FileMode.Create, FileAccess.Write, FileShare.None))
        {
            //read from the input stream in 4K chunks
            //and save to output stream
            const int bufferLen = 4096;
            byte[] buffer = new byte[bufferLen];
            int count = 0;
            while ((count = sourceStream.Read(buffer, 0, bufferLen)) > 0)
            {
                targetStream.Write(buffer, 0, count);
            }
            targetStream.Close();
            sourceStream.Close();
        }

    } 

the files are not being uploaded, is the above code correct or wrong? if not correct can some one provide sample code of it.
