Converting CSV file data to Byte

I am working on an existing piece of VB.Net Code which is sending data from CSV file to FTP and over there they recreate the csv file.

How to read the variable data which is  in the Parameter. I want to ensure whether the variable data is carrying the actual values from CSV file in the Byte format.

ByVal data As Byte()

Public Function UploadFileFromStream(ByVal data As Byte(), ByVal fileName As String) As Boolean

        Try
            _ftpWebRequest = CType(WebRequest.Create(_uri & fileName), FtpWebRequest)
            _ftpWebRequest.Credentials = New System.Net.NetworkCredential(_userId, _password, _domain)
            _ftpWebRequest.KeepAlive = True
            _ftpWebRequest.UseBinary = _useBinary

            _ftpWebRequest.Method = System.Net.WebRequestMethods.Ftp.UploadFile

            Dim prxy As New System.Net.WebProxy()
            prxy.BypassProxyOnLocal = True
            _ftpWebRequest.Proxy = prxy

            Using request As System.IO.Stream = _ftpWebRequest.GetRequestStream()

                request.Write(data, 0, data.Length)
                request.Close()

            End Using

        Catch ex As Exception
            Throw New Exception(ex.Message)
        End Try

        Return True

    End Function

Huh? See Stream.Write.. so it should work.

But why don't you use a stream instead?

Hi chokka;

See if this gives you what you are looking for.

Dim base64String As String 
base64String = System.Convert.ToBase64String(binaryData, 0, binaryData.Length)

@Fernado, What variable is that binaryData

Visual Studio Intellisense points me to change it to BinaryReader or BinaryWriter

This piece of syntax helped me. Your syntax doesn't returned the  actual value. Indeed, it was displaying the value in an encrypted  or some binary format.

Dim str As String
str = System.Text.Encoding.UTF8.GetString(data)
