I would like to send CSV file via my FTP but my main method is throwing the following error - Argument 1: cannot convert from 'void' to 'System.IO.Stream'

C#
// Get the object used to communicate with the server.
            FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://www.contoso.com/test.htm");
            request.Method = WebRequestMethods.Ftp.UploadFile;

            // This example assumes the FTP site uses anonymous logon.
            request.Credentials = new NetworkCredential("anonymous", "janeDoe@contoso.com");

            // Copy the contents of the file to the request stream.
            StreamReader sourceStream = new StreamReader(createCSV());
            byte[] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());
            sourceStream.Close();
            request.ContentLength = fileContents.Length;


CSV method:
C#
public void createCSV()
        {
            string constr = ConfigurationManager.ConnectionStrings["#######"].ConnectionString;
            using (SqlConnection con = new SqlConnection(constr))
            {
                /// get data 
                            //Download the CSV file.
                            Response.Clear();
                            Response.Buffer = true;
                            Response.AddHeader("content-disposition", "attachment;filename=" + filename);
                            Response.Charset = "";
                            Response.ContentType = "application/text";
                            Response.Output.Write(csv);
                            Response.Flush();
                            Response.End();
                        }
                    }
                }
            }
        }


Please advice further. Thank you

I guess you need StreamWriter() looking at the line:
Response.Output.Write(csv);

Furthermore you method createCSV has void returntype in stead of a Stream or FileStream object.

1 solution

Um...
C#
StreamReader sourceStream = new StreamReader(createCSV());

C#
public void createCSV()

So you are trying to effectively do this:
C#
StreamReader s = new StreamReader(void);
And you expect that to compile?
I'm not sure exactly what that code is meant to do, but there is nothing there that even tries to deal with FTP: if you want to use FTP, then start by looking at teh FtpWebRequest class[^] or a prebuilt library such as Simple C# FTP Class[^]
