C # Asp.Net Create a text file, zip it and save it to Blob - Without writing anything to disk

Difficult here, well for me anyway :)

Basically, I would like to create text, attach this text file in two directories, and then load it into the MySQL blob field - all without writing to disk. I'm relatively new to this, so any pointers are really appreciated. This is what I have gathered so far; it obviously crashes and burns, but I hope it gives a better idea of ​​what id is. Oh and them using DotNetZip now :)

public void broadcastItem()
        {
            System.IO.MemoryStream ms = new System.IO.MemoryStream();
            System.IO.StreamWriter sw = new System.IO.StreamWriter(ms);
            System.IO.MemoryStream ms2 = new System.IO.MemoryStream();
            sw.Write("Some Text generated and placed in a file");
            sw.Close(); //Text File Now Created

            using (ZipFile zip = new ZipFile())
            {

                zip.AddDirectory(@"Directory1\Directory2");
                //Zipping within two directories
                ZipEntry e = zip.AddEntry("Test", ms);
                e.
                e.Comment = "The content for entry in the zip file was obtained from a stream";
                zip.Comment = "This zip was created at " + System.DateTime.Now.ToString("G");
                zip.Save(ms2); //Trying to save to memory stream
            }

            try
            {
                OdbcConnection Server = new OdbcConnection("DSN=CentralServer");
                Server.Open();
                OdbcCommand DbCommand = Server.CreateCommand();
                DbCommand.CommandText = "INSERT INTO blobtest(blobfield) VALUES(?)";
                OdbcParameter param = new OdbcParameter("@file", SqlDbType.Binary);
                param.Value = ms2;
                DbCommand.Parameters.Add(param);
                DbCommand.ExecuteNonQuery();
                //Trying to save zip file from memory stream to blob field


            }
            catch (Exception ex)
            {
                throw ex;
            }
        }

** EDIT - move closer ***

Now I can create a text file and fix it in memory, the problem is that the text does not appear in the file - that is, its empty, I now have the file in two directories :)

modified code below

public void test3()
        {
            MemoryStream ms = new MemoryStream();
            StreamWriter sw = new StreamWriter(ms);

            sw.WriteLine("HELLO!");
            sw.WriteLine("I WANT TO SAVE THIS FILE AS A .TXT FILE WITHIN TWO FOLDERS");
            ms.Position = 0;

            // create the ZipEntry archive from the xml doc store in memory stream ms
            MemoryStream outputMS = new System.IO.MemoryStream();

            ZipOutputStream zipOutput = new ZipOutputStream(outputMS);
            ZipEntry ze = new ZipEntry(@"Directory1\Directory2\example.txt");
            zipOutput.PutNextEntry(ze);
            zipOutput.Write(ms.ToArray(), 0, Convert.ToInt32(ms.Length));
            zipOutput.Finish();
            zipOutput.Close();

            byte[] byteArrayOut = outputMS.ToArray();
            outputMS.Close();
            ms.Close();
            try
            {
                OdbcConnection rstServer = new OdbcConnection("DSN=CentralServer");
                Server.Open();
                OdbcCommand DbCommand = Server.CreateCommand();
                DbCommand.CommandText = "INSERT INTO blobtest(blobfield) VALUES(?)";
                OdbcParameter param = new OdbcParameter("@file", SqlDbType.Binary);
                param.Value = byteArrayOut;
                DbCommand.Parameters.Add(param);
                DbCommand.ExecuteNonQuery();
                Response.Write(byteArrayOut.ToString());


            }

            catch (Exception ex)
            {
                Response.Write(ex.ToString());
            }
        }
