如何在C#中将richtextbox内容直接存储到ftp

Guys这是在ftp上存储文件的代码。任何人都可以重新配置此代码，使其将richtextbox的内容存储在windows窗体中吗？我正在richtextbox上写任何东西，当我单击按钮时，它应该直接存储ftp。

{
    Stream requestStream = null;
    FileStream fileStream = null;
    FtpWebResponse uploadResponse = null;
    try
    {
        uploadUrl = "ftp://ftp.personalwebars.com/ATM/";
        fileName = txtTitle.Text + ".txt";
        FtpWebRequest uploadRequest = (FtpWebRequest)WebRequest.Create(uploadUrl + @"/" + fileName);
        uploadRequest.Method = WebRequestMethods.Ftp.UploadFile;
        //Since the FTP you are downloading to is secure, send
        //in user name and password to be able upload the file
        ICredentials credentials = new NetworkCredential(user, pswd);
        uploadRequest.Credentials = credentials;
        //UploadFile is not supported through an Http proxy
        //so we disable the proxy for this request.
        uploadRequest.Proxy = null;
        //uploadRequest.UsePassive = false; <--found from another forum and did not make a difference
        requestStream = uploadRequest.GetRequestStream();
        byte[] buffer = new byte[1024];
        int bytesRead;
        while (true)
        {
            bytesRead = fileStream.Read(buffer, 0, buffer.Length);
            if (bytesRead == 0)
                break;
            requestStream.Write(buffer, 0, bytesRead);
        }
        //The request stream must be closed before getting
        //the response.
        requestStream.Close();
        uploadResponse =
          (FtpWebResponse)uploadRequest.GetResponse();
        lblAuthentication.Text = "Your solution has been submitted in txt Mode. Thank You";
    }
    catch (WebException ex)
    {
    }
    finally
    {
        if (uploadResponse != null)
            uploadResponse.Close();
        if (fileStream != null)
            fileStream.Close();
        if (requestStream != null)
            requestStream.Close();
    }
}

public void Send(string url, string fileName, string content, string user, string password)
{
    byte[] bytes = Encoding.ASCII.GetBytes(content)
    var request = (FtpWebRequest) WebRequest.Create(new Uri(url + @"/" + fileName));
    request.Method = WebRequestMethods.Ftp.UploadFile;
    request.UsePassive = false;
    request.Credentials = new NetworkCredential(user, password);
    request.ContentLength = bytes.Length;
    var requestStream = request.GetRequestStream();
    requestStream.Write(bytes, 0, bytes.Length);
    requestStream.Close();
    var response = (FtpWebResponse) request.GetResponse();
    if (response != null) response.Close();
}
