将文件保存到ftp服务器

Question

我正在asp.net和c#中创建一个文件上传器.我只是想将上传的文件直接保存到ftp服务器.可能吗？如果可能,我该如何设置ftp服务器身份验证信息.

(127.0.0.1只是一个例子.我无法编写真正的ip.我必须使用HTTP协议获取文件.我们的一些客户ISP不支持ftp.这是主要问题.)

protected void submit_button_Click(object sender, EventArgs e)
    {
        string filename = Path.GetFileName(upload_file.FileName);
        string fileExt = Path.GetExtension(upload_file.FileName);

        if (fileExt == ".csv")
        {
            string folder = Server.MapPath("ftp://127.0.0.1/uploads/");
                upload_file.SaveAs(folder + "/" + filename);
                ltr.Text = "Successful.";
        }
        else
        {
            upload_file.BorderColor = System.Drawing.Color.Red;
            ltr.Text = "File type must be .csv.";
        }
    }

它非常简单.下面的方法只传入文件名.显然,更改StreamReader中的目录.

编辑:对不起只是注意到你说你的客户端不支持FTP所以以下不会工作.

public bool ftpTransfer(string fileName)
{
    try
    {
        string ftpAddress = "127.0.0.1";
        string username = "user";
        string password = "pass";

        using (StreamReader stream = new StreamReader("C:\\" + fileName))
        {
            byte[] buffer = Encoding.Default.GetBytes(stream.ReadToEnd());

            WebRequest request = WebRequest.Create("ftp://" + ftpAddress + "/" + "myfolder" + "/" + fileName);
            request.Method = WebRequestMethods.Ftp.UploadFile;
            request.Credentials = new NetworkCredential(username, password);
            Stream reqStream = request.GetRequestStream();
            reqStream.Write(buffer, 0, buffer.Length);
            reqStream.Close();
        }
        return true;
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex.ToString());
        return false;
    }
}

编辑:重写文件名.
