上传到FTP中的文件夹？

Question

我正在使用以下代码来学习如何使用FTP加载文件。如何设置文件上传路径或文件夹？

using System;
using System.IO;
using System.Net;
using System.Text;

namespace Examples.System.Net
{
    public class WebRequestGetExample
    {
        public static void Main ()
        {
            // 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("testfile.txt");
            byte [] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());
            sourceStream.Close();
            request.ContentLength = fileContents.Length;

            Stream requestStream = request.GetRequestStream();
            requestStream.Write(fileContents, 0, fileContents.Length);
            requestStream.Close();

            FtpWebResponse response = (FtpWebResponse)request.GetResponse();

            Console.WriteLine("Upload File Complete, status {0}", response.StatusDescription);

            response.Close();
            }
        }
    }
}

该文件夹是您设置在创建网址的一部分request："ftp://www.contoso.com/test.htm"。如果使用，"ftp://www.contoso.com/wibble/test.htm"则文件将被上传到名为的文件夹中wibble。

如果Method = WebRequestMethods.Ftp.MakeDirectory该wibble文件夹尚不存在，则可能需要先使用请求创建文件夹。
