我的ftp代码有什么问题？

Question

我在.NEt 2.0中使用c#来简单地尝试上传文件.代码中的一切似乎都没问题,但是当我从FtpWebRequest.GetRequestStream方法创建流时它仍然失败.

这是代码......

        FtpWebRequest ftpRequest;
        FtpWebResponse ftpResponse;

        try
        {
            string fileName = Path.GetFileName(strCompleteFilePath);
            ftpRequest = (FtpWebRequest)FtpWebRequest.Create(new Uri("ftp://myhost/" + fileName));
            ftpRequest.Method = WebRequestMethods.Ftp.UploadFile;
            ftpRequest.Proxy = null;
            ftpRequest.UseBinary = true;
            ftpRequest.Credentials = new NetworkCredential("myUserID", "myPW");
            ftpRequest.KeepAlive = false;

            FileInfo ff = new FileInfo(strCompleteFilePath);
            byte[] fileContents = new byte[ff.Length];

            using (FileStream fr = ff.OpenRead()) 
            {
                fr.Read(fileContents, 0, Convert.ToInt32(ff.Length));
            }

            using (Stream writer = ftpRequest.GetRequestStream())
            {
                writer.Write(fileContents, 0, fileContents.Length);
            }

            ftpResponse = (FtpWebResponse)ftpRequest.GetResponse(); 
        }

而错误....

您错过了路径中的/.

您将创建一个路径,ftp://myhostmyfile.txt如果您的文件名为"myfile.txt",我猜应该是ftp://myhost/myfile.txt

因此,只需在ftp://myhost字符串的末尾添加一个/ .
