C# FTP over SSL问题

我在通过SSL将文件上载到ftp站点到特定目录时遇到问题。为此，我正在使用

System.Net.FtpWebRequest

类。上传进展顺利。但是该文件总是被放到主目录中。你知道什么地方做错了吗？谢谢你的帮助

    public bool UploadFile(string srcFilePath, string destFilePath = null)
    {
        if (String.IsNullOrWhiteSpace(srcFilePath))
            throw new ArgumentNullException("Source FilePath.");

        if (String.IsNullOrWhiteSpace(destFilePath))
            destFilePath = Path.GetFileName(srcFilePath);

        Uri serverUri = GetUri(destFilePath);

        //// the serverUri should start with the ftp:// scheme.
        if (serverUri.Scheme != Uri.UriSchemeFtp)
            return false;

        // get the object used to communicate with the server.
        FtpWebRequest request = CreateFtpRequest(serverUri, WebRequestMethods.Ftp.UploadFile);

        // read file into byte array
        StreamReader sourceStream = new StreamReader(srcFilePath);
        byte[] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());
        sourceStream.Close();
        request.ContentLength = fileContents.Length;

        // send bytes to server
        Stream requestStream = request.GetRequestStream();
        requestStream.Write(fileContents, 0, fileContents.Length);
        requestStream.Close();

        FtpWebResponse response = (FtpWebResponse)request.GetResponse();
        Debug.WriteLine("Response status: {0} - {1}", response.StatusCode, response.StatusDescription);

        return true;
    }

    private FtpWebRequest CreateFtpRequest(Uri serverUri, string method)
    {
        FtpWebRequest request = (FtpWebRequest)WebRequest.Create(serverUri);
        request.EnableSsl = true;
        request.UsePassive = true;
        request.UseBinary = true;
        request.KeepAlive = true;
        request.Credentials = new NetworkCredential(_userName, _password);
        request.Method = method;
        return request;
    }

    private Uri GetUri(string remoteFilePath)
    {
        return new Uri(_baseUri, remoteFilePath);
    }

嗯。我终于明白了。这是.NET4.0框架问题。使用.NET3.5构建解决方案，效果非常好

讨厌在微软新发布的.NET中看到bug，浪费大量的时间来解决问题。
如果不显示您的代码，就不可能有人能帮助您。

当您在这里调试这行代码时
Uri serverUri=GetUri（destFilePath）
serverUri的确切值是多少？
ftp路径解析为正确的路径。但是文件被传送到了
