远程服务器返回错误：（550）文件不可用（错误发生于使ftp目录） [英] The remote server returned an error: (550) File unavailable(Error occured on making ftp directory)

问题描述

我开发一个WPF应用程序，我想做出使用C＃有不同的用户名FTP目录，如果它已经存在，然后将其保存在现有目录中的文件。

I am developing a wpf application and I want to make a directory on ftp using C# with different usernames and if it already exists then save files on existing directory.

我已经成功地创建检查现有目录的逻辑，但在创建新的目录，我得到了在运行时异常：

I've successfully created the logic of checking the existing directory but while creating a new directory I've got an exception on runtime:

远程服务器返回错误：（550）文件不可用（例如，未找到文件，没有访问权限）

我在网上查了不同的解决方案，而且大多数是说，这是由于写权限。我分配的FTP文件夹的写权限，但我仍然有问题。请帮助？

I've checked different solutions on the internet and most are saying that it is due to write permissions. I am assigning the ftp folder write permissions, but I am still having the problem. Please Help?

下面是我的code：

    static void CreateFtpFolder(string source)
    {
        FtpWebRequest request = (FtpWebRequest)FtpWebRequest.Create(source);
        request.Credentials = new NetworkCredential(ftpusername, ftppassword);
        request.Method = WebRequestMethods.Ftp.MakeDirectory;
        request.UsePassive = true;
        request.UseBinary = false;
        request.KeepAlive = false;
        request.Proxy = null;

        FtpWebResponse ftpResp = request.GetResponse() as FtpWebResponse;

    }

我有关于误差 FtpWebResponse 。

推荐答案

您code看起来很好.......你是说你已经分配的权限了。 唯一的问题是，你可能会传递一个错误的源，这是造成problem..Check您的源字符串可能有一个错误......

Your code look fine.......you are saying that you have assigned permission too. The only problem is that you may be passing a wrong "Source"which is causing problem..Check your source string it may have an error......

路径应

 WebRequest request = WebRequest.Create("ftp://host.com/directory123");

这意味着目录将与名为directory12创建 如果您要指定这样的路径

it mean directory will be created with name "directory12" if your are specifying path like this

 WebRequest request = WebRequest.Create("ftp://host.com/directory123/directory1234");

这意味着 ftp://host.com/directory123/ 应该已经存在，新目录将被命名为directory1234创建 希望这将有助于

this mean "ftp://host.com/directory123/" should already exist and new directory will be created with name "directory1234" hope it will help
