c# - 为什么 FtpWebRequest 将用户登录添加为目标数据集的一部分？

Question

我最近使用 C# 将 Windows cmd 转换为 FtpWebRequest，以将文件上传到 IBM 大型机数据集。 Look here。

运行两者时，我发现它们上传到不同的数据集，而它们应该完全相同，FtpWebRequest 正在将用户登录信息添加到数据集。

cmd 上的代码将文件上传到:'ABCD.AA.C58FC.ABC1FD.ZP3ABC' 数据集，C# 代码将文件上传到:USERME.ABCD.AA.C58FC .ABC1FD.ZP3ABC。我需要 C# 代码上传到数据集:ABCD.AA.C58FC.ABC1FD.ZP3ABC。我知道他们正在上传到不同的数据集，因为在使用 C# 上传文件后，如果我使用 cmd 来获取文件，例如:

get 'ABCD.AA.C58FC.ABC1FD.ZP3ABC' examplefile`

没有给我任何东西，但如果我这样做:

get 'USERME.ABCD.AA.C58FC.ABC1FD.ZP3ABC' examplefile`

我拿到了文件。我在这里缺少什么？

这是 Windows cmd:

Open abc.wyx.state.aa.bb
User
Pass
lcd c:\Transfer>
Put examplefile 'ABCD.AA.C58FC.ABC1FD.ZP3ABC'
close
bye

此处 C# 使用 FtpWebRequest

string ftpfullpath = @"ftp://abc.wyx.state.aa.bb/'ABCD.AA.C58FC.ABC1FD.ZP3ABC'";            
try
{

    FtpWebRequest ftp = (FtpWebRequest)FtpWebRequest.Create(ftpfullpath);
    ftp.Credentials = new NetworkCredential(user, password);

    ftp.KeepAlive = true;
    ftp.UseBinary = false;  //Use ascii.              

    ftp.Method = WebRequestMethods.Ftp.UploadFile;

    FileStream fs = File.OpenRead(source);
    byte[] buffer = new byte[fs.Length];
    fs.Read(buffer, 0, buffer.Length);
    fs.Close();

    Stream ftpstream = ftp.GetRequestStream();
    ftpstream.Write(buffer, 0, buffer.Length);
    ftpstream.Close();
}

这是来自 C# 的网络日志:

Answer 1

用单引号将 C# 中的文件名括起来。

我知道为什么会发生这种情况(因为 TSO/ISPF 会用用户 ID 预先创建一个创建的文件名)，但我不知道为什么在你的情况下会发生这种情况(除非 C# 的东西认为这是必要的)但这就是解决问题的方法。

好的，我看到您(可能)已经这样做了，这似乎意味着 C# 正在剥离它们。因此，您需要“保护”您给出的明显单引号。

一些主要镜头:

"'abcd.efg.hij'"
"''abcd.efg.hij''"
''abcd.efg.hij''

你明白了。

有 C# 内容的文档吗？
