将文件移到FTP上的父文件夹 [英] Move file to parent folder on FTP

问题描述

我以前在移动文件时遇到问题，与绝对路径和相对路径有关 RenameTo 属性。我目前得到了553错误（文件名不允许）。

文件位于// blah / John / Update / Done /，我想移动到//../ Update /。

以下是我正在使用的代码片段：

  string ftpConn =ftp：// blah / John / Update /; 
 for（int i = 0; i< fileList.Count; i ++）
 {
 var requestMove =（FtpWebRequest）WebRequest.Create（ftpConn +Done /+ fileList [i] .fName）; 
 requestMove.Method = WebRequestMethods.Ftp.Rename; 
 requestMove.Credentials = new NetworkCredential（ftpUser，ftpPass）; 
 requestMove.RenameTo =... / John / Update /+ fileList [i] .fName; 
 requestMove.GetResponse（）; 
} 
  

我试着改变 RenameTo 属性到绝对路径，它仍然给我同样的错误。

解决方案

我不认为 ... 在相对路径中有效。
您可能意思是：
$ b

  requestMove.RenameTo =./../ + fileList [i] .fName; 
 // ^ ^ 
 //当前目录──┘│
 //│
 //上一个文件夹──┘
  

如果您当前的工作目录是 / blah / John / Update / Done / ， ./../ 有效地代表 / blah / John / Update 。

详细了解相对路径语法此处 。

I'm trying to move files from a folder into it's parent folder.

I had issues moving files before, something to do with absolute versus relative path on the RenameTo property. I'm currently getting a 553 error(file name not allowed).

Files are in "//blah/John/Update/Done/" and I'd like to move to "//../Update/".

Here is a snippet of the code I'm using:

string ftpConn="ftp://blah/John/Update/";
for (int i = 0; i < fileList.Count; i++ )
{
    var requestMove = (FtpWebRequest)WebRequest.Create(ftpConn + "Done/" + fileList[i].fName);
    requestMove.Method = WebRequestMethods.Ftp.Rename;
    requestMove.Credentials = new NetworkCredential(ftpUser, ftpPass);                   
    requestMove.RenameTo = ".../John/Update/" + fileList[i].fName;
    requestMove.GetResponse();
}

I've tried changing the RenameTo property to the absolute path and it still gives me the same error.

解决方案

I don't think ... is valid in relative paths. You probably meant:

requestMove.RenameTo = "./../" + fileList[i].fName;
//                      ^  ^
//        Current dir ──┘  │
//                         │
//      Go up one folder ──┘

If your current working directory is /blah/John/Update/Done/, ./../ effectively represents /blah/John/Update.
