ftpwebrequest

问题 Aright, so here's how it goes I'm trying to set a up a polling system to pull log files from several laser systems each with their own ftp. However, I'm running into difficulty when attempting to call the FtpWebResponse call to download the log file the following is the code I'm using: // Get the object used to communicate with the server. FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://192.168.10.140/param.dat"); request.Method = WebRequestMethods.Ftp.DownloadFile; request

问题 I've multiple files on a ftp server.I do not know the names of these files except that they are all. xml files. How do I programmatically download these files using .Net's FtpWebRequest? Thanks. 回答1: Most likely you'll have to issue a Dir command that lists out all the files, then go through each one downloading it. Here is some info on getting a directory listing. http://msdn.microsoft.com/en-us/library/ms229716.aspx 回答2: Take a look at the ListDirectory function. It's the equivalent of the

问题 I need to download some files via ftp from an old AS/400 server. My code looks more or less like: FtpWebRequest _request = (FtpWebRequest)WebRequest.Create("ftp://ftpaddress/FOO.CSV"); _request.Credentials = new NetworkCredential(_ftpUsername, _ftpPassword); _request.Method = WebRequestMethods.Ftp.DownloadFile; FtpWebResponse response = (FtpWebResponse)_request.GetResponse(); However, an exception is being thrown with the message: 501 Character (/) not allowed in object name. I'm guessing the

问题 In my application, I have files in FTP server one directory and I move that file source to target path. In this process, when I move selected source file that source file will not show in the source path, it will show only in target path. I tried this below code, but I am getting error: string sourceurl = "ftp://ftp.com/Mainfoder/Folder1/subfolder/subsubfolder/" string Targetpat = "ftp://ftp.com/Mainfoder/DownloadedFiles/"+subfolder+"/"+todaydatefolder+"/"+susubfolder; Uri serverFile = new

问题 I need to list thousands of files on FTP server, and delete the necessary ones. As you can guess, performance is essential, so I need a way to reuse the FTP connection. There is not enough explanation on MSDN about the connection usage of FtpWebRequests! It only says "Multiple FtpWebRequests reuse existing connections, if possible." What does "if possible" mean? I want to control when to close connection, simple as that! Any idea? Regards 回答1: Previous connections to the server are reused if

问题 I keep getting a exception when I try to FTP to my Win 2008 Server from C# code using VS2008 as debugger. My test class looks like this: public class FTP { private string ftpServerIP = "192.168.10.35:21"; private string ftpUserID = "Administrator"; private string ftpPassword = "XXXXXXXX"; private string uploadToFolder = "uploadtest"; public void Upload(string filename) { FileInfo fileInf = new FileInfo(filename); string uri = "ftp://" + ftpServerIP + "/" + uploadToFolder + "/" + fileInf.Name;

问题 My below code works perfectly fine in my computer without proxy. But in client server they need to add proxy to the FTP client (FileZilla) to be able to access the FTP. But When I add proxy it says SSL cannot be enabled when using a proxy. FTP proxy var proxyAddress = ConfigurationManager.AppSettings["ProxyAddress"]; WebProxy ftpProxy = null; if (!string.IsNullOrEmpty(proxyAddress)) { var proxyUserId = ConfigurationManager.AppSettings["ProxyUserId"]; var proxyPassword = ConfigurationManager

问题 I use below codes to get files from a FTP site. It works in my computer, but it only return HTML codes when I run it on another computer (I can see that the HTML are codes of web page when I access FTP via browser). What's wrong? public String GetFilesAsString(string folder,string fileExtension) { StringBuilder result = new StringBuilder(); FtpWebRequest reqFTP; try { String ftpserver = ftp + folder+"/"; reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri(ftpserver)); reqFTP.UsePassive =

问题 I am using below code (C# .NET 3.5) to upload a file: FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://someweb.mn/altanzulpharm/file12.zip"); request.Method = WebRequestMethods.Ftp.UploadFile; request.KeepAlive = true; request.UseBinary = true; request.Credentials = new NetworkCredential(username, password); FileStream fs = File.OpenRead(FilePath); byte[] buffer = new byte[fs.Length]; fs.Read(buffer, 0, buffer.Length); fs.Close(); Stream ftpstream = request.GetRequestStream();

问题 Can someone tell me how to change directories using FtpWebRequest? This seems like it should be an easy thing to do, but I'm not seeing it. EDIT I just want to add...I don't have my heart set on FtpWebRequest. If there's a better (easier) way to do FTP in .NET please let me know. Apparently there's no way to do it using a live connection, you need to change the uri to trick ftpwebrequest into using a different request (thanks Jon). So I'm looking for a 3rd party client...
