使用C＃上传文件到FTP
我尝试使用C＃将file upload到FTP服务器。 该file upload，但零字节。
private void button2_Click(object sender, EventArgs e) { var dirPath = @"C:/Documents and Settings/sander.GD/Bureaublad/test/"; ftp ftpClient = new ftp("ftp://example.com/", "username", "password"); string[] files = Directory.GetFiles(dirPath,"*.*"); var uploadPath = "/httpdocs/album"; foreach (string file in files) { ftpClient.createDirectory("/test"); ftpClient.upload(uploadPath + "/" + Path.GetFileName(file), file); } if (string.IsNullOrEmpty(txtnaam.Text)) { MessageBox.Show("Gelieve uw naam in te geven !"); } } 现有的答案是有效的，但为什么WebClient已经实现了FTP上传整洁的WebRequesttypes的重新发明和打扰：
using (WebClient client = new WebClient()) { client.Credentials = new NetworkCredential(ftpUsername, ftpPassword); client.UploadFile("ftp://ftpserver.com/target.zip", "STOR", localFilePath); }
public void UploadFtpFile(string folderName, string fileName) { FtpWebRequest request; try { string folderName; string fileName; string absoluteFileName = Path.GetFileName(fileName); request = WebRequest.Create(new Uri(string.Format(@"ftp://{0}/{1}/{2}", "127.0.0.1", folderName, absoluteFileName))) as FtpWebRequest; request.Method = WebRequestMethods.Ftp.UploadFile; request.UseBinary = 1; request.UsePassive = 1; request.KeepAlive = 1; request.Credentials = new NetworkCredential(user, pass); request.ConnectionGroupName = "group"; using (FileStream fs = File.OpenRead(fileName)) { byte[] buffer = new byte[fs.Length]; fs.Read(buffer, 0, buffer.Length); fs.Close(); Stream requestStream = request.GetRequestStream(); requestStream.Write(buffer, 0, buffer.Length); requestStream.Flush(); requestStream.Close(); } } catch (Exception ex) { } }
如何使用
UploadFtpFile("testFolder", "E:\\filesToUpload\\test.img");
在你的foreach中使用这个
你只需要一次创build文件夹
创build一个文件夹
request = WebRequest.Create(new Uri(string.Format(@"ftp://{0}/{1}/", "127.0.0.1", "testFolder"))) as FtpWebRequest; request.Method = WebRequestMethods.Ftp.MakeDirectory; FtpWebResponse ftpResponse = (FtpWebResponse)request.GetResponse();
以下为我工作：
public virtual void Send(string fileName, byte[] file) { ByteArrayToFile(fileName, file); var request = (FtpWebRequest) WebRequest.Create(new Uri(ServerUrl + fileName)); request.Method = WebRequestMethods.Ftp.UploadFile; request.UsePassive = false; request.Credentials = new NetworkCredential(UserName, Password); request.ContentLength = file.Length; var requestStream = request.GetRequestStream(); requestStream.Write(file, 0, file.Length); requestStream.Close(); var response = (FtpWebResponse) request.GetResponse(); if (response != null) response.Close(); }
你不能读取代码中的文件参数，因为它只是文件名。
使用以下内容：
byte[] bytes = File.ReadAllBytes(dir + file);
要获取文件，可以将其传递给Send方法。
public static void UploadFileToFtp(string url, string filePath, string username, string password) { var fileName = Path.GetFileName(filePath); var request = (FtpWebRequest)WebRequest.Create(url + fileName); request.Method = WebRequestMethods.Ftp.UploadFile; request.Credentials = new NetworkCredential(username, password); request.UsePassive = true; request.UseBinary = true; request.KeepAlive = false; using (var fileStream = File.OpenRead(filePath)) { using (var requestStream = request.GetRequestStream()) { fileStream.CopyTo(requestStream); requestStream.Close(); } } var response = (FtpWebResponse)request.GetResponse(); Console.WriteLine("Upload done: {0}", response.StatusDescription); response.Close(); }
在这里find它： http : //www.snippetsource.net/Snippet/127/upload-a-file-with-ftp-in-c
在第一个例子中，必须将其更改为：
requestStream.Flush(); requestStream.Close();
首先冲洗，然后closures。
这适用于我，这种方法将SFTP文件到networking中的位置。 它使用SSH.NET.2013.4.7库。一个可以免费下载。
//Secure FTP public void SecureFTPUploadFile(string destinationHost,int port,string username,string password,string source,string destination) { ConnectionInfo ConnNfo = new ConnectionInfo(destinationHost, port, username, new PasswordAuthenticationMethod(username, password)); var temp = destination.Split('/'); string destinationFileName = temp[temp.Count() - 1]; string parentDirectory = destination.Remove(destination.Length - (destinationFileName.Length + 1), destinationFileName.Length + 1); using (var sshclient = new SshClient(ConnNfo)) { sshclient.Connect(); using (var cmd = sshclient.CreateCommand("mkdir -p " + parentDirectory + " && chmod +rw " + parentDirectory)) { cmd.Execute(); } sshclient.Disconnect(); } using (var sftp = new SftpClient(ConnNfo)) { sftp.Connect(); sftp.ChangeDirectory(parentDirectory); using (var uplfileStream = System.IO.File.OpenRead(source)) { sftp.UploadFile(uplfileStream, destinationFileName, true); } sftp.Disconnect(); } }
使用.NET框架将file upload到FTP服务器的最简单的方法是使用WebClient.UploadFile方法 ：
WebClient client = new WebClient(); client.Credentials = new NetworkCredential("username", "password"); client.UploadFile("ftp://ftp.example.com/remote/path/file.zip", @"C:\local\path\file.zip");
如果你需要更好的控制， WebClient不提供（如TLS / SSLencryption等），使用FtpWebRequest 。 简单的方法是使用Stream.CopyTo将FileStream复制到FTPstream：
FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://ftp.example.com/remote/path/file.zip"); request.Credentials = new NetworkCredential("username", "password"); request.Method = WebRequestMethods.Ftp.UploadFile; using (Stream fileStream = File.OpenRead(@"C:\local\path\file.zip")) using (Stream ftpStream = request.GetRequestStream()) { fileStream.CopyTo(ftpStream); }
如果您需要监控上传进度，则必须自行将文件复制到内容中：
FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://ftp.example.com/remote/path/file.zip"); request.Credentials = new NetworkCredential("username", "password"); request.Method = WebRequestMethods.Ftp.UploadFile; using (Stream fileStream = File.OpenRead(@"C:\local\path\file.zip")) using (Stream ftpStream = request.GetRequestStream()) { byte[] buffer = new byte[10240]; int read; while ((read = fileStream.Read(buffer, 0, buffer.Length)) > 0) { ftpStream.Write(buffer, 0, read); Console.WriteLine("Uploaded {0} bytes", fileStream.Position); } }
对于GUI进度（WinForms ProgressBar ），请参阅C＃示例：
我们如何显示进度条上传与FtpWebRequest
如果您想上传文件夹中的所有文件，请参阅
使用WebClient上传文件的目录 。
我观察到 –
- FtpwebRequest丢失。
- 由于目标是FTP，所以需要NetworkCredential。
我准备了一个像这样工作的方法，可以用参数TargetDestinationPathreplacevariablesftpurl的值。 我在WinForms应用程序上testing了这个方法：
private void UploadProfileImage(string TargetFileName, string TargetDestinationPath, string FiletoUpload) { //Get the Image Destination path string imageName = TargetFileName; //you can comment this string imgPath = TargetDestinationPath; string ftpurl = "ftp://downloads.abc.com/downloads.abc.com/MobileApps/SystemImages/ProfileImages/" + imgPath; string ftpusername = krayknot_DAL.clsGlobal.FTPUsername; string ftppassword = krayknot_DAL.clsGlobal.FTPPassword; string fileurl = FiletoUpload; FtpWebRequest ftpClient = (FtpWebRequest)FtpWebRequest.Create(ftpurl); ftpClient.Credentials = new System.Net.NetworkCredential(ftpusername, ftppassword); ftpClient.Method = System.Net.WebRequestMethods.Ftp.UploadFile; ftpClient.UseBinary = true; ftpClient.KeepAlive = true; System.IO.FileInfo fi = new System.IO.FileInfo(fileurl); ftpClient.ContentLength = fi.Length; byte[] buffer = new byte[4097]; int bytes = 0; int total_bytes = (int)fi.Length; System.IO.FileStream fs = fi.OpenRead(); System.IO.Stream rs = ftpClient.GetRequestStream(); while (total_bytes > 0) { bytes = fs.Read(buffer, 0, buffer.Length); rs.Write(buffer, 0, bytes); total_bytes = total_bytes - bytes; } //fs.Flush(); fs.Close(); rs.Close(); FtpWebResponse uploadResponse = (FtpWebResponse)ftpClient.GetResponse(); string value = uploadResponse.StatusDescription; uploadResponse.Close(); }
