在一个会话中将多个文件上载到FTp服务器 [英] Upload Multiple Files to a FTp server within one session
本文介绍了在一个会话中将多个文件上载到FTp服务器的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
您好，
我需要将多个文件上传到ftp服务器，我试图使用Webrequest一次发送每个文件，问题是每次我发送我需要添加凭据的文件，这意味着我打开了一个新会话。我尝试了不同的方法，但它不起作用，低于我最新的。有谁知道如何优雅地做到这一点？我需要一次发送文件，所以我不能使用异步。有人可以帮我吗？
private void envoiFTP（ string table）
{
string path = @ D：\Temp \;
//
string [] files = Directory.GetFiles（path， @ * .xml）;
if （files！= null ）
{
foreach （字符串文件 个文件）
{
fi = new FileInfo（file）;
string fileName = fi.Name;
string fileurl = path + @ / + fileName;
string ftpFile = FtpServer + @ / + fileName;
FtpWebRequest myRequest =（FtpWebRequest）FtpWebRequest.Create（ftpFile）;
myRequest.Credentials = new NetworkCredential（FtpUser，FtpPassword）;
myRequest.Method = WebRequestMethods.Ftp.UploadFile;
myRequest.Timeout = 1000000 ;
myRequest.UseBinary = true ;
myRequest.KeepAlive = true ;
myRequest.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 = myRequest.GetRequestStream（）;
while （total_bytes > 0 ）
{
bytes = fs.Read（buffer， 0 ，buffer.Length）;
rs.Write（buffer， 0 ，bytes）;
total_bytes = total_bytes - bytes;
}
fs.Close（）;
rs.Close（）;
FtpWebResponse uploadResponse =（FtpWebResponse）myRequest.GetResponse（）;
uploadResponse.Close（）;
}
}
}
}

嗨试试下面代码在FTP服务器上传文件
private void Upload144P_Click（对象发送者） ，EventArgs e）
{
OpenFileDialog fileobj = new OpenFileDialog（）;
fileobj.Filter =电影文件（* .mp4）| * .mp4 |网络电影文件（* .webm）| * .webm |所有文件（*。*）| *。*;
//fileobj.InitialDirectory =C：\\\ \\ ;;
//fileobj.Filter =视频文件（* .mp4）;
//fileobj.ShowDialog（）;
if（fileobj.ShowDialog（）== DialogResult.OK）
{
if（fileobj.CheckFileExists）
{
string test = Properties.Settings.Default.Connection;
SqlConnection con = new SqlConnection（test）;
con。打开（）;
string corr ectfilename = System.IO.Path.GetFileName（fileobj.FileName）;
SqlCommand cmd = new SqlCommand（Insert into Path（ID，Path5）VALUES（（select isnull（MAX（id），0 ）来自Path的+ 1，'\\Videos \\+ correctfilename +'），con）;
cmd.ExecuteNonQuery（）;
//对于进度条
DataTable dt = new DataTable（）;
timer5.Enabled = true;
string path = Application.StartupPath.Substring（0，Application.StartupPath.Length - 10）;
con.Close（）;
string uploadfile = fileobj.FileName;
string uploadFileName = new FileInfo（uploadfile）.Name;
string uploadUrl = ftp://ftp.infotech.com/;
FileStream fs = new FileStream（uploadfile，FileMode.Open，FileAccess.Read）;
try
{
long FileSize = new FileInfo（uploadfile）.Length; //正在上传的文件的文件大小。
Byte [] buffer = new Byte [FileSize];
fs.Read（buffer， 0，buffer.Length）;
fs.Close（）;
fs = null;
string ftpUrl = string.Format（{0} / {1}，uploadUrl，uploadFileName）;
FtpWebRequest requestObj = FtpWebRequest.Create（ftpUrl）as FtpWebRequest;
requestObj .Method = WebRequestMethods.Ftp.UploadFile;
requestObj.Credentials = new NetworkCredential（test@infotech.com，test @ 123）;
Stream requestStream = requestObj.GetRequestStream（）;
requestStream.Write（buffer，0，buffer.Length）;

}

Hello,
I need to upload multiple files to an ftp server, i tried to send each file a time using Webrequest, the problem is that each time I send a file i need to add credentials , which means i open up a new session. I tried different approach but it didn't work, below my latest. Does anyone have an idea how to do it gracefully? I need to send a file a time, so i can't use asynchronous. can anyone help me please ?
private void envoiFTP(string table) { string path = @"D:\Temp\"; // string[] files = Directory.GetFiles(path,@"*.xml"); if (files != null) { foreach (string file in files) { fi = new FileInfo(file); string fileName = fi.Name; string fileurl = path + @"/" + fileName; string ftpFile = FtpServer + @"/" + fileName; FtpWebRequest myRequest = (FtpWebRequest)FtpWebRequest.Create(ftpFile); myRequest.Credentials = new NetworkCredential(FtpUser, FtpPassword); myRequest.Method = WebRequestMethods.Ftp.UploadFile; myRequest.Timeout = 1000000; myRequest.UseBinary = true; myRequest.KeepAlive = true; myRequest.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 = myRequest.GetRequestStream(); while (total_bytes > 0) { bytes = fs.Read(buffer, 0, buffer.Length); rs.Write(buffer, 0, bytes); total_bytes = total_bytes - bytes; } fs.Close(); rs.Close(); FtpWebResponse uploadResponse = (FtpWebResponse)myRequest.GetResponse(); uploadResponse.Close(); } } } }解决方案Hi,

hi try this below code for upload file in FTP Server
private void Upload144P_Click(object sender, EventArgs e)
{
OpenFileDialog fileobj = new OpenFileDialog();
fileobj.Filter = "Movie files (*.mp4)|*.mp4|Web Movie files (*.webm)|*.webm|All files (*.*)|*.*";
//fileobj.InitialDirectory = "C:\\";
//fileobj.Filter = "Video files (*.mp4)";
//fileobj.ShowDialog();
if (fileobj.ShowDialog() == DialogResult.OK)
{
if (fileobj.CheckFileExists)
{
string test = Properties.Settings.Default.Connection;
SqlConnection con = new SqlConnection(test);
con.Open();
string correctfilename = System.IO.Path.GetFileName(fileobj.FileName);
SqlCommand cmd = new SqlCommand("Insert into Path(ID,Path5) VALUES ((select isnull(MAX(id),0) + 1 from Path),'\\Videos\\" + correctfilename + "')", con);
cmd.ExecuteNonQuery();
//For Progressbar
DataTable dt = new DataTable();
timer5.Enabled = true;
string path = Application.StartupPath.Substring(0, Application.StartupPath.Length - 10);
con.Close();
string uploadfile = fileobj.FileName;
string uploadFileName = new FileInfo(uploadfile).Name;
string uploadUrl = "ftp://ftp.infotech.com/";
FileStream fs = new FileStream(uploadfile, FileMode.Open, FileAccess.Read);
try
{
long FileSize = new FileInfo(uploadfile).Length; // File size of file being uploaded.
Byte[] buffer = new Byte[FileSize];
fs.Read(buffer, 0, buffer.Length);
fs.Close();
fs = null;
string ftpUrl = string.Format("{0}/{1}", uploadUrl, uploadFileName);
FtpWebRequest requestObj = FtpWebRequest.Create(ftpUrl) as FtpWebRequest;
requestObj.Method = WebRequestMethods.Ftp.UploadFile;
requestObj.Credentials = new NetworkCredential("test@infotech.com", "test@123");
Stream requestStream = requestObj.GetRequestStream();
requestStream.Write(buffer, 0, buffer.Length);
requestObj.Timeout = 1000000;
requestStream.Flush();
requestObj = null;
//requestObj.ConnectionGroupName = "MyGroupName";
//requestObj.KeepAlive = false;
//requestObj.ServicePoint.CloseConnectionGroup("MyGroupName");
requestObj.UsePassive = true;
requestObj.UseBinary = true;
requestObj.KeepAlive = false;
}
catch (Exception ex)
{
//MessageBox.Show("File upload/transfer Failed.\r\nError Message:\r\n" + ex.Message, "Succeeded", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
}
}
}
