如何使用C＃代码将.txt文件从一个服务器上传到Ftp服务器到另一个文件夹到另一个文件夹 [英] How Can I Upload .Txt Files To Ftp Server From One Server To Folder To The Other Folder Using C# Code

问题描述

以下是将文件上传到ftp服务器的代码，但它显示我找不到文件异常



FileInfo fileInf = new FileInfo（filename）;





string uri =ftp：//+ ftpServerIP + path; // +/+ fileInf.Name; //





FtpWebRequest reqFTP;

reqFTP = （FtpWebRequest）FtpWebRequest.Create（new Uri（ftp：//+ ftpServerIP + path +/+ filename））; ///+ awb +

reqFTP.Credentials = new NetworkCredential（ftpUserID，ftpPassword）;

reqFTP.KeepAlive = false;

reqFTP.Method = WebRequestMethods.Ftp.UploadFile;

reqFTP.UseBinary = true;

reqFTP.Proxy = null;



reqFTP.ContentLength = fileInf.Length;



//缓冲区大小设置为2kb

int buffLength = 2048;

byte [] buff = new byte [buffLength];

int contentLen;



//打开文件流（System.IO.FileStream）来读取要上传的文件

FileStream fs = fileInf.OpenRead（）;



//使用（FileStream stream = File.Open（@D：\ SSIMFROMFTPServer \，FileMode.Create ））;



//写入要上传的文件的流

Stream strm = reqFTP.GetRequestStream（）;



//测试

// FileStream writeStream = new FileStream（localDestnDir +/+ strm，FileMode.Create）;



//一次从文件流中读取2kb

contentLen = fs.Read（buff，0，buffLength）;



// Till Stream内容结束

while（contentLen！= 0）

{

//将内容从文件流写入FTP上传流

strm.Write（buff，0，contentLen）;

contentLen = fs.Read（buff，0，buffLength）;

}

//关闭文件流和请求流

strm.Close（ ）;

fs.Close（）;

The below is code for uploading files to the ftp server but it shows me file not found exception

FileInfo fileInf = new FileInfo(filename);


string uri = "ftp://" + ftpServerIP + path; //+ "/" + fileInf.Name;//


FtpWebRequest reqFTP;
reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri("ftp://" + ftpServerIP + path + "/" + filename));//"/" + awb +
reqFTP.Credentials = new NetworkCredential(ftpUserID, ftpPassword);
reqFTP.KeepAlive = false;
reqFTP.Method = WebRequestMethods.Ftp.UploadFile;
reqFTP.UseBinary = true;
reqFTP.Proxy = null;

reqFTP.ContentLength = fileInf.Length;

// The buffer size is set to 2kb
int buffLength = 2048;
byte[] buff = new byte[buffLength];
int contentLen;

// Opens a file stream (System.IO.FileStream) to read the file to be uploaded
FileStream fs = fileInf.OpenRead();

// using (FileStream stream = File.Open(@"D:\SSIMFROMFTPServer\", FileMode.Create));

// Stream to which the file to be upload is written
Stream strm = reqFTP.GetRequestStream();

//test
// FileStream writeStream = new FileStream(localDestnDir + "/" + strm, FileMode.Create);

// Read from the file stream 2kb at a time
contentLen = fs.Read(buff, 0, buffLength);

// Till Stream content ends
while (contentLen != 0)
{
// Write Content from the file stream to the FTP Upload Stream
strm.Write(buff, 0, contentLen);
contentLen = fs.Read(buff, 0, buffLength);
}
// Close the file stream and the Request Stream
strm.Close();
fs.Close();

推荐答案

使用WinSCP;



namespace Project

{

class Upload_Files

{

public void upload_file_sftp（）

{

试试

{



SessionOptions sessionOptions = new SessionOptions

{



Protocol = Protocol.Sftp，

HostName =abc.com，

UserName = abc，

密码=1234，

PortNumber = 22，

SshHostKeyFingerprint =ssh-rsa 1024 a7：20：03 ：28：19：3C：88：4C：05：3F：CF：C3 ：15：ad：57：20



};





使用（Session session = new Session（））

{

;



session.Open（sessionOptions ）; $





TransferOptions transferOptions = new TransferOptions（）;

transferOptions.TransferMode = TransferMode.Binary;









TransferOperationResult transferResult;

transferResult = session.PutFiles（@P：\ File_upload，/ name_of_sftpfolder /，false，transferOptions）;





transferResult.Check（）;







foreach（transferRventArgs transfer in transferResult.Transfers）

{

MessageBox.Show（上传文件+ transfer.FileName +成功）;





transferResult.Transfers.Count（）;





}





}







}

catch（exception ex）

{

MessageBox.Show（例外：+ ex.Message）;

}





}

}

}



注意：对于上面的代码，你需要添加winscp dll和exe。

using WinSCP;

namespace Project
{
class Upload_Files
{
public void upload_file_sftp()
{
try
{

SessionOptions sessionOptions = new SessionOptions
{

Protocol = Protocol.Sftp,
HostName = "abc.com",
UserName = "abc",
Password = "1234",
PortNumber = 22,
SshHostKeyFingerprint = "ssh-rsa 1024 a7:20:03:28:19:3c:88:4c:05:3f:cf:c3:15:ad:57:20"

};


using (Session session = new Session())
{
;

session.Open(sessionOptions);


TransferOptions transferOptions = new TransferOptions();
transferOptions.TransferMode = TransferMode.Binary;




TransferOperationResult transferResult;
transferResult = session.PutFiles(@"P:\File_upload","/name_of_sftpfolder/", false, transferOptions);


transferResult.Check();



foreach (TransferEventArgs transfer in transferResult.Transfers)
{
MessageBox.Show("Upload of files " + transfer.FileName + " succeeded");


transferResult.Transfers.Count();


}


}



}
catch (Exception ex)
{
MessageBox.Show("Exception: " + ex.Message);
}


}
}
}

Note: For above code u need to add winscp dll and exe.
