System.Net命名空间下的FtpWebRequest类实现了ftp协议的.Net实现。
- FtpWebRequest.KeepAlive指定在请求完成后服务器是否要马上关闭连接
- FtpWebRequest.UseBinary 指定文件以二进制方式传输
- FtpWebRequest.Method设置ftp的命令
- WebRequestMethods.Ftp.UploadFile是上传文件的命令
使用FtpWebRequest对象上传文件时,需要向GetRequestStream方法返回的Stream中写入数据。
需要引用如下命名空间
using System.Net;
using System.IO;
FTP上传文件代码实现:
public void ftpfile(string ftpfilepath, string inputfilepath)
{
string ftphost = "127.0.0.1";
//here correct hostname or IP of the ftp server to be given
string ftpfullpath = "ftp://" + ftphost + ftpfilepath;
FtpWebRequest ftp = (FtpWebRequest)FtpWebRequest.Create(ftpfullpath);
ftp.Credentials = new NetworkCredential("userid", "password");
//userid and password for the ftp server to given
ftp.KeepAlive = true;
ftp.UseBinary = true;
ftp.Method = WebRequestMethods.Ftp.UploadFile;
FileStream fs = File.OpenRead(inputfilepath);
byte[] buffer = new byte[fs.Length];
fs.Read(buffer, 0, buffer.Length);
fs.Close();
Stream ftpstream = ftp.GetRequestStream();
ftpstream.Write(buffer, 0, buffer.Length);
ftpstream.Close();
}
调用方法:
ftpfile(@"/testfolder/testfile.xml", @"c: estfile.xml");
