在使用ftp上传一般使用
FtpWebRequest创建对象 执行对应操作
如下
FtpWebRequest reqFTP;
// 根据uri创建FtpWebRequest对象
reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri(uri));
// ftp用户名和密码
reqFTP.Credentials = new NetworkCredential(ftpUserID, ftpPassword);
// 默认为true,连接不会被关闭
// 在一个命令之后被执行
reqFTP.KeepAlive = false;
// 指定执行什么命令
reqFTP.Method = WebRequestMethods.Ftp.AppendFile;
// 指定数据传输类型
reqFTP.UseBinary = true;
// 上传文件时通知服务器文件的大小
reqFTP.ContentLength = fileInf.Length;
1.直接上传
在此需要使用req.FTP.Method = WebRequestMethods.Ftp.UploadFile;
2.断点续传(自己实现的,不知道是否科学)
在此需要使用req.FTP.Method = WebRequestMethods.Ftp.AppendFile;
但须先读取服务器上已存在的该文件的大小,上传时直接跳过该大小
利用此方法直接从后面继续读取文件即可
FileStream fs= fileInf.OpenRead();
fs.Seek(startfilesize, 0);
具体断点续传实现如下
public bool Upload(string filename, string ftpServerIP, string ftpUserID, string ftpPassword, ToolStripProgressBar pb,string path)
{
if (path == null)
path = "";
bool success = true;
FileInfo fileInf = new FileInfo(filename);
long allbye = (long)fileInf.Length;
if (fileInf.Name.IndexOf("#") == -1)
{
newFileName = QCKG(fileInf.Name);
}
else
{
newFileName = fileInf.Name.Replace("#", "#");
newFileName = QCKG(newFileName);
}
long startfilesize = GetFileSize(newFileName, ftpServerIP, ftpUserID, ftpPassword, path);
if (startfilesize >= allbye)
{
return false;
}
//startfilesize=0;
long startbye = startfilesize;
pb.Maximum = Convert.ToInt32(allbye);
pb.Minimum = Convert.ToInt32(startfilesize);
string uri;
if (path.Length == 0)
uri = "ftp://" + ftpServerIP + "/" + newFileName;
else
uri = "ftp://" + ftpServerIP + "/" + path + newFileName;
FtpWebRequest reqFTP;
// 根据uri创建FtpWebRequest对象
reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri(uri));
// ftp用户名和密码
reqFTP.Credentials = new NetworkCredential(ftpUserID, ftpPassword);
// 默认为true,连接不会被关闭
// 在一个命令之后被执行
reqFTP.KeepAlive = false;
// 指定执行什么命令
reqFTP.Method = WebRequestMethods.Ftp.AppendFile; (直接上传修改此处!)
// 指定数据传输类型
reqFTP.UseBinary = true;
// 上传文件时通知服务器文件的大小
reqFTP.ContentLength = fileInf.Length;
int buffLength = 2048;// 缓冲大小设置为2kb
byte[] buff = new byte[buffLength];
// 打开一个文件流 (System.IO.FileStream) 去读上传的文件
FileStream fs= fileInf.OpenRead();
try
{
// 把上传的文件写入流
Stream strm = reqFTP.GetRequestStream();
// 每次读文件流的2kb
fs.Seek(startfilesize, 0);(直接上传须去除该处)
int contentLen = fs.Read(buff, 0, buffLength);
// 流内容没有结束
while (contentLen != 0)
{
// 把内容从file stream 写入 upload stream
strm.Write(buff, 0, contentLen);
contentLen = fs.Read(buff, 0, buffLength);
startbye += contentLen;
pb.Value = Convert.ToInt32(startbye);
}
// 关闭两个流
strm.Close();
fs.Close();
}
catch
{
success = false;
}
return success;
}
