目前最新版本为2.2.3，下载后在bin目录中找到edtFTPnet.dll，在项目中添加引用。
下面为一些用法：
1、FTP服务器根目录为web，在它下面创建如下图示的目录和上传文件
FTPConnection.CommandEncoding = Encoding.GetEncoding("GBK") 指定GBK编码以支持中文文件名
FTPConnection.CreateDirectory() 创建指定目录
FTPConnection.ChangeWorkingDirectory() 切换到指定目录
FTPConnection.UploadFile() 上传文件
web
|-----L11
|-----L21
|-----L31
|-----31.htm
|-----21.htm
|-----L22
|-----11.htm
|-----目录.txt
private
const
string
ftpServerIP =
"xx.xx.xx.xx"
;
private
const
string
ftpRemotePath =
"web"
;
private
const
string
ftpUserID =
"user"
;
private
const
string
ftpPassword =
"123"
;
private
void
btnCreateAndUpload_Click(
object
sender, EventArgs e)
{
using
(
var
conn =
new
FTPConnection
{
ServerAddress = ftpServerIP,
ServerDirectory = ftpRemotePath,
UserName = ftpUserID,
Password = ftpPassword,
CommandEncoding = Encoding.GetEncoding(
"GBK"
)
})
{
conn.Connect();
//创建目录L11
conn.CreateDirectory(
"L11"
);
//============切换当前工作目录到L11============
conn.ChangeWorkingDirectory(
"L11"
);
//上行代码也可以用conn.ServerDirectory = "L11";
//上传"文档.txt"
conn.UploadFile(
"文档.txt"
,
"文档.txt"
);
//创建子目录L21,L22
conn.CreateDirectory(
"L21"
);
conn.CreateDirectory(
"L22"
);
//在当前工作目录L11上传文件"L11.htm"
conn.UploadFile(
"11.htm"
,
"11.htm"
);
//============切换当前工作目录到L21============
conn.ChangeWorkingDirectory(
"L21"
);
//上传文件21.htm
conn.UploadFile(
"21.htm"
,
"21.htm"
);
//创建目录L31
conn.CreateDirectory(
"L31"
);
//============切换当前工作目录到L31============
conn.ChangeWorkingDirectory(
"L31"
);
//上传文件31.htm
conn.UploadFile(
"31.htm"
,
"31.htm"
);
}
}

2、获取文件信息
FTPConnection.GetFileInfos() 获取文件和目录详细信息，结果的一个属性Dir为true表示为目录，否则为文件
private
void
btnList_Click(
object
sender, EventArgs e)
{
using
(
var
conn =
new
FTPConnection
{
ServerAddress = ftpServerIP,
ServerDirectory = ftpRemotePath,
UserName = ftpUserID,
Password = ftpPassword,
CommandEncoding = Encoding.GetEncoding(
"GBK"
)
})
{
conn.Connect();
//获取指定目录的所有子目录和文件信息
conn.ChangeWorkingDirectory(
"L11/L21"
);
var
files1 = conn.GetFileInfos();
ShowFileInfos(files1);
/*结果如下：
File, /web/L11/L21/21.htm, 21.htm, 11.2KB, 2013-9-26 14:51:00
Dir, /web/L11/L21/L31, L31, 0KB, 2013-9-26 14:51:00
*/
////返回上级目录，例子中为web/L11
conn.ChangeWorkingDirectoryUp();
var
files2 = conn.GetFileInfosRecursive();
ShowFileInfos(files2);
/*结果如下：
File, /web/L11/11.htm, 11.htm, 59.4KB, 2013-9-26 14:51:00
Dir, /web/L11/L21, L21, 0KB, 2013-9-26 14:51:00
Dir, /web/L11/L22, L22, 0KB, 2013-9-26 14:51:00
File, /web/L11/文档.txt, 文档.txt, 40.8KB, 2013-9-26 14:51:00
File, /web/L11/L21/21.htm, 21.htm, 11.2KB, 2013-9-26 14:51:00
Dir, /web/L11/L21/L31, L31, 0KB, 2013-9-26 14:51:00
File, /web/L11/L21/L31/31.htm, 31.htm, 5.6KB, 2013-9-26 14:51:00
*/
}
}
void
ShowFileInfos(FTPFile[] files)
{
foreach
(
var
file
in
files)
{
string
info =
string
.Format(
"{0}, {1}, {2}, {3}KB, {4}"
,
file.Dir ?
"Dir"
:
"File"
, file.Path, file.Name, Math.Round(file.Size / 1024.0, 1), file.LastModified);
richTextBox1.AppendText(info +
"\r\n"
);
}
richTextBox1.AppendText(
"\r\n"
);
}

其中递归获取指定目录的所有子目录和文件信息的扩展方法GetFileInfosRecursive如下：
public
static
class
FtpClientExtensions
{
/// <summary>
/// 递归获取目录的所有子目录和文件信息
/// </summary>
public
static
FTPFile[] GetFileInfosRecursive(
this
FTPConnection conn)
{
var
resultList =
new
List<FTPFile>();
var
fileInfos = conn.GetFileInfos();
resultList.AddRange(fileInfos);
foreach
(
var
fileInfo
in
fileInfos)
{
if
(fileInfo.Dir)
{
conn.ServerDirectory = fileInfo.Path;
resultList.AddRange(conn.GetFileInfosRecursive());
}
}
return
resultList.ToArray();
}
/// <summary>
/// 递归删除目录(包括所有子目录和文件信息)
/// </summary>
public
static
void
DeleteDirectoryRecursive(
this
FTPConnection conn,
string
directoryName)
{
conn.ChangeWorkingDirectory(directoryName);
var
fileInfos = conn.GetFileInfos();
foreach
(
var
fileInfo
in
fileInfos)
{
if
(fileInfo.Dir)
conn.DeleteDirectoryRecursive(fileInfo.Name);
else
conn.DeleteFile(fileInfo.Name);
}
conn.ChangeWorkingDirectoryUp();
conn.DeleteDirectory(directoryName);
}
}
|
3、删除目录及所有子目录和文件
FTPConnection.DeleteDirectory()当删除的目录不为空时，会出错，需递归删除，
递归删除目录扩展方法DeleteDirectoryRecursive见上面类FtpClientExtensions
private
void
btnDelete_Click(
object
sender, EventArgs e)
{
using
(
var
conn =
new
FTPConnection
{
ServerAddress = ftpServerIP,
ServerDirectory = ftpRemotePath,
UserName = ftpUserID,
Password = ftpPassword,
CommandEncoding = Encoding.GetEncoding(
"GBK"
)
})
{
conn.Connect();
//递归删除目录及所有子目录和文件
conn.DeleteDirectoryRecursive(
"L11"
);
//如果删除单个文件，路径为当前目录的相对路径
//conn.DeleteFile("L11/11.htm");
}
}
