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

[csharp] view plain copy print ?

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

[csharp] view plain copy print ?

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：

[csharp] view plain copy print ?

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);
}
}
