或者使用VS的包管理器也可以方便安装此组件：
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");
}
