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");
- }
- }
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 + " ");
- }
- richTextBox1.AppendText(" ");
- }
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 + " "); } richTextBox1.AppendText(" "); }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);
- }
- }
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");
- }
- }
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"); } }
