Question

c# .net ftp方式创建文件夹

通过ftp打开一个服务器，判断是否有这个文件夹，如果没有则创建的最简代码，谢谢。
注意别给我过多的冗余代码，也别复制什么本地创建，那些都不是我想要的，我要的是通过ftp创建，谢谢。
楼下的不懂不要乱说行不行？推荐答案中根本就是错误的，百度人也太不负责了。

Answer 1

//上传文件

public static Boolean FtpUpload(string ftpPath,string localFile)

{

//检查目录是否存在，不存在创建

FtpCheckDirectoryExist(ftpPath);

FileInfo fi = new FileInfo(localFile);

FileStream fs = fi.OpenRead();

long length = fs.Length;

FtpWebRequest req = (FtpWebRequest)WebRequest.Create(ftpServerIP + ftpPath + fi.Name);

req.Credentials = new NetworkCredential(ftpUserID, ftpPassword);

req.Method = WebRequestMethods.Ftp.UploadFile;

req.ContentLength = length;

req.Timeout = 10 * 1000;

try

{

Stream stream = req.GetRequestStream();

int BufferLength = 2048; //2K

byte[] b = new byte[BufferLength];

int i;

while ((i = fs.Read(b, 0, BufferLength)) > 0)

{

stream.Write(b, 0, i);

}

stream.Close();

stream.Dispose();

}

catch (Exception e)

{

ErrLog(e.Message + e.StackTrace);

return false;

}

finally

{

fs.Close();

req.Abort();

}

req.Abort();

return true;

}

//判断文件的目录是否存,不存则创建

public static void FtpCheckDirectoryExist(string destFilePath)

{

string fullDir = FtpParseDirectory(destFilePath);

string[] dirs = fullDir.Split('/');

string curDir = "/";

for (int i = 0; i < dirs.Length; i++)

{

string dir = dirs[i];

//如果是以/开始的路径,第一个为空

if (dir != null && dir.Length > 0)

{

try

{

curDir += dir + "/";

FtpMakeDir(curDir);

}

catch (Exception)

{}

}

}

}

public static string FtpParseDirectory(string destFilePath)

{

return destFilePath.Substring(0, destFilePath.LastIndexOf("/"));

}

//创建目录

public static Boolean FtpMakeDir(string localFile)

{

FtpWebRequest req = (FtpWebRequest)WebRequest.Create(ftpServerIP + localFile);

req.Credentials = new NetworkCredential(ftpUserID, ftpPassword);

req.Method = WebRequestMethods.Ftp.MakeDirectory;

try

{

FtpWebResponse response = (FtpWebResponse)req.GetResponse();

response.Close();

}

catch (Exception)

{

req.Abort();

return false;

}

req.Abort();

return true;

}

Answer 3

Directory.CreateDirectory("路径")

太没诚意了
