FTP Problems

Hi All,

I've finally got this one worked out. I was calling my recursive function in the wrong place, and effectively overwriting the directory structure I was building. Here is the completed, working code which I hope will help someone else who might be struggling with a similar problem.

 

string whichdir = @"";
buildDirectories(whichdir);

List dirs = FileHelper.GetFilesRecursive(@"");
foreach (string p in dirs)
{

StringBuilder builder2 = new StringBuilder(p);
builder2.Remove(0, 38);
builder2.Replace('\\', '/');

FtpWebRequest request = (FtpWebRequest)WebRequest.Create(new Uri("ftp://" + builder2));
request.Timeout = 10000;
request.ReadWriteTimeout = 10000;
request.UseBinary = true;
request.KeepAlive = true;
request.Method = WebRequestMethods.Ftp.UploadFile;

FileInfo uploadFile = new FileInfo(p);
request.ContentLength = uploadFile.Length;
int buffLength = 2048;
byte[] buff = new byte[buffLength];
int contLength;

FileStream fStream = uploadFile.OpenRead();

Stream requestWriter = request.GetRequestStream();
contLength = fStream.Read(buff, 0, buffLength);

while (contLength != 0)
{
requestWriter.Write(buff, 0, buffLength);
contLength = fStream.Read(buff, 0, buffLength);
}

requestWriter.Close();
fStream.Close();
}
}


public static void buildDirectories(String whichDir)
{
DirectoryInfo dirInfo = new DirectoryInfo(whichDir);

foreach (DirectoryInfo d in dirInfo.GetDirectories())
{

StringBuilder builder = new StringBuilder(d.FullName.ToString());
builder.Remove(0, 38);
builder.Replace('\\', '/');

FtpWebRequest createDirs = WebRequest.Create("ftp://" + builder + "/") as FtpWebRequest;
createDirs.Method = WebRequestMethods.Ftp.MakeDirectory;
createDirs.KeepAlive = false;
createDirs.UseBinary = true;

using (var response = (FtpWebResponse)createDirs.GetResponse())
{
writer.WriteLine(response.StatusCode);
response.Close();
}

buildDirectories(d.FullName.ToString());
}
}

 

I've made some progress on this. It turns out if I create the subdirectories manually on the server before uploading then everything works fine. So I wrote code to recreate the subdirectories on the server, and that works. However, that doesn't cover the next level of subdirectories. When the code gets to that level I have the same problem I originally reported.

I'm currently working on a recursive function to build the entire directory structure on the server before uploading any files, and am running into problems with that. It will build the first directory then die with the same 550 error originally reported. I'm writing the paths that the buildDirectories() function creates out to file for debugging, and it is correctly capturing the directories and all subdirectories. I'd be grateful for any feedback. Here is my code:

public static void buildDirectories(String whichDir)
{
DirectoryInfo dirInfo = new DirectoryInfo(whichDir);

foreach (DirectoryInfo d in dirInfo.GetDirectories())
{

StringBuilder builder = new StringBuilder(d.FullName.ToString());
builder.Remove(0, 38);
builder.Replace('\\', '/');
writer.WriteLine(builder);

FtpWebRequest createDirs = WebRequest.Create("ftp:///" + builder + "/") as FtpWebRequest;
createDirs.Method = WebRequestMethods.Ftp.MakeDirectory;
createDirs.KeepAlive = true;
createDirs.UseBinary = true;

buildDirectories(d.FullName.ToString());

using (var response = (FtpWebResponse)createDirs.GetResponse())
{
writer.WriteLine(response.StatusCode);
}
}
}
