Answer 2

code here:

    public class GetFileFromServer
    {
        private  FTPConnection ftpConnection;
        public void connect(string host, string user, string pass)
        {
            ftpConnection = new FTPConnection();
            ftpConnection.ServerAddress = host;
            ftpConnection.UserName = user;
            ftpConnection.Password = pass;
            ftpConnection.Connect();
        }
        public void close()
        {
            ftpConnection.Close();
        }

        public List<string> downloadWebsite(string rootFolder, string pathTarget, List<string> logErr )//string host, string user, string pass,
        {
            //FTPConnection ftpConnection = new FTPConnection();
            //ftpConnection.ServerAddress = host;
            //ftpConnection.UserName = user;
            //ftpConnection.Password = pass;
            //ftpConnection.Connect();

            List<FTPFile> listFilesAndFolder = ftpConnection.GetFileInfos(rootFolder).ToList();
            List<FTPFile> lisFolders = new List<FTPFile>();
            foreach (FTPFile ftpFile in listFilesAndFolder)
            {
                if (ftpFile.Dir)
                {
                    lisFolders.Add(ftpFile);
                }
                else
                {
                    string s = pathTarget + @"\" + ftpFile.Name;
                    string s1 = rootFolder + @"/" + ftpFile.Name;
                    long fileSizeOnDisk = checkExistsFileOnDisk(pathTarget, ftpFile.Name);
                    if (fileSizeOnDisk == -1 || fileSizeOnDisk != ftpFile.Size)
                    {
                        try
                        {
                            if (ftpConnection.Exists(rootFolder + @"/" + ftpFile.Name))
                            {
                                //if (ftpFile.Size > 100000000)
                                //{

Answer 3

The code looks fine to me. Does this happen when you're debugging or when you run outside the debugger? Is your code built as Debug or release? It might be an idea to enable logging at the debug level and post relevant portions of the log.

Answer 4

when the exception occurs, I can not see where that error (stack trace = {Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack.}). I run the debug unit tests. (can you give me your email address, I will send my code to you)

Answer 5

I run debug errors here:(FTPClient.cs)

BytesTransferred(this, new BytesTransferredEventArgs(remoteFile, lastBytesTransferred, resumeMarker));

catch (Exception ex)

log.Error("Caught exception " + ex.Message) = {Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack.}

Answer 6

Have you tried it on other computers? You should also try to change the platform in the project settings.

Answer 7

I think this is a bug of the library, not by the computer, I try using CuteFTP download, completely normal.two errors I often encounter when using the library to download is: {Unable to evaluate expression v

Answer 8

I'm curious about this:

timeout 2147483647 ms


Do you set the timeout yourself?

Answer 9

I try to increase the timeout, see how results.but the error still occurs:

public void connect(string host, string user, string pass)
{
ftpConnection = new FTPConnection();
ftpConnection.ServerAddress = host;
ftpConnection.UserName = user;
ftpConnection.Password = pass;
ftpConnection.Timeout = Int32.MaxValue; // I add this line......
//ftpConnection.ConnectMode = FTPConnectMode.ACTIVE;
ftpConnection.Connect();
FTPConnection.LogLevel = LogLevel.All;
FTPConnection.LogFile = "log.dat";
}

Answer 10

timeout default:

public void connect(string host, string user, string pass)
{
ftpConnection = new FTPConnection();
ftpConnection.ServerAddress = host;
ftpConnection.UserName = user;
ftpConnection.Password = pass;
ftpConnection.Connect();
FTPConnection.LogLevel = LogLevel.All;
FTPConnection.LogFile = "log.dat";
}
