使用C#的FTP(刷新当前目录) [英] FTP(Refresh current directory) using C#

问题描述

亲爱的，
我做了一个ftp文件浏览器，但不幸的是，当刷新当前目录为被动错误模式时，如果不输入它，它将无法正常工作.

Dear,
I have made a ftp file explorer but unfortunately it won''t work when refresh current directory passive false mode not enter.

private void bgworkerImporter_DoWork(object sender, DoWorkEventArgs e)
{
    BackgroundWorker worker = sender as BackgroundWorker;
    for (; ; )
    {
        if (IsbusyImporter == false)
        {
            //working here
           // ftpSession.CurrentDirectory.Refresh();
            StartDownload();
        }
        if ((worker.CancellationPending == true))
        {
            e.Cancel = true;
            break;
        }
        else
        {
            // Perform a time consuming operation and report progress.
            System.Threading.Thread.Sleep(500);
        }
    }
}

然后

then

public void StartDownload()
{
    //working here
    int files = ftpSession.CurrentDirectory.Files.Count();
    foreach (FtpFile file in ftpSession.CurrentDirectory.Files)
    {
      //  string Splitfile = file.Name.ToString();
      //  string[] Allsplitfile = Splitfile.Split('.');

        transferProgressBar.Value = 0;
        try
        {
            if (files >= 0)
            {
                // working here
                DownloadFile(file.Name.ToString());
                // Deletefile From FTP Directory
                if (IsSuccess == "Success")
                {
                    DeleteFTPFile(file.Name.ToString());
                }
            }
            else
            {
                IsbusyImporter = false;
            }


        }
        catch (Exception ex)
        {
            MessageBox.Show(IsDelete);
        }
    }
    IsbusyImporter = true;
   ftpSession.CurrentDirectory.Refresh();// here is problem refresh was not worked.

}

刷新当前目录不起作用，原因是为什么我的列表视图保留了先前删除的文件并创建了异常.
请告诉问题是什么.我正在尝试很多.如果您不明白，请告诉我如何刷新当前目录并在该目录中获取新的ftp文件

推荐答案

我要猜测您正在使用

I''m going to guess that you are using the code from http://www.codeproject.com/KB/dotnet/dotnetftp.aspx[^] if you had of looked through the sample code provided in the article you would have seen that after the Refresh call there is a call back to the function that fills the ListView.

ftpSession.CurrentDirectory.Refresh();
FillListView(); //This calls the code that populates the ListView

最后，如果您对某篇文章中的代码有疑问，通常最好在此发表您的问题.

Lastly if you are having problems with code from an article it is usually best if you post your question there.
