 DateTime dateTime = DateTime.Parse(date);

Actually this error is shown in my home pc where i am using window xp and visual 2010........... .........howeve r in my university lab on window 7 it works fine by passing second parameter as System.Globaliz ation.culturein fo.createspecif icculture("en-US").DateTimeFo rmat.Like:

DateTime dateTime = DateTime.Parse(date, System.Globalization.CultureInfo.CreateSpecificCulture("en-US").DateTimeFormat);

Please anyone help me regarding this exception.:(

Hope you understand my question.

for this:

DateTime dateTime = DateTime.Parse(date);

where do you get the value of this variable "date" in the above statement?
Where does the value come from?

Dear Adriancs,

Please see the below mentioned code actually it is a function which will recursively get the list of files from FTP server.

 
struct DirectoryItem
    {
        public Uri BaseUri;
 
        public string AbsolutePath
        {
            get
            {
                return string.Format("{0}/{1}", BaseUri, Name);
            }
        }  
        public DateTime DateCreated;
        public bool IsDirectory;
        public string Name;
        public List<DirectoryItem> Items;
    }

public List<DirectoryItem> GetDirectoryInformation(string address, string username, string password)
        {
            FtpWebRequest request = (FtpWebRequest)FtpWebRequest.Create(address);
            request.Method = WebRequestMethods.Ftp.ListDirectoryDetails;
            request.Credentials = new NetworkCredential(username, password);
            request.UsePassive = true;
            request.UseBinary = true;
            request.KeepAlive = false;

            List<DirectoryItem> returnValue = new List<DirectoryItem>();
            string[] list = null;

            using (FtpWebResponse response = (FtpWebResponse)request.GetResponse())
            using (StreamReader reader = new StreamReader(response.GetResponseStream()))
            {
                list = reader.ReadToEnd().Split(new string[] { "\r\n" }, StringSplitOptions.RemoveEmptyEntries);
            }

            foreach (string line in list)
            {
                // Windows FTP Server Response Format
                // DateCreated    IsDirectory    Name
                string data = line;

                // Parse date
                string date = data.Substring(0,17);
                DateTime dateTime = DateTime.Parse(date);

                data = data.Remove(0, 24);

                // Parse <DIR>
                string dir = data.Substring(0, 5);
                bool isDirectory = dir.Equals("<dir>", StringComparison.InvariantCultureIgnoreCase);
                data = data.Remove(0, 5);
                data = data.Remove(0, 10);

                // Parse name
                string name = data;

                // Create directory info
                DirectoryItem item = new DirectoryItem();
                item.BaseUri = new Uri(address);
                item.DateCreated = dateTime;
                item.IsDirectory = isDirectory;
                item.Name = name;


                // Debug.WriteLine(item.AbsolutePath);

                item.Items = item.IsDirectory ? GetDirectoryInformation(item.AbsolutePath, username, password) : null;

                f.listboxFiles.Items.Add(name);

                returnValue.Add(item);
            }

            return returnValue;
        }

And call to this function is

List<DirectoryItem> listing = GetDirectoryInformation(ftptxtbox.Text, "anonymous", "anonymous");

you can create your own string to DateTime converter. Create a function like this:

public static DateTime GetDateTime(string date)
{
    // assume that
    // date = "2012-02-21 21:29:30";
    int year = Convert.ToInt32(data.Substring(0, 4));
    int month = Convert.ToInt32(data.Substring(5, 2));
    int day = Convert.ToInt32(data.Substring(8, 2));
    int hour = Convert.ToInt32(data.Substring(11, 2));
    int minute = Convert.ToInt32(data.Substring(14, 2));
    int second = Convert.ToInt32(data.Substring(17, 2));
    return new DateTime(year, month, day, hour, minute, second);
}

or

public static DateTime GetDateTime(string date)
{
    // assume that
    // date = "2012-02-21-21-34-30";
    string[] sa = data.Split('-');
    int[] ia = new int[sa.Length];
    for (int i = 0; i < sa.Length; i++)
    {
        ia[i] = Convert.ToInt32(sa[i]);
    }
    return  new DateTime(ia[0], ia[1], ia[2], ia[3], ia[4], ia[5]);
}

or

public static DateTime GetDateTime(string date)
{
    // assume
    // date = "21 Feb 2012, 09:42 PM";
    string[] sa = date.Split(',');
    string[] separator1 = new string[] { " " };
    string[] sb = sa[0].Trim().Split(separator1, StringSplitOptions.None);

    int day = Convert.ToInt32(sb[0]);

    int month = 0;

    switch (sb[1].ToUpper())
    {
        case "JAN":
            month = 1;
            break;
        case "FEB":
            month = 2;
            break;
        
        .....

        default:
            break;
    }

    int year = Convert.ToInt32(sb[2]);

    string[] sc = sa[1].Split(':');

    int hour = Convert.ToInt32(sc[0]);

    string[] sd = sc[1].Split(separator1, StringSplitOptions.None);

    int minute = Convert.ToInt32(sd[0]);

    if (sd[1].ToUpper() == "PM")
        hour += 12;

    return new DateTime(year, month, day, hour, minute, 0);
}

then,

DateTime dateTime = GetDateTime(date);
