Get file or folder info using FTP
Server responses to FTP protocol’s LIST command are not well standardized. Ftp.dll FTP .NET component was programmed to handle almost any format of such response. This includes UNIX, Linux and Windows systems. Additionally if a server supports better standardized MLSD command, it is used instead of LIST.
To list all files and folders in current folder just use GetList method of Ftp class.
You’ll receive FtpItem collection you can easy iterate over. You can access each item’s information like: name, size, modification date by using FtpItem‘s properties.
// C# version
using (Ftp client = new Ftp())
{
client.Connect("ftp.example.org"); // or ConnectSSL for SSL
client.Login("user", "password");
List<FtpItem> items = client.GetList();
foreach (FtpItem item in items)
{
Console.WriteLine("Name: {0}", item.Name);
Console.WriteLine("Size: {0}", item.Size);
Console.WriteLine("Modify date: {0}", item.ModifyDate);
Console.WriteLine("Is folder: {0}", item.IsFolder);
Console.WriteLine("Is file: {0}", item.IsFile);
Console.WriteLine("Is symlink: {0}", item.IsSymlink);
Console.WriteLine();
}
client.Close();
}
' VB.NET version
Using client As New Ftp()
client.Connect("ftp.example.org") ' or ConnectSSL for SSL
client.Login("user", "password")
Dim items As List(Of FtpItem) = client.GetList()
For Each item As FtpItem In items
Console.WriteLine("Name: {0}", item.Name)
Console.WriteLine("Size: {0}", item.Size)
Console.WriteLine("Modify date: {0}", item.ModifyDate)
Console.WriteLine("Is folder: {0}", item.IsFolder)
Console.WriteLine("Is file: {0}", item.IsFile)
Console.WriteLine("Is symlink: {0}", item.IsSymlink)
Console.WriteLine()
Next
client.Close()
End Using
Getting basic file information using FTP
Follow code illustrates how to get basic information about specific file, such as size and last modification date, using FTP protocol:
// C# version
using (Ftp client = new Ftp())
{
client.Connect("ftp.example.org");
client.Login("user", "password");
long size = client.GetFileSize("reports/report_2010.txt");
DateTime date = client.GetFileModificationTime("reports/report_2010.txt");
Console.WriteLine("Size: {0}", size);
Console.WriteLine("Modify date: {0}", date);
client.Close();
}
' VB.NET version
Using client As New Ftp()
client.Connect("ftp.example.org")
client.Login("user", "password")
Dim size As Long = client.GetFileSize("reports/report_2010.txt")
Dim [date] As DateTime = client.GetFileModificationTime("reports/report_2010.txt")
Console.WriteLine("Size: {0}", size)
Console.WriteLine("Modify date: {0}", [date])
client.Close()
End Using
