Upload file using FTP

First you need to add reference to Ftp.dll .NET FTP library, and import appropriate namespaces:

// C# version

using Limilabs.FTP.Client;

' VB.NET version

Imports Limilabs.FTP.Client

The following code uploads the file from disk to reports folder on the server, using FTP protocol:

// C# version

using (Ftp client = new Ftp())
{
    client.Connect("ftp.example.com");    // or ConnectSSL for SSL
    client.Login("user", "password");

    client.Upload(@"reports\report.txt", @"c:\report.txt");

    client.Close();
}

' VB.NET version

Using client As New Ftp()
	client.Connect("ftp.example.com")    ' or ConnectSSL for SSL
	client.Login("user", "password")

	client.Upload("reports\report.txt", "c:\report.txt")

	client.Close()
End Using

You can also upload the file from memory:

// C# version

using (Ftp client = new Ftp())
{
    client.Connect("ftp.example.com");    // or ConnectSSL for SSL
    client.Login("user", "password");

    byte[] bytes = Encoding.Default.GetBytes("Hello from Ftp.dll");
    client.Upload(@"reports\report.txt", bytes);

    client.Close();
}

' VB.NET version

Using client As New Ftp()
	client.Connect("ftp.example.com")    ' or ConnectSSL for SSL
	client.Login("user", "password")

	Dim bytes As Byte() = Encoding.[Default].GetBytes("Hello from Ftp.dll")
	client.Upload("reportsreport.txt", bytes)

	client.Close()
End Using

Finally you can also use overload that uses any Stream as the source.
