Handle errors

Exceptions thrown by the component and its dependencies can easily be caught by using try catch block. The table below lists all exceptions that can be caught when using the component: 

The example below shows how to handle exceptions:

using System;
using ComponentPro.IO;
using ComponentPro.Net;

...

// Create a new class instance.
Sftp client = new Sftp();

try
{
    // Connect to the SFTP server. 
    client.Connect("myserver");

    // Authenticate. 
    client.Authenticate("userName", "password");

    // ... 
 
    // Create 'myFolder' folder. 
    client.CreateDirectory("/myFolder");

    // ... 
 
    // Disconnect. 
    client.Disconnect();
}
catch (SftpException exc)
{
    if (client.State == RemoteFileSystemState.Connected ||
        client.State == RemoteFileSystemState.Ready)
    {
        client.Disconnect();
    }

    Console.WriteLine("An error occurred: " + exc.Message);
}

Imports ComponentPro.IO
Imports ComponentPro.Net

...

' Create a new class instance. 
Dim client As New Sftp()

Try 
    ' Connect to the SFTP server. 
    client.Connect("myserver")

    ' Authenticate. 
    client.Authenticate("userName", "password")

    ' ... 
 
    ' Create 'myFolder' folder. 
    client.CreateDirectory("/myFolder")

    ' ... 
 
    ' Disconnect. 
    client.Disconnect()
Catch exc As SftpException
    If client.State = RemoteFileSystemState.Connected OrElse client.State = RemoteFileSystemState.Ready Then 
        client.Disconnect()
    End If 
 
    Console.WriteLine("An error occurred: " & exc.Message)
End Try
