Hello

I am totally new to this winscp and I have pull the files from the unix box using winscp
I have got below url to refer and code.

https://winscp.net/eng/docs/library_session_listdirectory#example

I have coded accordingly below is my code

Code:
 Try

            ' Setup session options
            Dim mySessionOptions As New SessionOptions
            With mySessionOptions
                .Protocol = Protocol.Sftp
                .HostName = TxtHost.Text
                .UserName = TxtUName.Text
                .Password = TxtPwd.Text
                .PortNumber = 22
                .SshHostKeyFingerprint = TxtKey.Text
            End With

            LblInfo.Text = LblInfo.Text & "Assigned Session Options" & vbNewLine

            Dim mySession As New Session
            Using mySession
                LblInfo.Text = LblInfo.Text & "Session declared " & vbNewLine

                mySession.Open(mySessionOptions)

                LblInfo.Text = LblInfo.Text & "Connected" & vbNewLine

                Dim directory As RemoteDirectoryInfo = mySession.ListDirectory(TxtSource.Text)
                LblInfo.Text = LblInfo.Text & "Setting Transfer Options " & vbNewLine
                Dim fileInfo As RemoteFileInfo
                LblInfo.Text = "-----------------------------------------------------"

                For Each fileInfo In directory.Files
                    'Console.WriteLine("{0} with size {1}, permissions {2} and last modification at {3}", _
                    'fileInfo.Name, fileInfo.Length, fileInfo.FilePermissions, fileInfo.LastWriteTime)

                    LblInfo.Text = LblInfo.Text & fileInfo.Name.ToString & " with size " & fileInfo.Length.ToString & ", permissions " & fileInfo.FilePermissions.ToString & " and last modification at " & fileInfo.LastWriteTime.ToString & vbNewLine

                    'lblinfo.Text = "copied file : " & vbNewLine
                Next
                LblInfo.Text = "-----------------------------------------------------"

            End Using



My SshHostKeyFingerprint is like below format

ssh-rsa 1024 xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx


but when I try to open session I get below error

Host key does not match configured key "
ssh-rsa 1024 xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx"!


Where am I going wrong and someone help me getting it corrected asap

Please attach a full session log file showing the problem (using the latest version of WinSCP).

To generate log file, set Session.SessionLogPath. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you can mark the attachment as private.

You pass "ssh-rsa 1024 03:cc:d2:da:68:06:b7:29:01:fc:b9:1c:4f:c8:2e:ac" to SessionOptions.SshHostKeyFingerprint, but the key is "ssh-rsa 2048 d4:3f:c0:a4:e6:e2:7a:76:48:5a:3e:96:0d:56:c3:a9".
I believe it's pretty self-explanatory.
