Hi,

I was trying to get the latest file from FTP server using the ftp.GetFileDateTime function but I am getting below error. Error: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> Rebex.Net.FtpException: command MDTM is not available for DAT.G(550). Can anyone help me to get this fix. I want to get the latest file from available files. Thanks for your help!

Regards, Abhiyanta

It looks like you encountered one of the FTP server that don't support the MDTM command (used to retrieve a date/time of a single file by GetFileDateTime method. This command was not originally a part of FTP protocol, and some servers have never added support for it.

As a workaround, you would have to use the GetList method to retrieve a list of all files in a directory. Then, find the latest file in the list - the returned list is a list of FtpItem objects with LastWriteTime property set.
