Hi Everyone,

My question relates to a line of PowerShell code that I have come across in a script that automates FTP uploads.

The line in question is:
$request.Method = [System.Net.WebRequestMethods+Ftp]::UploadFile

Instead, I thought that it might have been as follows (but this doesn't work):
$request.Method = [System.Net.WebRequestMethods.Ftp]::UploadFile

Really, I would like someone to explain to me why using the '+' sign instead of '.' means the difference between the overall script working or not.

Thanks so much in advance.

You need this in a .NET developer area really. I suspect there's a better description than I'll come up with here.

The WebRequestMethods class is a container, it contains the FTP class. FTP itself is a sub-class, and to access the sub-class in PowerShell you must use the + notation.

To the first is correct and if you run it as-is you should get STOR back if you run it alone.

Your request is throwing an error?

It is because you're dealing with a nested class. .NET developers would give you a much better answer I'm sure.

But have a look at some of these articles (search for nested ".net nested class plus" on Google and you'll find lots of info on that).
