How to show "no such interface" C# - API?

RouterOS Scripting
1

Hello ,
I want to run a command that wil check me if there is interface in the name of ppp-out2
how can I do it?

I I thought to do something like this :

mikrotik.Send ("/interface/print");
mikrotik.Send ("?name=ppp-out2");
mikrotik.Send ("=proplist=name" , true);

and the answer if there is interface will be :

!re=name=ppp-out2

and if there isn’t such interface I get an empty line

I thought to take the length of the answer
but when there isn’t such interface it doesn’t gice me 0 , it give me empty
so I don’t know how to work with this …


how do I continue from here ?
what to look for?

or is there another way?

Thanks ,
