I have a mongo collection where i have field called links, this link has value like this

“/company/11761390”

Now in my code i have a comapny number that i need to match with this value after / one only.
To achieve this i Have written below code but that does not work

newAppointmentList.items.Where(a => a.links.company.Split('/')[2] == company_number).FirstOrDefault() 

I have also tried the other way

newAppointmentList.items.Where(a => a.links.company.contains(company_number)).FirstOrDefault()

both not working.
