Does anyone know of any google api youtube v3 code sample which works with unity?

i have found a few samples here https://developers.google.com/youtube/v3/code_samples/dotnet however, they are confusing for me to integerate into unity, for starters i get the error of referenced script "name" behavour is missing, because in the samples there isnt any reference to the script class however i dont know how i would add it in the sample, can anyone help make the "search by keyword" sample code in the website work?
