It is not working because anything written within curly braces String.Format considers it as argument. So you should use double curly braces like {{ or }} so your code become

New Code
 
string.Format("gtag('event', 'conversion', {{'send_to': '{0}/{1}'}});", "aw-xxxx", "xxxx");

Your Previous Code

string.Format("gtag('event', 'conversion', {'send_to': '{0}/{1}'});", "aw-xxxx", "xxxx");

Cheers !
