How can i log SqlCommand queries to analyze at SQL server tuning advisor

Question

I have a DB connection class which executes all of my DB connections

I want to capture the queries and run them on SQL server tuning advisor to find out missing indexes etc

The SQL server profiler tuning takes forever to process. So i want to compose my own file to analyze

The issue is i don't know how should i capture query to properly analyze

Here my SqlCommand function

SQL server 2014 , c# .net 4.5

My question is what parameters, values etc i should log to analyze them perfectly
