Good explanation sir. In short IEnumerable featch the data and filtere it rather than IQuerable featch filtered data. That's why it is faster as compare to IEnumerable

Nice video, one point IQueryable executes a "select query" on server-side with all filters that appended to it until database execution. That give to use make more flexible code.

Hi Sir, I have one doubt.. in which scenario we have to use innumerable rather than iqurable in linq query ?

@interviewhappy Год назад

When you have in-memory collections

@@interviewhappyyesterday i was testing IEnumerable and IQueryable and got the same result using inline query with linq Where(),that is each of them generated sql where.But using 2 lines,like : IEnumerable data = context.Users; var filtered = data.Where(...).ToList(); In this case with IEnumerable we don't have sql where.Can you clarify it?
