[Edit] - Needless to say - it's not "either this or that". often it would make good sense to use both a list and an IEnumerable in the same class. No computer in the world could list all prime numbers, because by definition this would require an infinite amount of memory. But you could easily think of a class PrimeContainer which contains an IEnumerable primes, which for obvious reasons also contains a SortedList _primes.
are two properties in particular—one that points to a query provider (e.g., a LINQ to SQL provider) and another one pointing to a query expression representing the IQueryable object birli a runtime-traversable abstract syntax tree that birey be understood by the given query provider (for the most part, you sevimli't give a LINQ to SQL expression to a LINQ to Entities provider without an exception being thrown).

It is cleaner, your users don't get a list where they shouldn't (they could cast it to a Listafter all) and you don't need to create a Listobject.
IEnumerable enable implicit reference conversion for array types which known kakım Covariance. Consider the following example:
In simple words other major difference is that IEnumerable execute select query on server side, load veri in-memory on client side and then filter data while IQueryable execute select query on server side with all filters.
