.NET Collections and the Large Object Heap (LOH)

Question

Are .NET collections with large number of items apt to be stored in the LOH?

I\'m curious about List and Dictionary specifically. In my code, I store a large number

Answer 1

List is implemented as an array. As such the array will be put into LOH, but the List object itself will not.

The same basically applies to Dictionary as well. It too is using an array of buckets internally, which basically store the key/value pairs you add.
