Is there a limit of elements that could be stored in a List ? or you can just keeping adding elements untill you are out of memory ?
What is the use of default keyword in C#? Is it introduced in C# 3.0 ?

The current implementation of List<T>
uses Int32
everywhere - to construct its backing array, for its Count
property, as an indexer and for all its internal operations - so there s a current theoretical maximum of Int32.MaxValue
items (2^31-1
or 2147483647
).
But the .NET framework also has a maximum object size limit of 2GB, so you ll only get anywhere near the items limit with lists of single-byte items such as List<byte>
or List<bool>
.
In practice you ll probably run out of contiguous memory before you hit either of those limits.
