What is the analogous class of C++ std::vector in C#?
I want a class where it keeps an internal array inside and supports insertion at the back in O(1) time.

There is no C standard equivalent to the c++ vector, though you could create a struct based off of the vector in c++. The struct would. Resize itself if the array bounds are passed the max size. perform the operations similar to that of a vector.
Difference between std::vector and std::array in C++Vector is a sequential container to store elements and not index based. Array stores a fixed-size sequential collection of elements of the same type and it is index based. Vector is dynamic in nature so, size increases with insertion of elements.
Program to create Custom Vector Class in C++ int push_back(data): adds an element(of any data_type) to the end of array and also returns the number of elements in that vector. data_type pop_back(): removes an element from the end of array, also returns the popped element.
Vectors are a modern programming concept, which, unfortunately, aren't built into the standard C library. Vectors are same as dynamic arrays with the ability to resize itself automatically when an element is inserted or deleted, with their storage being handled automatically by the container.
Here is a list with some C++ / C# containers that are roughly equivalent (not exact replacements) to each other:
std::vector -> List<T>
std::list -> LinkedList<T>
std::map -> SortedDictionary<Tkey, Tvalue>
std::set -> SortedSet<T>
std::unordered_set -> HashSet<T>
std::multiset -> SortedDictionary<Tkey, int> (int keeping count of the number of Tkeys)
std::unordered_map -> Dictionary<TKey, TValue>
