What is SortedDictionary?
In C#, SortedDictionary is a generic collection which is used to store the key/value pairs in the sorted form and the sorting is done on the key. SortedDictionary is defined under System. Generic namespace. It is dynamic in nature means the size of the sorted dictionary is growing according to the need.
How is SortedDictionary implemented?
SortedDictionary is implemented with Binary Search Tree, while SortedList is implemented with two internal arrays for keys and values, respectively. SortedList is more memory-efficient than SortedDictionary, and SortedList is faster than SortedDictionary when it needs to go through all items at once.
When should I use SortedList?
On unsorted data the SortedList is slightly quicker on retrieval, but about 9 times slower on adding….To roughly summarize, you want a SortedList when:
- you require indexed look-up.
- it’s desirable to have lesser memory overhead.
- your input data is already sorted (say you get it already ordered from db).
Is Dictionary in C# sorted?

What is ordered dictionary in C#?
OrderedDictionary Class represents a collection of key/value pairs that are accessible by the key or index. It is present in System.
Where an array is sorted in memory?
A sorted array is an array data structure in which each element is sorted in numerical, alphabetical, or some other order, and placed at equally spaced addresses in computer memory. It is typically used in computer science to implement static lookup tables to hold multiple values which have the same data type.
In what way SortedList will add the values?
The Add() method is used to add a single key-value pair in a SortedList . Keys cannot be null or duplicate. If found, it will throw a run-time exception. Values can be duplicate and null if the type is nullable.
What is SortedList in Python?
SortedList – Sorted list is a sorted mutable sequence in which the values are maintained in sorted order. Functions to add and remove elements: add(value) : A function that takes one element as parameter and inserts it into the list by maintaining sorted order. Runtime Complexity: O(log(n))
