SortedDictionaryTKey

SortedDictionaryTKey is a generic collection in the .NET framework that stores key-value pairs in a sorted order based on the keys. It is part of the System.Collections.Generic namespace and is implemented as a binary search tree, providing efficient O(log n) time complexity for insertion, deletion, and lookup operations. The keys in a SortedDictionaryTKey must be unique and implement the IComparable interface or a custom comparer can be provided to define the sort order.

The SortedDictionaryTKey class provides a variety of methods for manipulating the collection, including Add, Remove, ContainsKey, and TryGetValue. It also supports enumeration through the Keys and Values properties, allowing for iteration over the keys or values in the collection.

One of the key advantages of SortedDictionaryTKey is its ability to maintain the order of elements based on the keys, which can be useful in scenarios where a sorted collection is required. However, it is important to note that the SortedDictionaryTKey class is not thread-safe, and concurrent access to the collection should be managed appropriately to avoid race conditions.

In summary, SortedDictionaryTKey is a useful data structure for scenarios where a sorted collection of key-value pairs is required, providing efficient operations and maintaining the order of elements based on the keys.
