It holds a key: value pair in which we can easily access a value if the key is known. It improves the readability of your code and makes it easier to debug It is fast as the access of a value through a key is a constant time operation Dictionary representation: C++ Java Python C# JavaScriptSat, 04 Apr 2026 17:10:00 GMThttps://learn.microsoft.com/en-us/dotnet/csharp/language-reference/builtin-types/arraysYou can store multiple variables of the same type in an array data structure. You declare an array by specifying the type of its elements. If you want the array to store elements of any type, specify object as its type. In the unified type system of C#, all types, predefined and user-defined, reference types and value types, inherit directly or indirectly from Object. The C# language reference ...Sun, 05 Apr 2026 13:20:00 GMThttps://www.geeksforgeeks.org/c-sharp/dictionary-in-c-sharp/Dictionary in C# is a generic collection that stores key-value pairs. The working of Dictionary is quite similar to the non-generic hashtable. The advantage of a Dictionary is, that it is a generic type. A dictionary is defined under System.Collections.Generic namespace.Sat, 04 Apr 2026 17:18:00 GMThttps://stackoverflow.com/questions/2695024/array-list-vs-dictionary-why-we-have-them-at-first-placeThe example which you have given can be implemented by by n*2 array? infect to me dictionary is n*2 array. My interpretation is right? You are correct in the first part; An N*2 or 2-dimensional array is another way of storing key-value pairs. On the outside, a dictionary and a n*2 array do the same things.Sun, 29 Mar 2026 17:39:00 GMThttps://www.geeksforgeeks.org/c-sharp/c-sharp-array-vs-arraylist/Your All-in-One Learning Portal: GeeksforGeeks is a comprehensive educational platform that empowers learners across domains-spanning computer science and programming, school education, upskilling, commerce, software tools, competitive exams, and more.Sat, 04 Apr 2026 23:16:00 GMThttps://learn.microsoft.com/en-us/dotnet/csharp/language-reference/builtin-types/collectionsLearn about collections in C#, which are used to work with groups of objects. Collections have different characteristics regarding adding and removing elements, modifying elements, and enumerating the collection elements.Sat, 04 Apr 2026 22:11:00 GMThttps://stackoverflow.com/questions/8307222/dictionary-list-or-arrayThe list of pairs approach is the slowest, since you might have to traverse the whole list to find your entry, which yields O (n) complexity. Thus, in your situation, I would choose the dictionary, unless the marginally better performance of the huge array is really relevant in your case.Fri, 27 Mar 2026 18:03:00 GMThttps://learn.microsoft.com/en-us/dotnet/standard/collections/hashtable-and-dictionary-collection-typesA Dictionary<TKey,TValue> of a specific type (other than Object) provides better performance than a Hashtable for value types. This is because the elements of Hashtable are of type Object; therefore, boxing and unboxing typically occur when you store or retrieve a value type.Sat, 04 Apr 2026 07:09:00 GMThttps://stackoverflow.com/questions/2448974/c-sharp-array-or-dictionaryAn array access in C# is a simple index operation, whereas a dictionary is a hash table lookup. Arrays are comparable to C++ arrays except for some small overhead of bounds-checking performed by the language.Fri, 03 Apr 2026 12:18:00 GMThttps://stackoverflow.com/questions/434761/array-versus-listt-when-to-use-whichA List uses an internal array to handle its data, and automatically resizes the array when adding more elements to the List than its current capacity, which makes it more easy to use than an array, where you need to know the capacity beforehand.Sun, 05 Apr 2026 04:23:00 GMT
