What is the difference between a list and an array in C#?
An array stores a fixed-size sequential collection of elements of the same type, whereas list is a generic collection.
Is list better than array C#?
In general, it’s better to use lists in C# because lists are far more easily sorted, searched through, and manipulated in C# than arrays. That’s because of all of the built-in list functionalities in the language.
What is the difference between a list and an array?
List is used to collect items that usually consist of elements of multiple data types. An array is also a vital component that collects several items of the same data type. List cannot manage arithmetic operations. Array can manage arithmetic operations.
Which one is faster array or list in C#?
In general, one would opt for using Lists (List) due to their flexibility in size. On top of that, msdn documentation claims Lists use an array internally and should perform just as fast (a quick look with Reflector confirms this).
Why is an array better than a list?
Arrays can store data very compactly and are more efficient for storing large amounts of data. Arrays are great for numerical operations; lists cannot directly handle math operations. For example, you can divide each element of an array by the same number with just one line of code.
Should I use a list or array?
Why are lists better than arrays?
The list is better for frequent insertion and deletion, whereas Arrays are much better suited for frequent access of elements scenario. List occupies much more memory as every node defined the List has its own memory set whereas Arrays are memory-efficient data structure.
Why lists are better than arrays?
Because of this, lists are used more often than arrays. Arrays can store data very compactly and are more efficient for storing large amounts of data. Arrays are great for numerical operations; lists cannot directly handle math operations.
Which is more efficient list or array?
An array is faster and that is because ArrayList uses a fixed amount of array. However when you add an element to the ArrayList and it overflows. It creates a new Array and copies every element from the old one to the new one. List over arrays.
In what situation should you use a list instead of an array of T?
Definitely use a List any time you want to add/remove data, since resizing arrays is expensive. If you know the data is fixed length, and you want to micro-optimise for some very specific reason (after benchmarking), then an array may be useful.
Is a list better than an array?
What is IEnumerable in C#?
IEnumerable is an interface defining a single method GetEnumerator() that returns an IEnumerator interface. It is the base interface for all non-generic collections that can be enumerated. This works for read-only access to a collection that implements that IEnumerable can be used with a foreach statement.
Are C# lists 0 indexed?
They are 0 based. Count will start with one however if the list has any items in it. From MSDN if you cared to look it up: Elements in this collection can be accessed using an integer index.
