Head To Head Comparison Between C# List and Array (Infographics)An array stores a fixed-size sequential collection of elements of the same type. It is used to store a data collection, but the array can be considered a collection of variables of the same type stored at contiguous memory locations. All arrays consist of contiguous memory locations, with the lowest address corresponds to the first element and the highest address to the last element. Below are the top 8 differences between C#List vs Array Key Differences between C# List and ArrayBoth are popular choices in the market; let us discuss some of the major differences:

ConclusionBoth C# List vs Array are distinct types, having different capabilities and store their data in separate ways. The storing capabilities and design of both data structures make them unique in their own ways. An Array is fixed in size, and once it is allocated, one cannot add or remove items from it; also, all elements must be of the same type. Thus, it is a type-safe and most efficient linear data structure in terms of speed and performance. Also, Array supports multiple dimensions. The list provides more generic capabilities and derived from Collection APIs. Unlike Array, they are dynamic in nature, can resize automatically with frequent insertion and deletion of elements. It is essentially a type-safe version of an ArrayList data structure. Type safety feature means there is no boxing or unboxing, which would enhance performance, and if anyone attempts to add an element of the wrong type, it will generate a compile-time error. C# List vs Array performance is a linear data structure that is well suited for different scenarios. If frequent insertion and deletion occur, and at the same time, memory is not a constraint, then List is an ideal choice, whereas in scenarios like frequent access of elements of required with a memory constraint, then Array is a better option. It all depends upon the use case and requirement. An array is always a list in nature, but a list is not an array. The array allows both kinds of access, direct and sequential, while List only allows sequential access. And this is because of the way these data structures are stored in memory. Since List is derived from Collection, it can use different implementations; one of these implementations is ArrayList, a class that implements the Lists behaviour using arrays as a data structure. An Array is very much tied to the hardware notion of continuous, contiguous memory, with each element identical in size. Both performance ideas line up quite well, based on scenarios. It all boils down to the requirement at the end of the day, although the memory part can be safely side-line in todays world since high memory has become a norm.
