In C# programming, there are two ways of storing a collection of strings:
List<string>. both of them can be used to store a collection of strings, but they have some key differences that can affect how you use them.
string is an array of strings. It has a fixed size, which means that the number of elements in the array is determined at the time the array is created, and cannot be changed afterwards. You can access individual elements of the array using an index, like
myArray. Arrays can be useful when you know exactly how many elements you need to store, and you don’t need to add or remove elements dynamically.
List<string> is a generic collection that can grow or shrink dynamically. It is based on the
List<T> class in C#, which provides methods for adding, removing, and manipulating elements in the list. You can access individual elements of the list using an index, like
myList. Lists can be useful when you need to store a variable number of elements, or when you need to add or remove elements from the collection dynamically.
Here is an example to demonstrate the difference:
In general, if you need to add or remove elements from a collection dynamically, or if you don’t know how many elements you will need to store, you should use
List<string>. If you know exactly how many elements you need to store and you don’t need to add or remove elements dynamically, you can use
string. Happy coding!
