Introduction to Arrays in C#
Array
In C#, an array is a data structure that stores a fixed-size sequence of elements of the same type. Arrays are widely used in programming for tasks that involve working with collections of data, such as storing a list of numbers, strings, or objects.
Example : int[] numbers = new int[5];
Describe:
- An array always stores values of a single data type
Example:
int[] numbers = {2,4,5,7}; //allow single data type
int[] numbers = {2,4,5,"Amit" }; //compile error, convert type string to int
- C# supports zero-based index values in an array
Example:
int[] numbers = { 1, 2, 3, 4, 5 };
- Arrays have a fixed length, means that once your create an array with a specific size, you cannot change its size later, The size of an array is determined at the time of its declaration.
int[] myarray = new int[4];
myarray[0] = 1;
myarray[1] = 2;
myarray[2] = 3;
myarray[3] = 4;
