C# Array Programs

An array is a variable that stores a collection of values of the same type. Array variables are sorted and each variable has an index starting at 0. Memory allocation for arrays in C# is done dynamically. Since arrays are objects, their size can be easily determined using built-in functions. The maximum number of elements that an array may hold is referred to as its length or size. C# array variables can be declared exactly like any other variable by adding [] after the data type.

C# Array Types:

In C# programming, there are three types of arrays:

• Single Dimensional Array
• Multidimensional Array
• Jagged Array

Single Dimensional Array

A single-dimensional array is the simplest type of array in C# that contains only one row to store the values ​​of the same data type. It is also known as a one-dimensional array.

Multidimensional Array

A multidimensional array in C# is an array containing many rows to store data. It is also known as a two-dimensional array.

Jagged Array

A Jagged Array is an array whose elements are arrays. The elements of the jagged array vary in size and dimension.

Advantages of C# Arrays:

• It’s used to give a single name to a collection of data items that are all of the same kind.
• Since C# arrays are strongly typed, the efficiency of the program is improved because there is no boxing and unboxing.
• Easy to traverse, manipulate or sort the data.
• Other data structures, such as linked lists, graphs, trees, stacks, and queues, can be implemented using arrays.

Disadvantages of C# Arrays:

• Fixed array size.
• An element can never be inserted or deleted in the middle of an array.
