c# create array

Comment

// Define and Initialize
int[] arr = {1, 2, 3};

// Buuuut:
// Initial defining
int[] arr;

// This works
arr = new int[] {1, 2, 3};   

// This will cause an error
// arr = {1, 2, 3};

arrays in c#

Comment

// There are actually many ways to create an array in C#

// The worst method
int[] array1 = new int[3];
array1[0] = 1;
array1[1] = 2;
array1[2] = 3;

// Declare a single-dimensional array of 5 integers
int[] array1 = new int[5];

// Declare and set array element values
int[] array2 = new int[5] { 1, 2, 3, 4, 5 };

// Alternative syntax
int[] array3 = { 1, 2, 3, 4, 5 };

// Declare a two dimensional array
int[,] multiDimensionalArray1 = new int[2, 3];

// Declare and set array element values
int[,] multiDimensionalArray2 = { { 1, 2, 3 }, { 4, 5, 6 } };

// Declare a jagged array
int[][] jaggedArray = new int[6][];

// Set the values of the first array in the jagged array structure
jaggedArray[0] = new int[4] { 1, 2, 3, 4 };

array declaration in c#

Comment

// Syntax: data_type[] variable_name = new data_type[size];

// Decalring array of integers of length 5
int[] intArr = new int[5];

// Declaring array of strings of length 5
string[] names = new string[5];

// We can also populate the array, if we know the elements in advance
int[] evenDigits = new int[] {0,2,4,6,8}; // notice that in this, we don't need explicit size declaration.

The first example creates an array of integers with five elements, while the second example creates an array of strings with three initial elements. The third example creates a two-dimensional array with two rows and two columns.

// create an array of integers
int[] numbers = new int[5];

// create an array of strings with initial values
string[] names = new string[] {"John", "Jane", "Bob"};

// create a multidimensional array
int[,] matrix = new int[2,2];

c# make array

Comment

Use the var keyword to create an array without specifying its type explicitly:

// create an array of integers
var numbers = new int[] {1, 2, 3, 4, 5};

This will create an array of integers with five elements and assign it to the numbers variable.
