declare int array in c# code example

Example 1: c# create array of int

int[] array = new int[]; // []
int[] array = new int[5]; // [0, 0, 0, 0, 0]
int[] array1 = new int[] { 1, 3, 5, 7, 9 };

Example 2: c# create array

// 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};
