how to declare an array csharp code example

Example 1: c# initialize array

string[] stringArray = new string[6];
//or
int[] array1 = new int[] { 1, 3, 5, 7, 9 };
//
string[] weekDays = new string[] { "Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat" };
//etc

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};
