c# make an array of values that can be a certain type code example

Example 1: 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};

Example 2: c# array

float[] array = new float[] { 1f, 5f, 4f, 3f };
