What is difference between these two array declarations?

Question

It seems these two declarations are the same:

int[] array1 = {11, 22, 33};

and

int[] array2 = new int[] {11, 22, 33};
         


        

Answer 1

int[] array1; // declare array1 as an int array of any size
array1 = new int[10];  // array1 is a 10-element array
array1 = new int[20];  // now it's a 20-element array

int[] array2 = new int[5] {1, 2, 3, 4, 5}; // declare array 2 as an int array of size 5

Both are the same. See here at MSDN on initializing arrays.
