//You could just do it like this to make it more dynamic: (set the loop condition based on the actual length of the array)

int[] a = {1, 2, 3};
for(int i =0; i < a.Length; i++);
Console.WriteLine(a);

Answer 1

Console.Writeline(object) calls Tostring method for any object to produce its string representation.
'a' is massive, it is a reference type(object). By default Object.ToString return fully name of the object's type if it is not overrided. For array it is not overrided.

Answer 2

I guess you want to display all array values. But your code contains syntax mistake. You code has a extra comma at the end of for loop. Remove it and add index of showings element of array a[i]
