CODE EXAMPLE FOR CSHARP

how to write int array to console c#

You may try this:

foreach(var item in yourArray)
{
  Console.WriteLine(item.ToString());
}
Also you may want to try something like this:
yourArray.ToList().ForEach(i => Console.WriteLine(i.ToString()));

EDIT: to get output in one line [based on your comment]: 

Console.WriteLine("[{0}]", string.Join(", ", yourArray));
//output style:  [8, 1, 8, 8, 4, 8, 6, 8, 8, 8]

EDIT(2019): As it is mentioned in other answers it is better to use Array.
ForEach<T> method and there is no need to do the ToList step.

Array.ForEach(yourArray, Console.WriteLine);
