void (C# reference)

You use void as the return type of a method (or a local function) to specify that the method doesn't return a value.

public static void Display(IEnumerable<int> numbers)
{
    if (numbers is null)
    {
        return;
    }
    
    Console.WriteLine(string.Join(" ", numbers));
}

You can also use void as a referent type to declare a pointer to an unknown type. For more information, see Pointer types.

You cannot use void as the type of a variable.
