issues with Arrays in C#

Question

Console.WriteLine("Please enter your number of the Names : ?");
int x = Convert.ToInt32(Console.ReadLine());
string[] names = new string[x];
for (int i = 0; i < x; i++)
{
    Console.Write("Enter Name no.{0} :  ", i + 1);
    names[i] = Console.ReadLine();
}

Console.WriteLine("the items are {0}", names);
Console.ReadKey();

Now when I want to type down the names, it just prints the first Name entered!

Like if I have 5 names, in the last line in the

Console.WriteLine("the items are {0}", names);

it just prints out the 1st name!

Answer 1

You'll want to do a loop at the end as well

Either a for loop or a foreach , the current way you are using Console.WriteLine() is using the string.Format() overload

foreach (string name in names)
{
    // Write out here
    Console.WriteLine(name);
}

Answer 2

Join the strings together with the separator you want, before passing them to writeline.

Use string.Join to do so.

Passing an array to WriteLine makes out think you are passing an array with values to format.

Answer 3

You have to do a loop.

Console.Write("the items are");
for (int i = 0; i < names.Length; ++i)
{
    Console.Write(" ");
    Console.Write(names[i]);
}
Console.WriteLine();

Answer 4

//Console.WriteLine("the items are {0}.", String.Join(", ", names));
string argsFormat = ( 1 < x) ?
    String.Join(", ", Enumerable.Range(0, x).Select(n => "{" + n + "}").ToArray())
    .Replace(", {" + (x-1) + "}", " and {" + (x-1) + "}") + "." 
    :
    argsFormat = "{0}.";
Console.WriteLine("the items are " + argsFormat , names);
