C# Array Contents not showing, but type is

Question

public partial class Form1 : Form
{
    private string[] myArray = { "Eddie", "Amber", "Kelly" };

    public void showMe()
    {
        foreach (string i in myArray) 
            MessageBox.Show(myArray.ToString()); 

    }

    private void button1_Click(object sender, EventArgs e) => showMe();
}

Hi everybody,

I'm trying to get the names from myArray to be shown in the MessageBox, but all I'm getting is a MessageBox with System.String[] and I'm not sure why? Can someone please tell me what I'm doing wrong?

Thanks

Eddie

Answer 1

That's the default behaviour of ToString(). It just prints the type name of the object, unless defined otherwise for a specific type.

You want to use

foreach (string i in myArray)
    MessageBox.Show(i);

to display a separate messagebox for each element in the array or

MessageBox.Show(string.Join(",", myArray));

to display a single messagebox with all elements of the array.
