How do I fix an array error?

Hi,
I have have a string array:

C#

public class Example
{
    public string[] Layers = new string[] { };

    public Example()
    {
        //Just to be safe...
        this.Layers = new string[] { };
    }
}

and whenever I try to access a member of that string array:

C#

Example test = new Example();
test.Layers[Convert.ToInt32(numericUpDown1.Value)] = textbox1.Text;

it always gives me an IndexOutOfRange exception. Why is this happening and how can I fix it? Because logically it should work?.. and also can someone please answer at where an array starts? Is it 1 or 0?

Thanks Jake

You need to mention the size of the array

C#

public class Example
   {
       public string[] Layers = new string[7] ;

       public Example()
       {
           //Just to be safe...
           this.Layers = new string[7] ;
       }
   }

Morevover Array index starts from 0 in C#

Have a look at this

Solution 2

According to you code there are no members (it's a zero length array).
You need something like this:

C#

this.Layers = new string[] { "a", "b", "c" };
