Question

my Window has an array of double as a field :

double[] sizes = new double[] {1.0, 2.0, 3.0, 4.0};

and also a combo box which I want it to have exact Items as the array above.
can anyone help me with xaml binding this array as a resource for the combo box?

I don’t know what your code looks like but here’s an example of how to bind an array to a ComboBox

<Window x:Class="WpfApplication1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
<Grid>
    <ComboBox ItemsSource="{Binding Sizes}" />
</Grid>
</Window>

Code behind:

namespace WpfApplication1
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public double[] sizes = new double[] { 1.0, 2.0, 3.0, 4.0 };
        public double[] Sizes
        {
            get { return sizes; }
        }

        public MainWindow()
        {
            this.DataContext = this;   
        }
    }
}
