I couldnt bind Image source

Here is binding:

<Image Width="16" Height="16"  Source="{Binding SwitchForImage, Converter={StaticResource stringToImage}}" HorizontalAlignment="Left">
</Image>

and here is the Convertor

public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        string type = (string)value;
        BitmapImage logo = new BitmapImage();
        logo.BeginInit();
        logo.UriSource = new Uri(@"pack://application:,,,/Resources/"+type+@"Icon.png");
        logo.EndInit();
        return logo;
    }

when i run ,gives this exception "Cannot locate resource 'resources/*icon.png' ".But i put png files into folder named Resources.I am creating library.These all in library.For test i used it,and then occured this problem.

I added png files as"include to project".Build action is "Content".But i tried others also(Resource,Embedded resource)

[Answer] I changed Build Action to Resource and changed Convert like that:

public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        return "/AutoComplete;component/Resources/" + (string)value + "Icon.png";
    }

And everything work normally.

I changed Build Action to Resource and changed Convert method like that:

public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
    return "/AutoComplete;component/Resources/" + (string)value + "Icon.png";
}
