        protected override void OnNavigatedTo(NavigationEventArgs e)
        {
            DateTime dt = DateTime.Now;
            int month = dt.Month;
            int year = dt.Year;
            int index;

            if (DateTime.IsLeapYear(year) || (month <= 2))
            {
                index = dt.DayOfYear - 1; // list is indexed from 0
            }
            else
            {
                index = dt.DayOfYear; // add a day
            }

            textblock.Text = devotions[index].ToString(); // or some other property
        }

        private void AddDevotions()
        {
            for (int i = 1; i <= 366; i++)
            {
                string filePath = "BibleInYear/Bible" + i.ToString() + ".json";
                BibleData d = ReadJsonFile(filePath);
                devotions.Add(d);
            }
        }

        public BibleData ReadJsonFile(string JsonfilePath)
        {
            BibleData[] d = null;

            using (StreamReader r = new StreamReader(JsonfilePath))
            {
                string json = r.ReadToEnd();
                d = JsonConvert.DeserializeObject(json);
            }
            return d[0];
        }

Thank you in advance and reply soon

Hi,
Jhon,

SteamReader can't the read the DLL type of file.
You can disassemble .NET Assembly (forget DLLs and EXEs — for .NET this is practically the same; well, EXE has an entry point, usually Main and DLL may or may not have one; that's it; EXE can be referenced as a library exactly as DLL, there are cases when it's even practical to do so).

See MSIL disassembler (Ildasm.exe), http://msdn.microsoft.com/en-us/library/f7dy01k1%28v=VS.100%29.aspx

When you disassemble the assembly in IL code, you can modify it and assemble again using MSIL assembler (Ilasm.exe), see http://msdn.microsoft.com/en-us/library/496e4ekx%28v=VS.100%29.aspx

Reflector is a powerful tool, but you can have another tool free of charge: Open Source ILSpy, http://wiki.sharpdevelop.net/ilspy.ashx

It's not too difficult to "reflect" DLL using System.Reflection, but to disassemble if in full… much, much harder.

Hi Vulpes

When i rewrite my code i got this error "An exception of type 'System.NullReferenceException' occurred in DevotionText.DLL but was not handled in user code"

The code below

// xaml.cs
public partial class MainPage : PhoneApplicationPage
    {
        List devotions = new List();

        // Constructor
        public MainPage()
        {
            InitializeComponent();

            AddDevotions();

            // Sample code to localize the ApplicationBar
            //BuildLocalizedApplicationBar();
        }

        protected override void OnNavigatedTo(NavigationEventArgs e)
        {
            DateTime dt = DateTime.Now;
            int month = dt.Month;
            int year = dt.Year;
            int index;

            if (DateTime.IsLeapYear(year) || (month <= 2))
            {
                index = dt.DayOfYear - 1; // list is indexed from 0
            }
            else
            {
                index = dt.DayOfYear; // add a day
            }

            textblock.Text = devotions[index].ToString(); // or some other property
        }

        private void AddDevotions()
        {
            for (int i = 1; i <= 366; i++)
            {
                string filePath = "Devotions/Devotion1" + i.ToString() + ".txt";

                devotions.Add(d);
            }
        }

        public string ReadTextFile(string textFilePath)
        {
            string text = null;

            using (StreamReader r = new StreamReader(textFilePath))
            {
                text = r.ReadToEnd();
            }

            return text;
        }

        public string d { get; set; }

Kindly help

If that code works for JSON files, then this code should work for ordinary text files:

public string ReadTextFile(string textFilePath)
{
string text = null;

using (StreamReader r = new StreamReader(textFilePath))
{
text = r.ReadToEnd();
}

return text;
}
