An XML document contains error (0,0)

I have XML document:

<?xml version="1.0" encoding="utf-8" ?>
<Menu>
  <MainMenu>
    <Meal>Example1</Meal>
    <Meal>Example1</Meal>
    <Meal>Example1</Meal>
    <Meal>Example1</Meal>
    <Meal>Example1</Meal>
    <Meal>Example1</Meal>
  </MainMenu>
</Menu>

And I whant to deserialize it as list in class MainMenu:

   [Serializable()]
    public class MainMenu
    {
        [System.Xml.Serialization.XmlElementAttribute("Meal")]
        private List<string> Meal;

        public MainMenu()
        {
            Meal = new List<string>();
        }
    }

By method: 

private void MenuDeserializer()
{
    MainMenu mainMenu = null;
    string path = "MenuXML.xml";

    XmlSerializer serializer = new XmlSerializer(typeof(MainMenu));

    StreamReader reader = new StreamReader(path);
    reader.ReadToEnd();
    mainMenu = (MainMenu)serializer.Deserialize(reader);
    reader.Close();
}

Is this will deserialize all Meal's to my list? and if not than how to do this? When I'm trying to debug I get exception: Error at XML file (0,0), this (0,0) is confusing, where is problem and how to solve it?

The XML that you shown could be deserialized like this:

  [Serializable()]
  [System.Xml.Serialization.XmlRoot("Menu")]
  public class Menu
  {
     [XmlArray("MainMenu")]
     [XmlArrayItem("Meal", typeof(string))]
     public string[] MainMenu { get; set; }
  }

  public static void Main(string[] args)
  {
     XmlSerializer serializer = new XmlSerializer(typeof(Menu));

     using(StreamReader reader = new StreamReader("MenuXML.xml"))
     {
        Menu menu = (Menu)serializer.Deserialize(reader);
        reader.Close();
     }
  }

If this is ur XML:

<?xml version="1.0" encoding="utf-8" ?>
<Menu>
  <MainMenu>
    <Meal>Example1</Meal>
    <Meal>Example1</Meal>
    <Meal>Example1</Meal>
    <Meal>Example1</Meal>
    <Meal>Example1</Meal>
    <Meal>Example1</Meal>
  </MainMenu>
</Menu>

And I whant to deserialize it as list in class MainMenu:

   public class Menu
   {
      public MainMenu MainMenu{get;set;}
   }
    public class MainMenu
    {

        public List<string> Meal {get; set;}

        public MainMenu()
        {
            Meal = new List<string>();
        }
    }

By method:

private void MenuDeserializer()
{
    Menu menu;
    string path = "MenuXML.xml";

    XmlSerializer serializer = new XmlSerializer(typeof(Menu));

    using(StreamReader reader = new StreamReader(path))
    {
        menu = (Menu)serializer.Deserialize(reader);
    }
}

This is how it shud be...

1 - Remove reader.ReadToEnd(), you're moving the stream from the start so when you come to deserialize it tries to start from the end of the file.

2 - You need to remove the outer Menu element from your XML, your class starts at MainMenu so so should your xml...

<?xml version="1.0" encoding="utf-8" ?>
<MainMenu>
    <Meal>Example1</Meal>
    <Meal>Example1</Meal>
    <Meal>Example1</Meal>
    <Meal>Example1</Meal>
    <Meal>Example1</Meal>
    <Meal>Example1</Meal>
</MainMenu>
