在C＃中反序列化XML嵌套集合

因此，在反序列化嵌套在其中的XML的XML時遇到問題。在嵌套集合（Grades）被添加之前，我能夠反序列化它，但之後一直未能。任何幫助將是偉大的！在C＃中反序列化XML嵌套集合

下面是什麼XML序列化爲：

<?xml version="1.0" encoding="utf-8"?> 
<ListOfPlayers xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xmlns:xsd="http://www.w3.org/2001/XMLSchema"> 
<Player> 
    <FirstName>Michael</FirstName> 
    <LastName>Jordan</LastName> 
    <EmailAddress>[email protected]</EmailAddress> 
    <PhoneNumber>206-227-6000</PhoneNumber> 
    <NumberOfExtraTeamsWillingToFill>2</NumberOfExtraTeamsWillingToFill> 
    <IsActive>true</IsActive> 
    <InactiveReason /> 
    <PlayerNotes /> 
    <GradesCurrentlyEnrolled> 
     <Grades>First</Grades> 
     <Grades>Second</Grades> 
    </GradesCurrentlyEnrolled> 
    </Player> 
<Player> 
    <FirstName>Magic</FirstName> 
    <LastName>Johnson</LastName> 
    <EmailAddress>[email protected]</EmailAddress> 
    <PhoneNumber>206-227-6000</PhoneNumber> 
    <NumberOfExtraTeamsWillingToFill>3</NumberOfExtraTeamsWillingToFill> 
    <IsActive>true</IsActive> 
    <InactiveReason /> 
    <PlayerNotes>Has a new baby</PlayerNotes> 
    <GradesCurrentlyEnrolled> 
     <Grades>Sixth</Grades> 
     <Grades>Eighth</Grades> 
    </GradesCurrentlyEnrolled> 
    </Player> 
</ListOfPlayers>

這裏是代碼爲玩家類：

public class Player : ModelBase 
    { 
    public Player() 
    { 
     FirstName = ""; 
     LastName = ""; 
     PhoneNumber = ""; 
     EmailAddress = ""; 
     NumberOfExtraTeamsWillingToFill = 0; 
     IsActive = true; 
     InactiveReason = ""; 
     PlayerNotes = ""; 
     GradesCurrentlyEnrolled = new ListOfGrades(); 
    } 

    public Player(string firstName, string lastName, string phoneNumber, string emailAddress, int numberOfExtraTeamsWillingToFill, 
     bool isActive, string inactiveReason, ListOfGrades gradesCurrentlyEnrolled, string playerNotes) 
    { 
     FirstName = firstName; 
     LastName = lastName; 
     PhoneNumber = phoneNumber; 
     EmailAddress = emailAddress; 
     NumberOfExtraTeamsWillingToFill = numberOfExtraTeamsWillingToFill; 
     IsActive = isActive; 
     InactiveReason = inactiveReason; 
     PlayerNotes = playerNotes; 
     GradesCurrentlyEnrolled = gradesCurrentlyEnrolled; 
    } 

    // IsPlayerFloating 
    public bool IsPlayerFloating 
    { 
     get 
     { 
      return (GradesCurrentlyEnrolled.Count == 0); 
     } 
    } 

    // GradesCurrentlyEnrolled 
    private ListOfGrades _gradesCurrentlyEnrolled; 
    public ListOfGrades GradesCurrentlyEnrolled 
    { 
     get { return _gradesCurrentlyEnrolled; } 
     set { _gradesCurrentlyEnrolled = value;}   //SendPropertyChanged("GradesCurrentlyEnrolled"); } 
    } 

}

這是序列化和反序列化的代碼：

 private void LoadAllPlayers() 
    { 
     ListOfPlayer _playersForSerial; 
     Player testPlayer; 
     XmlSerializer serializer = new XmlSerializer(typeof(Player)); 

     StreamReader reader = new StreamReader(filename); 
     testPlayer = (Player)serializer.Deserialize(reader); 
     reader.Close(); 

     Players.Add(new PlayerViewModel(testPlayer)); 

     foreach (Player pv in _playersForSerial) 
     { 
      Players.Add(new PlayerViewModel()); 
     } 

    } 

    public void SaveAllPlayers() 
    { 
     ListOfPlayer _playersForSerial = new ListOfPlayer(); 

     //Creates a list of Players fromt eh ViewModels 
     foreach (PlayerViewModel pv in Players) 
     { 
      _playersForSerial.Add(pv.GetPlayer); 

     } 

     // Note that only the collection is serialized -- not the 
     // CollectionName or any other public property of the class. 
     XmlSerializer x = new XmlSerializer(typeof(ListOfPlayer)); 
     TextWriter writer = new StreamWriter(filename); 
     x.Serialize(writer, _playersForSerial); 
     writer.Close(); 
    }

另外這裏是該系列的代碼：

[XmlRootAttribute("ListOfPlayers")] 
public class ListOfPlayer : ObservableCollection<Player> 
{ 
} 

[XmlRoot("GradesList")] 
public class ListOfGrades : List<Grades> 
{ 
}

而且等級是一個枚舉：再次

public enum Grades 
{ 
    PreK, 
    K, 
    First, 
    Second, 
    Third, 
    Fourth, 
    Fifth, 
    Sixth, 
    Seventh, 
    Eighth 
}

謝謝！對不起所有的信息。

保持ListOfGrades相同的玩家類屬性名的XMLRoot標籤。它會工作。目前，ListOfGrades正在查找根節點「GradesList」，該節點不存在但「GradesCurrentlyEnrolled」存在，它是屬性的名稱。避免給XMlRoot ListOfGrades，它可能會解決問題 – Akanksha

看來，無論ListOfGrades的XMLRoot是什麼，它仍然給我一個XamlParseException當我嘗試和反序列化。當我通過它時總是打破： testPlayer =（Player）serializer.Deserialize（reader）; – user2914282

你應該提供有關其他類型的XmlSerializer這樣的信息：

XmlSerializer serializer = new XmlSerializer(typeof(Player),new []{typeof(ListOfGrades)});

這會在嘗試序列化播放器時生成InvalidOperationException。 – user2914282
