binding to datagrid

[hannibal smith]

Hello, I've this class to manage the final result of a competition:

Public Class Player
           
     Private _name As String
     Public Property Name As String
             Get
                 Return _name
             End Get
             Set(ByVal value As String)
          _name = value
     End Set
End Property

     Private _matchScore As Integer()
        Public Property matchScore As Integer()
             Get
                 Return _matchScore
             End Get
             Set(ByVal value As Integer())
                 _matchScore = value
             End Set
         End Property
 Private _points As Integer()
    
     Public Property Points As Integer()
             Get
    
             Return _points
         End Get
  
         Set(ByVal value As Integer())
             _points = value
         End Set
     
     End Property
End Class

and this one for handle the competition:

Public Class Game
    Private _Name As String
    Public Property Name As String
        Get
            Return _Name
        End Get
        Set(ByVal value As String)
            _Name = value
        End Set
    End Property
    Private _nMatch As Integer
    Public Property nMatch As Integer
        Get
            Return _nMatch
        End Get
        Set(ByVal value As Integer)
            _nMatch = value
        End Set
    End Property
    Private _nTarget As Integer
    Public Property nTarget As Integer
        Get
            Return _nTarget
        End Get
        Set(ByVal value As Integer)
            _nTarget = value
        End Set
    End Property
End Class

I declared the competition and add the players with their results:

Public Property myCompetition As Game
 myCompetition = New Game With {.Name = "Test", .nMatch = 2, .nTarget = 55}
GamePlayers.Add(New Player With {.Name = "A", .TotalScore = 5, .matchScore = {2, 3}, .Points = {1, 0, 1, 0, 0, 1, 0, 0, 1, 1}})
GamePlayers.Add(New Player With {.Name = "B", .TotalScore = 9, .matchScore = {4, 5}, .Points = {1, 1, 1, 1, 0, 1, 1, 1, 1, 1}})
GamePlayers.Add(New Player With {.Name = "C", .TotalScore = 9, .matchScore = {5, 4}, .Points = {1, 1, 1, 1, 1, 1, 1, 1, 1, 0}})

Now I would like to show in a datagrid for each match all point (1 for column) and the other property but not the TotalScore.
My problem is how to display Points and matchScore, since I cannot use MappingName in xaml to bind the column since changing the nMatch property .Points's dimension change.
Any advice?
