Question

我编写了一个类，并希望它的属性显示在DataGridView控件中。但是，只有一些属性可用于绑定到列。如何使所有公共属性可用于绑定到列？以下是我的课程，IndividualServices属性不会出现在设计师中，而其他属性则是。

Public Class Patient
Private _name As String
Private _id As String
Private _services As New List(Of Service)


Property Name As String
    Get
        Return _name
    End Get
    Set(value As String)
        _name = value
    End Set
End Property
Property ID As String
    Get
        Return _id
    End Get
    Set(value As String)
        _id = value
    End Set
End Property
Public ReadOnly Property Services As List(Of Service)
    Get
        Return _services
    End Get
End Property
ReadOnly Property TotalServices As Integer
    Get
        Dim i As Integer = 0
        For Each s As Service In _services
            i = i + s.Count
        Next s
        Return i
    End Get

End Property
ReadOnly Property IndividualServices As Integer
    Get
        Return _services.Count
    End Get
End Property

Public Sub Add(sName As String, sCode As String)
    Dim bool As Boolean = False
    If _services.Count = 0 Then GoTo firstThrough
    For Each s As Service In _services
        If s.Name = sName Then
            s.Add(1)
            bool = True
            Exit For
        End If
    Next
    If Not bool Then
firstThrough:
        Dim newSer As New Service
        newSer.Name = sName
        newSer.Code = sCode
        newSer.Count = 1
        _services.Add(newSer)
    End If
End Sub
End Class
