Question

类型'ProblemType'无法序列化。请考虑使用DataContractAttribute属性对其进行标记，并使用DataMemberAttribute属性标记要序列化的所有成员。有关其他受支持的类型，请参阅Microsoft .NET Framework文档。

我的课程很少。当我尝试序列化包含它的类时，即使问题类型被标记，我也会收到数据协定属性错误。

Imports System
Imports System.Runtime.Serialization

<DataContractAttribute()> _
Public Class ProblemType
   Implements ICloneable

     private _serializablePropertyBacking as byte

    <DataMemberAttribute()> _
    Public Property SerializableProperty() As Byte
    Get
        Return _serializablePropertyBacking 
    End Get
    Set(ByVal Value As Byte)
        _serializablePropertyBacking = Value
    End Set
    End Property

    Public Sub New()

    End Sub

    Public Sub New(byval option as boolean)
        If option Then
            _serializableProperty = 1
        End If
    End Sub
End Class

我该怎么做才能解决此错误？

您应该将支持字段设置为数据协定属性，而不是使用它的属性。

Imports System
Imports System.Runtime.Serialization

<DataContractAttribute()> _
Public Class ProblemType
   Implements ICloneable

     <DataMemberAttribute()> _
     private _serializablePropertyBacking as byte


    Public Property SerializableProperty() As Byte
    Get
        Return _serializablePropertyBacking 
    End Get
    Set(ByVal Value As Byte)
        _serializablePropertyBacking = Value
    End Set
    End Property

    Public Sub New()

    End Sub

    Public Sub New(byval option as boolean)
        If option Then
            _serializableProperty = 1
        End If
    End Sub
End Class

WCF序列化问题，错误说类型必须用DataContractAttribute标记，但它已经是
