示例

下面的代码示例演示了属性 MessagePropertyAttribute 的使用。

[MessageContractAttribute]
public class CustomMessage
{
    private Person internalPerson;
    [MessageProperty]
    private int a = 23;
    [MessageBodyMember(Name="Person")]
    public PersonType Data
    {
        get
        {
            return internalPerson;
        }
        set
        {
            this.internalPerson = (Person)value;
        }
    }
}

<MessageContractAttribute> _
Public Class CustomMessage
    Private internalPerson As Person
    <MessageProperty> _
    Private a As Integer = 23
    <MessageBodyMember(Name:="Person")> _
    Public Property Data() As PersonType
        Get
            Return internalPerson
        End Get
        Set(ByVal value As PersonType)
            Me.internalPerson = CType(value, Person)
        End Set
    End Property
End Class

注解

使用 MessagePropertyAttribute 属性将数据附加到自定义消息类型，因为它通过 Windows Communication Foundation （WCF） 系统而不将数据序列化为 SOAP 消息。
