Question

我在服务中编写了以下代码。

[DataContract]
public class Email
{
    private string senderEmail;
    private MyEmailType emailType;

    [DataMember]
    public string SenderEmail { get { return senderEmail; } set { senderEmail = value; } }
    [DataMember]
    public MyEmailType EmailType { get { return emailType; } set { emailType = value; } }
}

[DataContract]
public enum MyEmailType
{
    [EnumMember]
    EmailType1 = 1,
    [EnumMember]
    EmailType2= 2
}

我将电子邮件对象发送到服务，如下所示：

Email email = new Email();
email.SenderEmail = "someemail@mail.com";
email.EmailType = MyEmailType.EmailType1;

bool isDispatchSuccessful = myClientObject.SendMassProcessEmail(email);

当我到达服务时，SenderEmail属性的值是正确的，但EmailType（枚举）得到0而不是1（EmailType1）。

为什么会这样？

修改：

我尝试将除Email对象之外的MyEmailType变量传递给SendMassProcessEmail，如下所示：

bool isDispatchSuccessful = myClientObject.SendMassProcessEmail(email, MyEmailType.EmailType1);

现在，独立的枚举变量接收到正确的值，但是作为Email类的公共成员的值仍然获得值0.

如果你真的想传递实际值，我认为你应该这样做：

[DataContract]
public enum MyEmailType
{
    [EnumMember(Value = 1)]
    EmailType1 = 1,
    [EnumMember(Value = 2)]
    EmailType2= 2
}

Answer 2

您必须将[DataContract]添加到支持字段：

[DataContract]
public class Email
{
    [DataMember]
    private string senderEmail;

    [DataMember]
    private MyEmailType emailType;

    public string SenderEmail { get { return senderEmail; } set { senderEmail = value; } }
    public MyEmailType EmailType { get { return emailType; } set { emailType = value; } }
}

我遇到了同样的麻烦但在我的情况下，参数名称是错误的。

[ServiceContract]
public interface ISendMail
{
    /// <summary />
    /// <param name="emailType">This parameter should be 'myEmailType'</param>
    [OperationContract]
    void Send(string senderEmail, MyEmailType emailType);
}

在我的情况下，第二个参数是服务器端的myEmailType，但是，当我在客户端创建界面时，我忘记了＆＃39; my＆＃39;。一个愚蠢的错误可以为这个问题带来一些启示。

客户端到WCF：传递枚举值总是为0
