[英]WCF and the [DataMember] Attribute
I have the following (abbreviated) class that is sent and received to/from the client via WCF: 我有以下(缩写)类通过WCF发送到客户端/从客户端接收:
public class Sparetime : ChartConfigurationBase, IChartConfiguration
{
[DataMember]
public int SparetimeConfigurationId { get; set; }
public Single FeederOffRate { get; set; }
}
Notice the first property uses the DataMember attribute and the second doesn't. 请注意,第一个属性使用DataMember属性,第二个属性不使用。 Am I correct that only the first property would get serialized and sent to the client when a WCF call is made?
我是否更正,在进行WCF调用时,只有第一个属性会被序列化并发送给客户端?
Yes, you are right, the MSDN documentation specifies it : 是的,你是对的, MSDN文档指定它:
When applied to the member of a type, specifies that the member is part of a data contract and is serializable by the DataContractSerializer.
应用于类型成员时,指定该成员是数据协定的一部分,并且可由DataContractSerializer序列化。
You should add DataContract attribute to your class to make it serializable : 您应该将DataContract属性添加到您的类中以使其可序列化:
[DataContract]
public class Sparetime : ChartConfigurationBase, IChartConfiguration
{
}
Note that FeederOffRate
will be set to its default value (null for reference types). 请注意,
FeederOffRate
将设置为其默认值(引用类型为null)。
