示例

下面的示例应用 DataContractFormatAttribute 并将 Style 属性设置为 RpcThe following example applies the DataContractFormatAttribute and sets the Style property to Rpc. RPC 样式在 Web 服务描述语言规范 (WSDL) 中描述。The RPC style is described in the Web Service Description Language specification (WSDL).

[ServiceContract, DataContractFormat(Style = OperationFormatStyle.Rpc)]
interface ICalculator
{
    [OperationContract, DataContractFormat(Style = OperationFormatStyle.Rpc)]
    double Add(double a, double b);

    [OperationContract, DataContractFormat(Style = OperationFormatStyle.Document)]            
    double Subtract(double a, double b);
}
<ServiceContract(), DataContractFormat(Style := OperationFormatStyle.Rpc)>  _
Interface ICalculator
    <OperationContract(), DataContractFormat(Style := OperationFormatStyle.Rpc)>  _
    Function Add(ByVal a As Double, ByVal b As Double) As Double 
    
    <OperationContract(), DataContractFormat(Style := OperationFormatStyle.Document)>  _
    Function Subtract(ByVal a As Double, ByVal b As Double) As Double 
End Interface 
<ServiceContract(), DataContractFormat(Style := OperationFormatStyle.Rpc)>  _
Interface ICalculator
    <OperationContract(), DataContractFormat(Style := OperationFormatStyle.Rpc)>  _
    Function Add(ByVal a As Double, ByVal b As Double) As Double 
    
    <OperationContract(), DataContractFormat(Style := OperationFormatStyle.Document)>  _
    Function Subtract(ByVal a As Double, ByVal b As Double) As Double 
End Interface 

注解

此属性与 XmlSerializerFormatAttribute 属性类似。This attribute is similar to the XmlSerializerFormatAttribute attribute. 这两种属性均可应用于方法或类。Both attributes can be applied to either a method or a class.

可以对方法应用两个属性中的一个,但不能同时应用。A method can have either of the two attributes applied, but not both. 任何尚未应用任意一种属性的操作都将使用应用于包含类的属性。Any operation that has neither applied will use the attribute applied to the containing class. 如果包含类未应用这两种属性中的任意一种,则使用 DataContractSerializerIf the containing class does not have either attribute applied, the DataContractSerializer is used.

应用该属性还会导致在运行时创建 DataContractSerializerOperationBehaviorApplying the attribute also causes a DataContractSerializerOperationBehavior to be created at run time. 该行为允许在运行时自定义序列化程序行为。The behavior allows customization at run time of the serializer behavior.
