SoapClientMessage.OneWay 属性

定义

命名空间:

System.Web.Services.Protocols

程序集:

System.Web.Services.dll

获取一个值，该值指示客户端是否等待服务器处理完 XML Web services 方法。

public:
 virtual property bool OneWay { bool get(); };

public override bool OneWay { get; }

member this.OneWay : bool

Public Overrides ReadOnly Property OneWay As Boolean

属性值

Boolean

如果客户端不等待服务器完成对方法的处理，则为 true。

示例

以下代码片段是 SOAP 扩展的一部分，用于记录 XML Web 服务客户端发送和接收的 SOAP 消息。 当属性为单向时，此特定片段将输出到该日志文件中一个短语，指出 XML Web 服务方法是true单向的OneWay。

注解

SoapDocumentMethodAttribute或SoapRpcMethodAttribute应用于 XML Web 服务方法或 XML Web 服务客户端可以通过设置OneWay属性的属性来指定 XML Web 服务方法是否一种方式。

可以在任何SoapMessageStage期间访问该OneWay属性。
