注解

类的主要用途 SoapMessage 是 SOAP 扩展，表示 SOAP 请求或 SOAP 响应中的数据。 ProcessMessage调用方法时， SoapExtension 在每个 SoapMessageStage处接收 SoapMessage 。由特定的 SOAP 扩展选择如何处理 SoapMessage。常见的 SOAP 扩展包括加密和压缩。

SOAP 扩展可以应用于使用 ASP.NET 或 XML Web 服务客户端创建的 XML Web 服务方法之一或两者。将 SOAP 扩展应用于 XML Web 服务方法时， ProcessMessage 方法接收派生自 SoapMessage的 SoapServerMessage实例。同样，当 SOAP 扩展应用于 XML Web 服务客户端时， ProcessMessage 将接收的 SoapClientMessage实例。

属性

Action	当在派生类中被重写时，获取用于 SOAP 请求或 SOAP 响应的 SOAPAction HTTP 请求标头字段。
ContentEncoding	获取或设置 `Content-Encoding` HTTP 标头的内容。
ContentType	获取或设置 SOAP 请求或 SOAP 响应的 HTTP `Content-Type`。
Exception	从对 XML Web services 方法的调用中获取 SoapException。
Headers	应用于当前 SOAP 请求或 SOAP 响应的 SOAP 标头的集合。
MethodInfo	当在派生类中重写时，获取为要其发出 SOAP 请求的 XML Web services 方法的方法原型的表示形式。
OneWay	获取一个值，该值指示应用于 XML Web services 方法的 OneWay 或 SoapDocumentMethodAttribute 特性的 SoapRpcMethodAttribute 属性。
SoapVersion	获取用于与 XML Web services 进行通信的 SOAP 协议的版本。
Stage	获取 SoapMessageStage 的 SoapMessage。
Stream	获取以 Stream 形式表示 SOAP 请求或 SOAP 响应的数据。
Url	当在派生类中重写时，获取 XML Web services 的基 URL。

方法

EnsureInStage()	当在派生类中被重写时，断言当前 SoapMessageStage 为可以使用 in 参数的阶段。
EnsureOutStage()	当在派生类中被重写时，断言当前 SoapMessageStage 阶段是不可以使用 out 参数的阶段。
EnsureStage(SoapMessageStage)	确保对 XML Web services 方法的调用的 SoapMessageStage 是传入的阶段。如果当前处理阶段不是传入的阶段之一，则引发异常。
Equals(Object)	确定指定对象是否等于当前对象。 (继承自 Object)
GetHashCode()	作为默认哈希函数。 (继承自 Object)
GetInParameterValue(Int32)	在指定索引处获取传递到 XML Web services 方法中的参数。
GetOutParameterValue(Int32)	在指定索引处获取传递到 XML Web services 方法中的输出参数。
GetReturnValue()	获取 XML Web services 方法的返回值。
GetType()	获取当前实例的 Type。 (继承自 Object)
MemberwiseClone()	创建当前 Object 的浅表副本。 (继承自 Object)
ToString()	返回表示当前对象的字符串。 (继承自 Object)
