備註

類別的主要用途 SoapMessage 是 SOAP 延伸模組，代表 SOAP 要求或 SOAP 回應中的資料。 ProcessMessage呼叫方法時， SoapExtension 會 SoapMessage SoapMessageStage 在每個接收。您可以選擇如何處理 SoapMessage 的特定 SOAP 擴充功能。常見的 SOAP 延伸模組包括加密和壓縮。

SOAP 延伸模組可以套用至使用 ASP.NET 或 XML Web 服務用戶端建立的 XML Web 服務方法。當 SOAP 延伸模組套用至 XML Web 服務方法時， ProcessMessage 方法會接收衍生自 SoapMessage 的 SoapServerMessage 實例。同樣地，當 SOAP 延伸模組套用至 XML Web 服務用戶端時， ProcessMessage 會收到的 SoapClientMessage 實例。

屬性

Action	當在衍生類別中覆寫時，取得 SOAP 要求或 SOAP 回應的 SOAPAction HTTP 要求標頭欄位。
ContentEncoding	取得或設定 `Content-Encoding` HTTP 標頭的內容。
ContentType	取得或設定 SOAP 要求或 SOAP 回應的 HTTP `Content-Type`。
Exception	取得 SoapException，其因呼叫 XML Web Service 方法而造成的。
Headers	套用至目前 SOAP 要求或 SOAP 回應的 SOAP 標頭集合。
MethodInfo	當在衍生類別中覆寫時，取得 SOAP 要求所適用的 XML Web Service 方法的方法原型 (Prototype) 表示。
OneWay	取得值，指出套用至 XML Web Service 方法之 OneWay 或 SoapDocumentMethodAttribute 屬性 (Attribute) 的 SoapRpcMethodAttribute 屬性 (Property)。
SoapVersion	取得用來與 XML Web Service 通訊的 SOAP 通訊協定版本。
Stage	取得 SoapMessageStage 的 SoapMessage。
Stream	取得以 Stream 形式表示的 SOAP 要求或 SOAP 回應的資料。
Url	在衍生類別中覆寫時，取得 XML Web Service 的基礎 URL。

方法

EnsureInStage()	當在衍生類別中覆寫時，判斷提示 (Assert) 目前的 SoapMessageStage 是可以取得 in 參數的階段。
EnsureOutStage()	當在衍生類別中覆寫時，判斷提示目前的 SoapMessageStage 階段是可以取得 out 參數的階段。
EnsureStage(SoapMessageStage)	確認呼叫 XML Web Service 方法的 SoapMessageStage 是傳入的階段。如果目前的處理階段不是傳入的其中一個階段，則擲回例外狀況。
Equals(Object)	判斷指定的物件是否等於目前的物件。 (繼承來源 Object)
GetHashCode()	做為預設雜湊函式。 (繼承來源 Object)
GetInParameterValue(Int32)	在指定的索引處取得傳入 XML Web Service 方法的參數。
GetOutParameterValue(Int32)	在指定索引處取得傳入 XML Web Service 方法的 out 參數。
GetReturnValue()	取得 XML Web Service 方法的傳回值。
GetType()	取得目前執行個體的 Type。 (繼承來源 Object)
MemberwiseClone()	建立目前 Object 的淺層複製。 (繼承來源 Object)
ToString()	傳回代表目前物件的字串。 (繼承來源 Object)
