備註

類別 XmlDsigXPathTransform 可讓您使用 XSLT 轉換來定址 XML 檔。 這個類別會使用 XSLT 將 XML 節點轉換成您想要簽署或加密的其他 XML 節點。

XmlDsigXsltTransform使用 類別，使用 XSLT 轉換簽署或加密 XML 檔的特定部分。

描述 XmlDsigXsltTransform 類別的統一資源識別元 (URI) 是由 欄位定義 XmlDsigXsltTransformUrl 。

如需 XSLT 轉換的詳細資訊，請參閱 W3C XMLDSIG 規格的第 6.6.5 節。

建構函式

XmlDsigXsltTransform()	初始化 XmlDsigXsltTransform 類別的新執行個體。
XmlDsigXsltTransform(Boolean)	使用註解 (如果已指定)，初始化 XmlDsigXsltTransform 類別的新執行個體。

屬性

Algorithm	取得或設定統一資源識別元 (URI)，它識別了目前轉換所執行的演算法。 (繼承來源 Transform)
Context	取得或設定 XmlElement 物件，表示目前 Transform 物件在其下執行的文件內容。 (繼承來源 Transform)
InputTypes	取得型別陣列，其為目前 LoadInput(Object) 物件之 XmlDsigXsltTransform 方法的有效輸入。
OutputTypes	取得可以從目前 GetOutput() 物件的 XmlDsigXsltTransform 方法輸出的型別陣列。
PropagatedNamespaces	取得或設定 Hashtable 物件，內含傳送至簽章的命名空間。 (繼承來源 Transform)
Resolver	設定目前的 XmlResolver 物件。 (繼承來源 Transform)

方法

Equals(Object)	判斷指定的物件是否等於目前的物件。 (繼承來源 Object)
GetDigestedOutput(HashAlgorithm)	在衍生類別中覆寫時，傳回與 Transform 物件關聯的摘要。 (繼承來源 Transform)
GetHashCode()	做為預設雜湊函式。 (繼承來源 Object)
GetInnerXml()	傳回 XmlDsigXsltTransform 物件的參數之 XML 表示，此物件適合納入為 XMLDSIG <Transform> 項目的子項目。
GetOutput()	傳回目前 XmlDsigXsltTransform 物件的輸出。
GetOutput(Type)	傳回型別為 XmlDsigXsltTransform 之目前 Stream 物件的輸出。
GetType()	取得目前執行個體的 Type。 (繼承來源 Object)
GetXml()	傳回目前 Transform 物件的 XML 表示。 (繼承來源 Transform)
LoadInnerXml(XmlNodeList)	將指定的 XmlNodeList 物件剖析為 <Transform> 項目的轉換特定內容，並將目前 XmlDsigXsltTransform 物件的內部狀態設定成與 <Transform> 項目相符。
LoadInput(Object)	將指定的輸入載入目前的 XmlDsigXsltTransform 物件。
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)
