DiscoveryDocument

範例

下列程式碼範例會使用 Read 從檔案讀取探索檔，並使用 方法將它寫回檔案 Write 。

備註

XML Web 服務探索牽涉到在 URL 中探索可用的 XML Web 服務。 URL 通常會指向探索檔，其通常副檔名為 .disco。 探索檔是 XML 檔，包含 XML Web 服務存在相關資訊的參考，例如服務描述、XML 架構定義 (XSD) 語言架構或其他探索檔。 這個類別代表探索檔的內容;其中 屬性 References 包含探索檔內所包含的參考清單。

建構函式

DiscoveryDocument()

初始化 DiscoveryDocument 類別的新執行個體。

欄位

Namespace

探索文件的探索 XML 項目的命名空間。

屬性

References

內含於探索文件的參考清單。

方法

CanRead(XmlReader)	傳回值，指出傳遞的 XmlReader 是否可還原序列化為 DiscoveryDocument。
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)
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)
Read(Stream)	從傳遞的 DiscoveryDocument 讀取並傳回 Stream。
Read(TextReader)	從傳遞的 DiscoveryDocument 讀取並傳回 TextReader。
Read(XmlReader)	從傳遞的 DiscoveryDocument 讀取並傳回 XmlReader。
ToString()	傳回代表目前物件的字串。 (繼承來源 Object)
Write(Stream)	將這個 DiscoveryDocument 寫入至傳遞的 Stream。
Write(TextWriter)	將這個 DiscoveryDocument 寫入至傳遞的 TextWriter。
Write(XmlWriter)	將這個 DiscoveryDocument 寫入至傳遞的 XmlWriter。
