名稱 Description
IsStartObject(XmlDictionaryReader)

會取得一個值，指定是否 XmlDictionaryReader 位於代表序列化器可反序列化物件的 XML 元素上。
IsStartObject(XmlReader)

判斷 是否 XmlReader 位於可反序列化的物件上。

override this.IsStartObject : System.Xml.XmlDictionaryReader -> bool
Public Overrides Function IsStartObject (reader As XmlDictionaryReader) As Boolean

參數

reader
XmlDictionaryReader

它們 XmlDictionaryReader 用來讀取從 JSON 映射出來的 XML 串流。

傳回

Boolean

true如果讀取器位置正確;否則，。 false

屬性
RequiresDynamicCodeAttribute RequiresUnreferencedCodeAttribute

備註

透過 IsStartObject 檢查物件是否位於 XML 元素上來判斷是否能讀取。 它也會檢查讀取器所在 XML 元素的名稱與命名空間，並將這些值與預期的名稱和命名空間進行比較。 預期名稱可以設定為傳 rootName 入建構子的值（若存在），若缺少則為「根」。 預期命名空間是空字串。

請注意，此方法適用於使用從 JSON 映射的 XML 進階情境。

reader
XmlReader

傳回

Boolean

true如果讀取器位置正確;否則，。 false

備註

此方法檢查讀取器是否位於可反序列化的元素上，若是則回傳 true 。 要返回 true，找到的元素必須具有預期的名稱。
