備註

大部分的 LINQ to XMLLINQ to XML 擴充方法都是用於 LINQLINQ 查詢中的軸方法。Most of the LINQ to XMLLINQ to XML extension methods are axis methods that are used in LINQLINQ queries. 此類別中的方法會在集合上運作,並傳回集合。The methods in this class operate on collections and return collections. 這些方法會列舉來源集合、在集合中的每個專案上呼叫適當的軸方法,以及串連結果。These methods enumerate the source collection, call the appropriate axis method on each item in the collection, and concatenate the results.

但這兩個 Remove 擴充方法並不是座標軸方法。The two Remove extension methods are not axis methods, however. 這些方法會從 XML 樹狀結構移除屬性或節點。These methods remove attributes or nodes from the XML tree.

請注意,在 XElementXDocumentXNode 類別中,有另一種軸方法的分類。Note that there is another category of axis methods, implemented in the XElement, XDocument, and XNode classes. 這些其他軸方法會在單一物件上運作,並傳回 XElementXAttributeXNode 物件的集合。These other axis methods operate on a single object, and return a collection of XElement, XAttribute, or XNode objects.

所有的軸擴充方法都會使用延後執行。All of the axis extension methods use deferred execution.
