public virtual bool MoveToFollowing(System.Xml.XPath.XPathNodeType type, System.Xml.XPath.XPathNavigator? end);

abstract member MoveToFollowing : System.Xml.XPath.XPathNodeType * System.Xml.XPath.XPathNavigator -> bool
override this.MoveToFollowing : System.Xml.XPath.XPathNodeType * System.Xml.XPath.XPathNavigator -> bool

Public Overridable Function MoveToFollowing (type As XPathNodeType, end As XPathNavigator) As Boolean

參數

type: XPathNodeType

元素的存在 XPathNodeType 。不 XPathNodeType 可能是 Attribute 或 Namespace。

end: XPathNavigator

XPathNavigator位於元素邊界上的物體，該物體XPathNavigator在尋找下一個元素時，電流不會通過。

傳回

Boolean

true若成功XPathNavigator移動;否則，。 false

範例

在以下範例中，將 XPathNavigator 從檔案根contosoBooks.xml移到price 使用此XPathNavigator方法製作物件Clone的克隆。克隆 XPathNavigator的會被放置在 price 元素上的邊界。克隆 XPathNavigator 者位置的變化不會影響原始 XPathNavigator。原始檔案XPathNavigator會透過此contosoBooks.xml方法回到檔案根MoveToRoot目錄。作者的標題以及名字可透過 MoveToFollowing 的方法和 XPathNodeType 的 Textan 取得。 MoveToFollowing該方法會回傳為真，直到達到元素price邊界。

XPathDocument document = new XPathDocument("contosoBooks.xml");
XPathNavigator navigator = document.CreateNavigator();

navigator.MoveToFollowing("price", "http://www.contoso.com/books");
XPathNavigator boundary = navigator.Clone();

navigator.MoveToRoot();

while (navigator.MoveToFollowing(XPathNodeType.Text, boundary))
{
    Console.WriteLine(navigator.OuterXml);
}

Dim document As XPathDocument = New XPathDocument("contosoBooks.xml")
Dim navigator As XPathNavigator = document.CreateNavigator()

navigator.MoveToFollowing("price", "http://www.contoso.com/books")
Dim boundary As XPathNavigator = navigator.Clone()

navigator.MoveToRoot()

While navigator.MoveToFollowing(XPathNodeType.Text, boundary)
    Console.WriteLine(navigator.OuterXml)
End While

此範例會將 contosoBooks.xml 檔案當作輸入。

備註

此 MoveToFollowing 方法不會移動到屬性或命名空間節點。若 XPathNodeType 參數值為 Attribute 或 Namespace，則方法 MoveToFollowing 返回 false 且 XPathNavigator 的位置不變。
若 XPathNavigator 通過的參數邊界未在電流 XPathNavigator 位置之後定位，則忽略該參數。
若 XPathNavigator 參數傳遞的邊界為 null 下一個指定的 XPathNodeType 節點，則該節點位於文件順序中。
這些 MoveToFollowing 方法無法用來移動到屬性或命名空間節點。如果作為參數傳遞的 XPathNavigator 邊界位於屬性或命名空間節點上，則等 XPathNavigator 同於該邊界參數被放置在其父元素的第一個子節點上。這確保邊界參數所在的屬性或命名空間節點 XPathNavigator 的父元素能被此方法匹配。
若 MoveToFollowing 方法返回 false，則 XPathNavigator 的位置不變。

範例

在以下範例中，將 XPathNavigator 從檔案根contosoBooks.xml移到book 使用此XPathNavigator方法製作物件的克隆Clone，並從元素book移動到下一個first-name元素。克隆 XPathNavigator的會被放置在 first-name 元素上的邊界。克隆 XPathNavigator 者位置的變化不會影響原始 XPathNavigator。原始XPathNavigator元件接著嘗試使用price以參數傳遞邊界的方法移動到下一個MoveToFollowing元素。此移動失敗，因為下一個 price 元素超出邊界。原始 XPathNavigator 元素接著嘗試用相同方法移動到邊界前的下一個 title 元素並成功移動。

XPathDocument document = new XPathDocument("contosoBooks.xml");
XPathNavigator navigator = document.CreateNavigator();

navigator.MoveToFollowing("book", "http://www.contoso.com/books");
XPathNavigator boundary = navigator.Clone();
boundary.MoveToFollowing("first-name", "http://www.contoso.com/books");
