當在衍生類別中覆寫時，會獲得當前節點的限定名稱。

public:
 virtual property System::String ^ Name { System::String ^ get(); };
public:
 abstract property System::String ^ Name { System::String ^ get(); };
public virtual string Name { get; }
public abstract string Name { get; }
member this.Name : string
Public Overridable ReadOnly Property Name As String
Public MustOverride ReadOnly Property Name As String

屬性值

String

目前節點的限定名稱。 例如， Name 是 bk:book 元素 <bk:book>。

回傳的名稱取決於節點的 。NodeType 以下節點類型會回傳列出的值。 其他所有節點類型都會回傳空字串。

節點類型 名稱
Attribute 屬性的名稱。
DocumentType 文件類型名稱。
Element 標記名稱。
EntityReference 所提及的實體名稱。
ProcessingInstruction 處理指令的目標。
XmlDeclaration 字面上的弦 xml。

例外狀況

InvalidOperationException

在先前非同步操作結束前，會呼叫一個 XmlReader 方法。 此時， InvalidOperationException 會拋出「非同步操作已進行中」的訊息。

範例

以下範例讀取一個 XML 檔案並顯示每個節點。

XmlReaderSettings settings = new XmlReaderSettings();
settings.DtdProcessing = DtdProcessing.Parse;
XmlReader reader = XmlReader.Create("items.xml", settings);

reader.MoveToContent();
  // Parse the file and display each of the nodes.
  while (reader.Read()) {
    switch (reader.NodeType) {
      case XmlNodeType.Element:
          Console.Write("<{0}>", reader.Name);
          break;
      case XmlNodeType.Text:
          Console.Write(reader.Value);
          break;
       case XmlNodeType.CDATA:
           Console.Write("<![CDATA[{0}]]>", reader.Value);
           break;
       case XmlNodeType.ProcessingInstruction:
           Console.Write("<?{0} {1}?>", reader.Name, reader.Value);
           break;
       case XmlNodeType.Comment:
           Console.Write("<!--{0}-->", reader.Value);
           break;
       case XmlNodeType.XmlDeclaration:
           Console.Write("<?xml version='1.0'?>");
           break;
       case XmlNodeType.Document:
           break;
       case XmlNodeType.DocumentType:
           Console.Write("<!DOCTYPE {0} [{1}]", reader.Name, reader.Value);
           break;
       case XmlNodeType.EntityReference:
           Console.Write(reader.Name);
           break;
       case XmlNodeType.EndElement:
           Console.Write("</{0}>", reader.Name);
           break;
   }
}
