XmlDeclaration.Encoding 屬性

public:
 property System::String ^ Encoding { System::String ^ get(); void set(System::String ^ value); };

public string Encoding { get; set; }

member this.Encoding : string with get, set

Public Property Encoding As String

屬性值

有效的字元編碼名稱。 XML 最常支援的字元編碼名稱如下：

此為選用值。 若值未被設定，此屬性會回傳 String.Empty。

若未包含編碼屬性，撰寫或儲存文件時會假設採用 UTF-8 編碼。

範例

以下範例建立一個 XmlDeclaration 節點並將其加入 XML 文件中。

using System;
using System.IO;
using System.Xml;

public class Sample {

  public static void Main() {

    // Create and load the XML document.
    XmlDocument doc = new XmlDocument();
    string xmlString = "<book><title>Oberon's Legacy</title></book>";
    doc.Load(new StringReader(xmlString));

    // Create an XML declaration.
    XmlDeclaration xmldecl;
    xmldecl = doc.CreateXmlDeclaration("1.0",null,null);
    xmldecl.Encoding="UTF-8";
    xmldecl.Standalone="yes";

    // Add the new node to the document.
    XmlElement root = doc.DocumentElement;
    doc.InsertBefore(xmldecl, root);

    // Display the modified XML document
    Console.WriteLine(doc.OuterXml);
  }
}

Imports System.IO
Imports System.Xml

public class Sample 

  public shared sub Main() 
   
    ' Create and load the XML document.
    Dim doc as XmlDocument = new XmlDocument()
    Dim xmlString as string = "<book><title>Oberon's Legacy</title></book>"
    doc.Load(new StringReader(xmlString))
  
    ' Create an XML declaration. 
    Dim xmldecl as XmlDeclaration 
    xmldecl = doc.CreateXmlDeclaration("1.0",nothing, nothing)
    xmldecl.Encoding="UTF-8"
    xmldecl.Standalone="yes"     
      
    ' Add the new node to the document.
    Dim root as XmlElement = doc.DocumentElement
    doc.InsertBefore(xmldecl, root)
    
    ' Display the modified XML document 
    Console.WriteLine(doc.OuterXml)
      
  end sub
end class

備註

與大多數 XML 屬性不同，編碼屬性值不區分大小寫。 這是因為編碼字元名稱遵循 ISO 及網際網路號碼授權機構（IANA）標準。
