Gets or sets the encoding level of the XML document.

 property System::String ^ Encoding { System::String ^ get(); void set(System::String ^ value); };public string Encoding { get; set; }member this.Encoding : string with get, setPublic Property Encoding As StringProperty Value
The valid character encoding name. The most commonly supported character encoding names for XML are the following:
| Category | Encoding Names | 
|---|---|
| Unicode | UTF-8, UTF-16 | 
| ISO 10646 | ISO-10646-UCS-2, ISO-10646-UCS-4 | 
| ISO 8859 | ISO-8859-n (where "n" is a digit from 1 to 9) | 
| JIS X-0208-1997 | ISO-2022-JP, Shift_JIS, EUC-JP | 
This value is optional. If a value is not set, this property returns String.Empty.
If an encoding attribute is not included, UTF-8 encoding is assumed when the document is written or saved out.
Examples
The following example creates an XmlDeclaration node and adds it to an XML document.
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
Remarks
Unlike most XML attributes, encoding attribute values are not case-sensitive. This is because encoding character names follow ISO and Internet Assigned Numbers Authority (IANA) standards.
