C#：如何指定XML文件保存的编码？

[Qiaorui]

由于XML很小，偶用XmlDocument来生成
XmlDocument xmldoc = new XmlDocument();
XmlNode nodePI = xmldoc.CreateProcessingInstruction("xml","version=\"1.0\" encoding=\"gb2312\"");
...//生成XML节点
xmldoc.Save("test.xml");

在代码中，XML的文档的encoding指定为gb2312，但保存XML文件时，文件的编码却是UTF-8，二者完全不同，如果XML含有中文，就不行了。怎样指定XML文件保存的编码？

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);

}
}

直接用encoding="UTF-8"不行吗？

[Alldim]

FileStream fs=new FileStream(Server.MapPath("test.xml"),FileMode.Create);
XmlTextWriter xtr=new XmlTextWriter(fs,System.Text.Encoding.GetEncoding("gb2312"));
xtr.Formatting=Formatting.Indented;
xtr.Indentation=0;
xtr.WriteStartDocument();
ds.WriteXml(xtr);
xtr.Close();
fs.Close();
