C#如何创建含有的声明

aiwobiezoukainnn 2012-08-11 10:02:38

XmlDocument xml = new XmlDocument();
XmlNode xmlnode;
// xmlnode = xml.CreateNode(XmlNodeType.XmlDeclaration , "" , "");//创建头文件声明
xmlnode = xml.CreateNode(XmlNodeType.XmlDeclaration , "" , "");
xml.AppendChild(xmlnode);

XmlElement x = xml.CreateElement("班级");
xml.AppendChild(x);

XmlElement subX2 = xml.CreateElement("第一小组");
x.AppendChild(subX2);
XmlElement subChild = xml.CreateElement("学号");
subChild.InnerText = "108253040226";
subX2.AppendChild(subChild);

subChild = xml.CreateElement("姓名");
subChild.InnerText = "甘全福";
subX2.AppendChild(subChild);

subChild = xml.CreateElement("学号");
subChild.InnerText = "108253040227";
subX2.AppendChild(subChild);
subChild = xml.CreateElement("姓名");
subChild.InnerText = "梁玉兰";
subX2.AppendChild(subChild);

subChild = xml.CreateElement("学号");
subChild.InnerText = "108253040228";
subX2.AppendChild(subChild);
subChild = xml.CreateElement("姓名");
subChild.InnerText = "黄海波";
subX2.AppendChild(subChild);

subX2 = xml.CreateElement("第二小组");
x.AppendChild(subX2);
subChild = xml.CreateElement("学号");
subChild.InnerText = "108253040229";
subX2.AppendChild(subChild);
subChild = xml.CreateElement("姓名");
subChild.InnerText = "张建";
subX2.AppendChild(subChild);

subChild = xml.CreateElement("学号");
subChild.InnerText = "108253040230";
subX2.AppendChild(subChild);
subChild = xml.CreateElement("姓名");
subChild.InnerText = "罗玉忠";
subX2.AppendChild(subChild);

subChild = xml.CreateElement("学号");
subChild.InnerText = "108253040231";
subX2.AppendChild(subChild);
subChild = xml.CreateElement("姓名");
subChild.InnerText = "张丽芳";
subX2.AppendChild(subChild);

这样创建的XML文件是有声明的，但我想创建的是，在声明的部分添加属性encoding="utf-8"请各位大侠帮帮忙。

 using (MemoryStream _MemoryStream = new MemoryStream())

            {

                using (XmlTextWriter _XmlWriter = new XmlTextWriter(_MemoryStream, Encoding.UTF8))

                {

                    _XmlWriter.Formatting = Formatting.Indented;

                    _XmlWriter.WriteStartDocument();

                    

                }

                string a = System.Text.Encoding.UTF8.GetString(_MemoryStream.ToArray());

            }
