xml的问题

[vwd]

用ds.WriteXml("d:\\q.xml");
写出一个xml文件,如下:<?xml version="1.0" standalone="yes"?>
怎样能加上 encoding="GB2312"

[vwd]

to idiotzeng:试过了,不行
ds.WriteXml(new XmlTextWriter("d:\\q.xml",System.Text.Encoding.GetEncoding("GB2312")));
写出来后,连<?xml version="1.0" standalone="yes"?>都没了

[MikeWKL]

xmlWriter = new XmlTextWriter("d:\\q.xml", Encoding.Default);

源码：
XmlTextWriter writer = new XmlTextWriter("d:\\q.xml", System.Text.Encoding.Default);
writer.WriteStartDocument();
writer.Formatting = Formatting.Indented;
writer.WriteStartElement("Describe");
writer.WriteStartElement("Define");
writer.WriteStartElement("Title");
writer.WriteString("1");
writer.WriteEndElement();
writer.WriteStartElement("Dimension");
writer.WriteString("2");
writer.WriteEndElement();

writer.WriteEndDocument();
writer.Close();

结果：
<?xml version="1.0" encoding="gb2312"?>
<Describe>
<Define>
<Title>1</Title>
<Dimension>2</Dimension>
</Define>
</Describe>

我刚刚运行的，不知是不是你要的结果

up一下，呵呵，我也不知道

[idiotzeng]

ds.WriteXml(new XmlTextWriter(....))

[idiotzeng]

暂时找不到其他办法。。。。
string s = this.dataSet1.GetXml();
System.IO.StreamWriter fs = new System.IO.StreamWriter("d:\\qq.xml",false);
fs.WriteLine("<?xml version='1.0' encoding='gb2312'?>");
fs.Write(s);
fs.Close();
