生成XML字符串问题

[linjch]

string b = "";
b = System.Guid.NewGuid().ToString();//获得会话ID
//写XML
XmlDocument xml = new XmlDocument();
XmlDeclaration dec = xml.CreateXmlDeclaration("1.0", "GBK", null);
xml.AppendChild(dec);
XmlNode rootnode = xml.CreateNode(XmlNodeType.Element, "userinfo", "");
xml.AppendChild(rootnode); //添加跟节点
XmlNode childnode1 = xml.CreateNode(XmlNodeType.Element, "sessionID", "");
childnode1.InnerText = b;
rootnode.AppendChild(childnode1);

上面是我写的一个XML文件，没保存的，我想在这个基础上生成XML字符串，用stringbuilder怎么实现，急啊，请高手解决！

string xml = @"<?xml version=""1.0""?>";
XmlDocument doc= new XmlDocument();
doc.LoadXml(xml);
doc.Save("c:\\a.xml");

string xml = @" <?xml version=""1.0""?>";
XmlDocument doc= new XmlDocument();
doc.LoadXml(xml);
doc.Save("c:\\a.xml");

我不想保存到某个路径去，只是想返回这串XML字符串而已

[xmlxslt]

直接拼字符串好了，何必要用XmlDocument

[linjch]

像我上面那样写的，怎么去生成XML字符串，急啊~

在线等待得好辛苦啊，各位高手帮帮忙啊，急急急啊...

StringBuilder sb = new StringBuilder(); myDiv_Img = mImg.Groups["src"].Value + ""; XmlWriterSettings setting = new XmlWriterSettings(); setting.Encoding = Encoding.UTF8; setting.Indent = true; setting.OmitXmlDeclaration = false; XmlWriter writer = XmlWriter.Create(sb, setting); XmlDocument xmlDoc = new XmlDocument(); XmlDeclaration dec = xmlDoc.CreateXmlDeclaration("1.0", "GB2312", null); xmlDoc.AppendChild(dec); //创建根节点  XmlElement root = xmlDoc.CreateElement("Pricture"); xmlDoc.AppendChild(root); foreach (Match mImg in mcImg) { XmlNode pic = xmlDoc.CreateElement("pic"); root.AppendChild(pic); XmlElement title = xmlDoc.CreateElement("href"); title.InnerText = myDiv_Img; pic.AppendChild(title); } xmlDoc.WriteContentTo(writer); writer.Close(); showXML = sb.ToString();

然后，直接把你的XMLDOCUMENT 对象，string xmlstring= xml.ToString();这样试试.xmlstring就是字符串

什么意思? 没明白，能不能说清楚点呢？谢谢！

这段代码有问题~

InnerText 获取或设置节点及其所有子节点的串联值。（从 XmlNode 继承。）
InnerXml 获取或设置表示当前节点子级的标记。

[xray2005]

string xmlstring = xml.OuterXml;

   string b = "";
            b = System.Guid.NewGuid().ToString();//获得会话ID
            //写XML
            XmlDocument xml = new XmlDocument();
            XmlDeclaration dec = xml.CreateXmlDeclaration("1.0", "GBK", null);
            xml.AppendChild(dec);
            XmlNode rootnode = xml.CreateNode(XmlNodeType.Element, "userinfo", "");
            xml.AppendChild(rootnode); //添加跟节点
            XmlNode childnode1 = xml.CreateNode(XmlNodeType.Element, "sessionID", "");
            childnode1.InnerText = b;
            rootnode.AppendChild(childnode1);
            string xmlstring = xml.OuterXml;//就是你的XML字符串。

如果要保存成物理文件，就SaveAs(路径);"

用stringbuilder实现过程：

string b = "";
b = System.Guid.NewGuid().ToString();//获得会话ID
XmlDocument xml = new XmlDocument();
XmlDeclaration dec = xml.CreateXmlDeclaration("1.0", "GBK", null);
xml.AppendChild(dec);
XmlNode rootnode = xml.CreateNode(XmlNodeType.Element, "userinfo", "");
xml.AppendChild(rootnode); //添加跟节点 
XmlNode childnode1 = xml.CreateNode(XmlNodeType.Element, "sessionID", "");
childnode1.InnerText = b;
rootnode.AppendChild(childnode1);


StringBuilder sb = new StringBuilder();//定义StringBuilder 
XmlWriter xw = XmlWriter.Create(sb);
xml.WriteContentTo(xw);   
xw.Flush();
xw.Close();

xmlDoc.OuterXml即可。整篇XML内容。
