能简单点不？只要读一句就行了我第二天看C#，所以什么都不懂。
补充：工程是智能编程工程。在winform里
xmldoc.Load(路径);
XmlNode mainnode = xmldoc.SelectSingleNode("websdit ");
string s = mainnode.InnerText；//www.google.com.hk
是这样么
DataSet ds = new DataSet();
ds.ReadXml(Server.MapPath("你项目根目录下xml文件名"));
string sReadXml=ds.tables[i].rows[j][k].toString();
//读出来的是个数据集,里面按照xml的节点生成表,因为不知道你的xml结构,所以ijk得你自己填
是windows mobile开发，好像没有Server
XML就一句：
<?xml version="1.0" encoding="utf-8" ?>
<websdit> http://wap.wdhn.net </websdit>
public static string GetConfig()
{
string elementName = null;
string workPath = Assembly.GetExecutingAssembly().GetName().CodeBase;
string Local = "";
workPath = workPath.Replace("AA.exe", "AAA.xml");
FileStream fs = new FileStream(workPath, FileMode.Open);
XmlTextReader xml = new XmlTextReader(fs);
xml.WhitespaceHandling = WhitespaceHandling.Significant;
while (xml.Read())
{
if (xml.NodeType == XmlNodeType.Element)
{
elementName = xml.Name;
}
else if (xml.NodeType == XmlNodeType.Text)
{
switch (elementName)
{
case "Local":
Local = xml.Value;
break;
default:
break;
}
}
}
xml.Close();
fs.Close();
return Local;
}
谢谢！~~~~
能简单点不？。。就一句：
<?xml version="1.0" encoding="utf-8" ?>
<websdit> http://wap.wdhn.net </websdit>
XML文件就在工程根目录下，config.xml。非常谢谢~~~
xmlDoc.Load(Server.MapPath("~/123.xml")); XmlNode Node = xmlDoc["websdit"];
string xxx= Node.InnerText;
够简单了吧。。
xmldoc.Load(AppDomain.CurrentDomain.BaseDirectory+“config.xml”);
XmlNode mainnode = xmldoc.SelectSingleNode("websdit ");
string s = mainnode.InnerText；//www.google.com.hk AppDomain.CurrentDomain.BaseDirectory就代表根目录，bin-》dubug文件夹下
是这个意思么？
呃不是。。开始可能没说清楚，不好意思。config.xml就是在建好的工程的工程文件夹下。和源文件是在同一个目录下。
谢谢~~~ 够简单但是还是没解决问题，是在w智能设备编程工程下。没有Server

晕！ 我哪有重复粘贴了！ 那是一个对xml操作类！
路径的话建议写在配置文件里用ConfigurationManager读取，这样最灵活
