求救！那位大哥能提供一份读写XML的公共类啊，小弟急用！在线等！

[KJ_Wang]

写个简单的结构吧.
public class InputOutputXML
{
public void InputFromXML(DataSet ds,string strPathAndFile)
{
ds.readXML(strPathAndFile);
}
public void OutputToXML(DataSet ds,string strPathAndFile)
{
ds.WriteXml(strPathAndFile);
}
}
这样好像可以.

public class XmlControl
{
protected string strXmlFile;
protected XmlDocument objXmlDoc = new XmlDocument();

public XmlControl(string XmlFile)
{
//
// TODO: 在這裡加入建構函式的程式碼
//
try
{
objXmlDoc.Load(XmlFile);
}
catch (System.Exception ex)
{
throw ex;
}
strXmlFile = XmlFile;
}

public DataView GetData(string XmlPathNode)
{
//查找數據。返回一個DataView
DataSet ds = new DataSet();
StringReader read = new StringReader(objXmlDoc.SelectSingleNode(XmlPathNode).OuterXml);
ds.ReadXml(read);
return ds.Tables[0].DefaultView;
}

public void Replace(string XmlPathNode,string Content)
{
//更新節點內容。
objXmlDoc.SelectSingleNode(XmlPathNode).InnerText = Content;
}

public void Delete(string Node)
{
//刪除一個節點。
string mainNode = Node.Substring(0,Node.LastIndexOf("/"));
objXmlDoc.SelectSingleNode(mainNode).RemoveChild(objXmlDoc.SelectSingleNode(Node));
}

public void InsertNode(string MainNode,string ChildNode,string Element,string Content)
{
//插入一節點和此節點的一子節點。

XmlElement objChildNode = objXmlDoc.CreateElement(ChildNode);
objRootNode.AppendChild(objChildNode);
XmlElement objElement = objXmlDoc.CreateElement(Element);

}

public void InsertElement(string MainNode,string Element,string Attrib,string AttribContent,string Content)
{
//插入一個節點，帶一屬性。
XmlNode objNode = objXmlDoc.SelectSingleNode(MainNode);
XmlElement objElement = objXmlDoc.CreateElement(Element);
objElement.SetAttribute(Attrib,AttribContent);
objElement.InnerText = Content;
objNode.AppendChild(objElement);
}

public void InsertElement(string MainNode,string Element,string Content)
{
//插入一個節點，不帶屬性。
XmlNode objNode = objXmlDoc.SelectSingleNode(MainNode);
XmlElement objElement = objXmlDoc.CreateElement(Element);
objElement.InnerText = Content;
objNode.AppendChild(objElement);
}

public void Save()
{
//保存文檔。
try

objXmlDoc.Save(strXmlFile);
}
catch (System.Exception ex)
{
throw ex;

我帮你找的，不过我用了，还行.

盖茨大叔的xmldocument, xmltextreader, xmltextwriter就挺好的

XmlDocument方法或者XmlTextWriter,XmlTextReader
