C#中为XML节点添加属性（转）

转一个在C#中为XML节点添加属性的方法


// 设定根节点ItemsCount属性值


// Parameter：


// RootNodeName:根节点名称


// ds:数据集


// Return:


// XmlDataDocument


private XmlDataDocument SetItemsCountAttribute(string strRootNodeName, DataSet ds)




...{


try




...{


XmlDataDocument xmlDoc;


int ItemCount = 0;




ds.DataSetName = strRootNodeName;


ds.EnforceConstraints = false;


if (ds.Tables.Count == 0)




...{


xmlDoc = new XmlDataDocument();




string xml = "<" + strRootNodeName + "></" + strRootNodeName + ">";


xmlDoc.LoadXml(xml);


}


else




...{


ds.Tables[0].TableName = "Item";




ItemCount = ds.Tables[0].Rows.Count;


if (ItemCount == 0)




...{


xmlDoc = new XmlDataDocument();




string xml = "<" + strRootNodeName + "></" + strRootNodeName + ">";


xmlDoc.LoadXml(xml);


}


else




...{


xmlDoc = new XmlDataDocument(ds);


}


}




XmlNode root = xmlDoc.FirstChild;


// 创建节点


XmlNode attrCount = xmlDoc.CreateNode(XmlNodeType.Attribute, "ItemsCount", null);


attrCount.Value = ItemCount.ToString();


// 添加节点属性


root.Attributes.SetNamedItem(attrCount);




return xmlDoc;


}


catch (Exception e)




...{


string strMsg = e.Message;


return null;


}
