在讀取XML中每次迴圈遍歷xml好麻煩，弄一個linq查詢的方法封裝起來 方便，快捷，舒服
不過最後一個xml的屬性問題，總是想不到用什麼更好的方法解決，各路大神求給意見
/// <summary>
///獲取xml指定節點的值
/// </summary>
/// <param name="path">xml路徑</param>
/// <param name="xmlElement">節點名稱</param>
/// <param name="xmlAttribute">節點屬性</param>
/// <returns></returns>
private static string getXmlValue(string path, string xmlElement, params string[] xmlAttribute)
{
XDocument xmlDoc = XDocument.Load(path);
var results = from c in xmlDoc.Descendants(xmlElement)
select c;
string s = "";
if (xmlAttribute.Length == 0)
{
foreach (var item in results)
{
s = item.Value.ToString();
}
}
else
{
foreach (var item in results)
{
s = item.Attribute(xmlAttribute[0]).Value.ToString();
}
}
return s;
}

private static void setXmlValue(string path, string xmlName, string xmlValue, params string[] xmlAttribute)
{
XDocument xmlDoc = XDocument.Load(path);
if (xmlAttribute.Length == 0)
{
xmlDoc.Element("root").Element(xmlName).SetValue(xmlValue);
}
else
{
xmlDoc.Element("root").Element(xmlName).Attribute(xmlAttribute[0]).SetValue(xmlValue);
}
xmlDoc.Save(path);
