MVC读取web.config文件的节点值

XmlDocument document = new XmlDocument();
document.Load(CofigFilesName); //CofigFilesName：文件路径  如web/web.config
XmlNodeList childNodes = document.SelectSingleNode("configuration").ChildNodes; //configuration节点名称
XmlNode rootNode = childNodes[0];

foreach (XmlNode n in childNodes)
{
if ((n.Name == "Project")) //读取“Project”的节点
{
rootNode = n;
}
}

string projectName ="";

foreach (XmlNode node in rootNode.ChildNodes)
{

     if (node.Name == "Name")

     {
　　  projectName  = nodevalue;//读取节点的值

      }

}
