我一直收到构建错误，我的C＃代码低于

 使用系统;

先谢谢

试试这个：

 System.Xml.XmlDocument xml = new System.Xml.XmlDocument（）; 
 xml.Load（@dirve：\ path \ file.xml）; 
 System.Xml.XmlElement root = xml.DocumentElement; 
 System.Xml.XmlNodeList list = root.GetElementsByTagName（NotificationContentTxt）; 
 foreach（列表中的System.Xml.XmlNode）
 {
 MessageBox.Show（n.InnerText）; 
}

解决方案

Try this:

System.Xml.XmlDocument xml = new System.Xml.XmlDocument();
xml.Load(@"dirve:\path\file.xml");
System.Xml.XmlElement root = xml.DocumentElement;
System.Xml.XmlNodeList list = root.GetElementsByTagName("NotificationContentTxt");
foreach (System.Xml.XmlNode n in list)
{
    MessageBox.Show(n.InnerText);
}
