C#代码

XmlDocument xdcDocument = new XmlDocument();
xdcDocument.Load(@"E:''Hotel.xml");
var nsmgr = new XmlNamespaceManager(xdcDocument.NameTable);
nsmgr.AddNamespace("ns", "http://www.hotelbeds.com/schemas/2005/06/messages");
var nl = xdcDocument.SelectNodes("/ns:HotelValuedAvailRS/ns:ServiceHotel/ns:HotelInfo", nsmgr);
foreach (XmlNode xndNode in nl)
{
    string name = xndNode["Name"].InnerText;
    var nl3 = xdcDocument.SelectNodes("/ns:HotelValuedAvailRS/ns:ServiceHotel/ns:HotelInfo/ns:ImageList/ns:Image", nsmgr);
    foreach (XmlNode xndNode3 in nl3)
    {
        string url = xndNode3["Url"].InnerText;
        string order = xndNode3["Order"].InnerText;
    }
}

我想阅读每个酒店信息中图片列表下的每个细节。但我的第二个foreach循环所有的图片列表细节，而没有移动到下一个酒店信息与第一个foreach的循环。

var nl3 = xdcDocument.SelectNodes("/ns:HotelValuedAvailRS/ns:ServiceHotel/ns:HotelInfo/ns:ImageList/ns:Image", nsmgr);

var nl3 = xndNode.SelectNodes("ns:ImageList/ns:Image", nsmgr);
