使用c读取XML内部子节点＃

Question

我想在c＃中读取xml。我能够读取节点'ArrayOfCruisePriceSummaryResponse'，但我如何读取内部节点。

XmlNodeList xmlnode; 
xmlnode = xml.GetElementsByTagName("CruisePriceSummaryResponse"); 

for (int i = 0; i <= xmlnode.Count - 1; i++) 
{ 

} 

使用GetElementsByTagName我能够达到那个节点，但我怎么能读童心。我想从BestFare和FullFare读取TotalPrice和FullFare每个孩子有两个小孩BestFare和FullFare，我需要阅读每个TotalPrice。

P.S我不不想使用LINQ，因为我在SSIS项目中使用VS2008工作，它不支持LINQ。

您可以使用各种SelectNode变体遍历文档并提取数据。

试试这个：

XmlNodeList xmlnodes; 
xmlnodes = xml.GetElementsByTagName("CruisePriceSummaryResponse"); 

for (int i = 0; i < xmlnodes.Count; i++) 
{ 
    XmlNodeList rooms = xmlnodes[i].SelectNodes("RoomSize/CruisePriceSummaryRoomSize"); 
    for(int j = 0; j < rooms.Count; j++) 
    { 
     string bestFare = rooms[j].SelectSingleNode("BestFare/TotalPrice").InnerText; 
     string fullFare = rooms[j].SelectSingleNode("FullFare/TotalPrice").InnerText; 

     // do whatever you need 
    } 
}
