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

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

}

使用 GetElementsByTagName 我可以到达该节点，但我如何读取内部孩子。我想从 BestFare 和 FullFare 中读取 TotalPrice 每个孩子有两个内在孩子 BestFare 和 FullFare，我需要读取每个 TotalPrice .

P.S 我不想使用 LINQ，因为我正在使用 VS2008 处理 SSIS 项目，它不支持 LINQ。

您可以使用各种 SelectNode 变体来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
}
}
