编辑：我需要从 NegotiatedRates 元素中获取 MonetaryValue。 对于那个很抱歉。谢谢

【问题讨论】：

这 3 个值是什么？什么领域？

您有兴趣从哪些节点类型中检索哪些值？

更新了抱歉，谢谢

【参考方案1】：

使用LINQtoXML 处理此问题

string filePath = Server.MapPath(@"../YourFileLocation/somexml.xml");

//you can load the XML from file/stream /string etc...

XElement elem = XElement.Load(filePath);
if (elem != null)

    var items = elem.Descendants("NegotiatedRates").ToList();
    foreach (var singleItem in items)
    
        var mo = singleItem.Descendants("MonetaryValue").SingleOrDefault();
        string monetaryValue = mo.Value;
    

根据您提供的 XML，您将在 items 变量和 foreach 中获得 6 个 items，您将在字符串变量 monetaryValue 中获得 MonetaryValue 元素的值
