Question

我无法匿名抓取元素。我不想按名称调用元素。第二个foreach语句只是抓住整个部分，好像它是一个单独的元素。如何在不通过名称调用每个值的情况下循环显示所有值？我愿意做linq语句，但是从我读过的每个例子中，我都看不到如何在不调用每个元素的情况下使用它们。谢谢你的帮助！

public class box
{
    public List<Person> People { get; set; } 
}

public class Person
{
    public Dictionary<string, string> data { get; set; } 
}

/*

<outer>
    <xml>
        <person>
          <data>
            <house>Big</house>
            <cell>911</cell>
            <address>NA</address>
          </data>
        </person>
        <person>
          <data>
            <house>Big</house>
            <cell>911</cell>
            <address>NA</address>
          </data>
        </person>
        <person>
          <data>
            <house>Big</house>
            <cell>911</cell>
            <address>NA</address>
          </data>
        </person>
        <person>
          <data>
            <house>Big</house>
            <cell>911</cell>
            <address>NA</address>
          </data>
        </person>
    </xml>
</outer>

this.box.People = new List<Person>();

foreach (var ele in xml.Descendants("person"))
{
    Person somebody = new Person 
    {
        data = new Dictionary<string, string>(),
    };

    foreach (var temp in ele.Descendants("data")) 
    {
        somebody.data.Add(temp.Name.ToString(), temp.Value.ToString()); 
    }

    this.box.People.Add(somebody); 
}

Answer 1

这有效（测试） - 只是错过了Elements()部分：

foreach (var temp in ele.Descendants("data").Elements()) 
{
    somebody.data.Add(temp.Name.ToString(), temp.Value); 
}

Answer 2

此代码遍历xml文档中的元素和属性。您不必为Elements（）方法提供名称。

XDocument xmlDoc = new XDocument();
foreach (XElement element in xmlDoc.Elements()) {
    // .. Do something with the element
    foreach (XAttribute attribute in element.Attributes()) {
        // .. Do something with the attribute
    }
}

Answer 3

foreach (var temp in ele.Descendants("data")) 
{
    foreach( var valueElem in temp.Elements() )
    {
        somebody.data.Add(valueElem.Name.LocalName, valueElem.Value); 
    }
}
