从 XML 标签中提取键值 C# LINQ

Question

void Main()
{
    string xml = @"<root>                 
<Page1>
<Key_Head>Name1</Key_Head>
<Key_Title>value1</Key_Title>
</Page1>
<Page1>
<Key_Head>Name2</Key_Head>
<Key_Title>value2</Key_Title>
</Page1>
</root>";
    var doc1 = XDocument.Parse(xml);
    var result = ConvertXmlToDic(doc1.Root);
}

private static List<NameValuePair> ConvertXmlToDic(XElement element)
{
    var result =
        element
            .Elements()
            .Select(e => new
            {
                Name = e.Name.ToString(),
                Value = (e.Descendants().Count() == 0)
                ? e.Value
                : ConvertXmlToDic(e).ToString()
            })
            .ToDictionary(e => e.Name, e => e.Value)
            .Select(e => new List<NameValuePair>()
            {
                new NameValuePair() { Name = e.Key, Value = e.Value }
            });
    return (List<NameValuePair>)result;
}

如何获取 Name1[=14= 的标签值]value1 作为键值。喜欢 (Name1,Value1) 的列表？这是我到目前为止尝试过的。

您可以简化检索 Key_Head 和 Key_Title 的逻辑，如下所示：

private static List<NameValuePair> ConvertXmlToDic(XElement element)
{
    var result = element.Elements()
        .Select(e => new NameValuePair
                {
                    Name = e.Element("Key_Head").Value, 
                    Value = e.Element("Key_Title").Value
                })
        .ToList();
    return result;
}

Output

Name: Name1, Value: value1

Name: name2, Value: value2
