c# - 在 C# 中从 XML 文件中获取键的值

Question

我有一个具有以下结构的 XML 文件:

<Definitions>
  <Definition Execution="Firstkey" Name="Somevalue"></Definition>
  <Definition Execution="Secondkey" Name="Someothervalue"></Definition>
</Definitions>

如何获取键值(Firstkey、Secondkey)并在我的 .NET 应用程序中使用 C# 记录它们？

谢谢。

使用 Linq to XML 这很简单。

获取 key :

var keys = doc.Descendants("Definition")
              .Select(x => x.Attribute("Execution").Value);
foreach (string key in keys)
{
    Console.WriteLine("Key = {0}", key);
}

获取所有值:

XDocument doc = XDocument.Load("test.xml");
var definitions = doc.Descendants("Definition")
                     .Select(x => new { Execution = x.Attribute("Execution").Value,
                                        Name = x.Attribute("Name").Value });
foreach (var def in definitions)
{
    Console.WriteLine("Execution = {0}, Value = {1}", def.Execution, def.Name);
}

我认为您真正想要的是一个字典，它从一个键(“执行”)映射到一个值(“名称”):

XDocument doc = XDocument.Load("test.xml");
Dictionary<string, string> dict = doc.Descendants("Definition")
                                     .ToDictionary(x => x.Attribute("Execution").Value, 
                                                   x => x.Attribute("Name").Value);
string firstKeyValue = dict["Firstkey"]; //Somevalue
