c# - 如何在 C# WPF 应用程序中解析 Xml

Question

UTF 似乎不适用于我的代码。它在第 125 行说错误。

</feed>

我已经尝试指定正在使用的 utf 但似乎不起作用

  var results = XElement.Load("games.xml")
    .Element("content.items")
    .Element("content.head")
    .Element("content.body")
    .Elements("results")
    .Elements("result");

var query = (from result in results
    let homeTeam = result.Element("home-team")
    let awayTeam = result.Element("away-team")
    let lastScorer = result.Descendants("scorers").Elements("scorer").OrderByDescending(p => (int)p.Attribute("time")).FirstOrDefault()
    select new
    {
          HomeTeam = homeTeam.Element("team-name").Value,
          AwayTeam = awayTeam.Element("team-name").Value,

          HomeTeamScore = homeTeam.Element("score").Value,
          AwayTeamScore = awayTeam.Element("score").Value,

          LastScorerName = lastScorer != null ? lastScorer.Element("player-name").Value : string.Empty,
          LastScoreTime = lastScorer != null ? (int?)lastScorer.Attribute("time") : null
    }).ToList();

使用 Linq To XML 让您的生活更轻松.

下面的代码可以正常工作，并且比使用低级 XmlReader 更具可读性。

假设 xml 存储在名为 games.xml 的文件中。

    var results = XElement.Load("games.xml")
        .Element("content.items")
        .Element("content.head")
        .Element("content.body")
        .Elements("results")
        .Elements("result");

    var query = (from result in results
        let homeTeam = result.Element("home-team")
        let awayTeam = result.Element("away-team")
        let lastScorer = result.Descendants("scorers").Elements("scorer").OrderByDescending(p => (int)p.Attribute("time")).FirstOrDefault()
        select new
        {
              HomeTeam = homeTeam.Element("team-name").Value,
              AwayTeam = awayTeam.Element("team-name").Value,

              HomeTeamScore = homeTeam.Element("score").Value,
              AwayTeamScore = awayTeam.Element("score").Value,

              LastScorerName = lastScorer != null ? lastScorer.Element("player-name").Value : string.Empty,
              LastScoreTime = lastScorer != null ? (int?)lastScorer.Attribute("time") : null
        }).ToList();
