如何将此 xml 数据的“问题”元素解析为一个名为“问题”的对象，该对象具有一个名为“选项”的字符串数组属性？我知道有很多带有答案的 xml 帖子，但它们都让我感到困惑，我只需要一个适合我的问题的帖子。xml 文件中共有 50 个问题，我想将每个问题元素及其子元素和内容提取到一个问题对象中。我在 Visual Studio 2010 上使用 C#。

您可以使用LINQ to Xml做到这一点：

XDocument xdoc = XDocument.Load(path_to_xml);
var query = xdoc.Descendants("Question")
                .Select(q => new Question()
                {
                    Id = (int)q.Attribute("id"),
                    Content = (string)q.Element("Content"),
                    Options = q.Element("Options")
                               .Elements()
                               .Select(o => (string)o).ToArray()
                });

这将返回IEnumerable<Question>序列，其中 Question 是一个类，如：

public class Question
{
    public int Id { get; set; }
    public string Content { get; set; }
    public string[] Options { get; set; }
}
