LINQ to XML,ORM还是"完全不同"的东西？

我需要一个ORM吗？

不.您没有映射到关系源,因此对象关系映射器无济于事.

使用Linq to Xml完成它.

public CustomClass TranslateME(XElement source)
{
  CustomClass result = new CustomClass();
  result.Words = (int) source.Attribute("Words");
  result.Score = (int) source.Attribute("Score");

  XAttribute highScore = source.Attribute("HighScore");
  result.HighScore = (highScore == null) ? 0 : (int) highScore;

  result.NMs = source
    .Elements("NM")
    .Select(x => x.Value)
    .ToList();

  result.IE = source
    .Element("IE").Value;

  result.SubEntries = source
    .Elements("M1")
    .Select(x => TranslateM1(x))
    .ToList();

  return result;
}
