将存储值类输出到列表

Question

这将从XML文件加载一组值,并将它们放入类中进行存储.我试图弄清楚如何将值输出为列表,以便将它们放入列表框中.

我认为有一种简单的方法,比如.ToList()方法,或者能够通过类中的字符串(没有公共GetEnumerator).我已经能够发现Foreach隐藏了一些复杂性,但没有去做我想做的事情.

我一直在网上搜索没有用(可能没有正确的术语),不幸的是我在工作中留下了我的C#参考书:/

非常感谢指针朝着正确的方向发展,谢谢.

您的类的成员是字段还是属性？无论哪种方式，在从 XML 文件中合并了类的实例后，一点点反射和 Linq 应该允许您枚举类的数据成员。

var fieldDictionary = 
   (from f in typeof(UnitAttributes).GetFields()
    select new {Name = f.Name, Value = (string)(f.GetValue(attributes))})
   .ToDictionary(x=>x.Name, x=>x.Value);

fieldDictionary 现在是 a Dictionary<string, string>（这是一个IEnumerable<KeyValuePair<string, string>>），它应该适合加载到 ListBox 中。

被告知; 反射很慢。对您来说，修改或扩展 UnitAttributes 类来实现 IEnumerable（可能是 Tuple，可能是 KeyValuePair）会更可取。它还允许您按照您想要的顺序枚举类实例的属性，而不是按照它们定义的顺序，或者通过一些其他 FieldInfo/PropertyInfo 数据（例如字段名称）。

另请注意，字段不是属性，反之亦然。如果您的班级混合使用属性和公共字段，我强烈建议您对其中之一进行标准化；否则，您必须使用上述两个 Linq 语句来反映属性列表和字段列表（成本大约是运行时间的两倍），并且它们不可能出现在任何自定义定义中命令。
