遍历类字段并打印 [英] Iterate through class fields and print them

问题描述

例如，如果我有一个像这样的班级

If I have for example one class like

public class User{
            public int Id { get; set; }
            public int Reputation { get; set; }
            public string DisplayName { get; set; }
            public DateTime LastAccessDate { get; set; }
            public DateTime CreationDate { get; set; }
            public string WebSiteUrl { get; set; }
            public int Views { get; set; }
            public int Age { get; set; }
            public int UpVotes { get; set; }
            public int downVotes { get; set; }
            public string Location { get; set; }
            public string AboutMe { get; set; }
    }

我想动态地遍历这些字段，例如，某种方法将检查传递的对象，并将其返回给调用方其字段.

And I want to iterate through these fields dynamicly, for example to some method which will inspect passed object and it will return to caller its fields.

这可能吗?

推荐答案

它们不是字段，而是属性.您可以使用反射将其列出:

They're not fields, they're properties. You can use reflection to list them:

User user = ...
foreach(PropertyInfo prop in typeof(User).GetProperties())
{
    Console.WriteLine("{0} = {1}", prop.Name, prop.GetValue(user, null));
}
