按索引访问属性 [英] Access property by Index

问题描述

我需要通过索引或类似的东西来访问一个属性.这个已经回答的问题中解释了原因.该答案使用 Linq，我更喜欢没有这种依赖性的东西.我无法控制课程.

I need to access a property by an index or something similar. The reason why is explained in this already answered question. That answer uses Linq and I prefer something without that dependency. I have no control over the class.

public class myClass
{
    private string s = "some string";
    public string S
    {
        get { return s; }
    }
}

class Program
{
    static void Main(string[] args)
    {
        myClass c = new myClass();
        // I would like something similar
        // or same functionality
        string s = c["S"];
    }
}

推荐答案

使用(编辑 - 根据评论):

use (EDIT - as per comment):

string s = c.GetType().GetProperty ("S").GetGetMethod().Invoke (c, null).ToString();

它为您提供实例 c 的名为 S 的(公共)属性的值，而不管 c 的类型如何，并且不会根本不使用 LINQ，尽管我必须承认我不明白为什么 LINQ 应该是一个问题...

It gives you the value of the (public) property named S of the the instance c regardless of the type of c and doesn't use LINQ at all although I must admit that I don't see why LINQ should be a problem...
