如何将字符串值转换为对象属性名称 [英] How can I convert string value to object property name

问题描述

这是我第一次必须在C＃/。NET中执行此类操作，这使我想起了可以使用eval（）函数或动态编写脚本并生成HTML在JavaScript中轻松完成的操作。我有一个来自用户输入的字符串，可以说 string input = foo 。现在，我想使用值 foo 作为我拥有的对象的属性名称，例如 cover 这样：

this is my first time having to do something like this in C#/.NET and somewhat reminds me of what can easily be done in JavaScript using the eval() function or dynamically scripting and generating HTML. I have a string that is taken from user input, lets say string input = "foo". Now I would like to use the value "foo" as the name of the property for an object I have, say cover in such a way:

string input = "foo";
//magic to convert string value to be used
//as a object property name goes here maybe...
var success = cover.foo;

在C＃中是否可以做这样的事情？可能使用反射？我已经尝试过，但是我总是会得到一个不能真正解决我问题的对象。

Is there a way in C# that I can do such a thing? Possibly using reflection? I've tried but I always am returned with an object that doesn't really solve my problem.

推荐答案

反射是正确的工具：

PropertyInfo pinfo = typeof(YourType).GetProperty("YourProperty");
object value = pinfo.GetValue(YourInstantiatedObject, null);
