How can I convert string value to object property name
提问by LaRae White
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 coverin such a way:
这是我第一次在 C#/.NET 中做这样的事情，有点让我想起在 JavaScript 中使用 eval() 函数或动态脚本和生成 HTML 可以轻松完成的事情。我有一个取自用户输入的字符串，比如说string input = "foo". 现在我想使用该值"foo"作为我拥有的对象的属性名称，cover例如：
string input = "foo";
//magic to convert string value to be used
//as a object property name goes here maybe...
var success = cover.foo;
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.
在 C# 中有一种方法可以做这样的事情吗？可能使用反射？我试过了，但我总是返回一个不能真正解决我的问题的对象。

Reflection is the right tool:
反射是正确的工具：
PropertyInfo pinfo = typeof(YourType).GetProperty("YourProperty");
object value = pinfo.GetValue(YourInstantiatedObject, null);
