Access public variable in other script using string variable

Question

I want to be able to access a variable from one script using a variable in another script. For example, if I have one script that has this variable:

public bool Some_Name;

And in my other script I have this:

private string nameOfThingToGet = "Some_Name";
...
GameObject.Find ("Player").GetComponent <FirstScript> () .nameOfThingToGet = false;

Obviously this wont work, but how would I be able to do something like this?

Before you go down this road, have you considered making FirstScript expose a Dictionary<string, object> instead of using fields? This allows for GameObject.Find ("Player").GetComponent<FirstScript>().dictionary[nameOfThingToGet] = false; — Scott Chamberlain

You can use reflection to achieve it.

var obj = GameObject.Find ("Player").GetComponent<FirstScript>();
FieldInfo myFieldInfo = obj.GetField(nameOfTheThingToGet, 
         BindingFlags.Instance);

I like the reflection solution but since this done in a game engine, Scott's is highly recommended. It's a matter of Dictionary vs Reflection performance.
