I'm trying to get away from having to hard code in the names of objects I want my code to use.

For example, I'm use to do it this way:

    TextAsset test = new TextAsset();
    test = (TextAsset)Resources.Load("test.txt", typeof(TextAsset));

What I want to know, is there a way to have so that when I drag my test.txt file onto my object in Unity, my code automatically gets the name of that object?

I'm wanting to do this so once I write the code, I don't need to back in and change it should I wish re-use it.
