How to use a string inside GetComponent to connect others files

I have a string list of characters and I’m trying to get information from another exclusive jin.cs or ken.cs file to the main game.cs file.

How to change this

string character_selected;

  if (character_selected == "jin")
  {
      gameObject.GetComponent<jin>().getinfo;
  }

  if (character_selected == "ken")
  {
      gameObject.GetComponent<ken>().getinfo;
  }

To something like this:

string character_selected;

gameObject.GetComponent<character_selected>().getinfo;

Maybe using .GetType or HingeJoint but it doesn´t work.
