How to AddComponent(variable) easy?

Unity Engine
1

I’m using Unity 5.6

I need use something like AddComponent(variable).
For example:

Now I need something like this:

oj = new GameObject;
forEach(var cp in cpList ) {
   oj.addComponent(cp);
}

But I can’t do that, because AddComponent(string) is deprecated.

I tried

https://stackoverflow.com/questions/1825147/type-gettypenamespace-a-b-classname-returns-null

But in all tests GetType return null.

//        string typeName = "UnityEngine.Transform, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null ";
//        string typeName = "UnityEngine.Transform, Transform, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null ";
//        string typeName = "UnityEngine.Transform, UnityEngine.dll, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null ";
//        string typeName = "Transform, UnityEngine.dll, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null ";
        string typeName = "UnityEngine.Transform, UnityEngine, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null ";
        Type t = Type.GetType(typeName);

There’s a good chance you would be better off taking a step backward and coming at your larger problem from a different angle. Where is this list of components coming from, and why are you creating objects in this way rather than using something like prefabs?
