Rigidbody.AddForce not being detected

Question

When I am inputting lines to add a force in both 2d and 3d, addforce is said not to exist in the directories and when it comes to running. I keep getting the CS0120 Error. I reinstalled the program with hopes of it being just a glitch in the installation but it still appears to be missing. Edit:

    void Update () {
         if(Input.GetKey(KeyCode.D)){
             Rigidbody2D.AddForce (Vector2.right);
         }
 }

I just tried it with a basic line added the component to a sprite to see if it would work but for some reason it just doesn't

Rigidbody is the class. You want the instance of the class. And Capitalisation matters: AddForce not addforce.

 GetComponent<Rigidbody2D>().AddForce (Vector2.right);

Thanks for the suggestion but it doesn't seem to work either, I get the same error and message. The capitalization is as I've written it so it shouldn't have been a problem either.

Nevermind, I just got your method to work, thanks, it took some fanagling as when I used my original code with a lowercase r for rigid body, unity restructured it since it was thought to be in an older format and it spat out this which worked

 void Update () {
         if (Input.GetKey (KeyCode.W)) {
             GetComponent<Rigidbody2D>().AddForce = Vector2.up * speed;
                 }

So Thanks For the Help!

Well addforce won't be found because it's AddForce- case sensitive. Also, you don't seem to be giving a value to the amount. Have you tried

 Rigidbody2D.AddForce (Vector2.right * someVar);

?

I type AddForce as given since a lot of the problems with it I saw when researching solutions were because of it. I type it in correctly and I've tried different variables but still nothing.
