Question How to check if animation is playing

I have two types of animation - looped and urgent not looped.
the looped one is played during control, and the urgent one is played when, for example, they hit, fell, in general, this animation interrupts any looped one, while the looped one should not be performed until this urgent one ends.

Question - how to check when it ended? (to further check whether it is possible to play a looped one)

I came across a similar example on the web.

Code (CSharp):

1. private bool GetPlayAnimation(){
2.     bool b = false;
3.     if(animator.GetCurrentAnimatorStateInfo(AnimationLayer).IsName(AnimationName)){
4.     // if(animator.GetCurrentAnimatorStateInfo(AnimationLayer).IsName("LayerName." + AnimationName)){
5.         b = true;
6.         }
7.     return b;
8.     }

but it always gives me a false.
