Question How can I check if Animator ended playing specific State animation?

This way it's getting inside all the time while the animation state is playing :

Code (csharp):

1.  
2.     void Update()
3.         {
4.             if (this.animator.GetCurrentAnimatorStateInfo(0).IsName("Stand Up"))
5.             {
6.                 string tt = "";
7.             }
8.         }
9.  

So I tried to add ! to check if it false :

Code (csharp):

1.  
2.     void Update()
3.         {
4.             if (!this.animator.GetCurrentAnimatorStateInfo(0).IsName("Stand Up"))
5.             {
6.                 string tt = "";
7.             }
8.         }
9.  

but this way it's never getting inside even if the state animation finished playing.

I have one Base Layer in the animator controller.

 

If the first one works, the second one will too so you must be doing something else wrong.
