c# - Unity: detect animation's end

I need a way to detect if animation's clip finished playing and then execute a certain code. Here's some script, that I wrote (called in Update):

    if (Input.GetButtonDown ("Fire1") && pc_atttacking == false && PlayerStats.staminaCurrent != 0) {
        pc_atttacking = true;
        pc_anim.SetBool("attack", true);
    }


    if (pc_anim.GetCurrentAnimatorStateInfo (0).IsName ("attack")) {
        pc_atttacking = false;
        pc_anim.SetBool("attack", false);
    }

But it doesn't work as I want; it executes second code too early - when "attack" animation is at slightly more than half of playing position. I want to execute it when "attack" animation is at last frame.
