c# - checking the states in unity -

i wanted animate object in unity. first, want check player states. have use enum naming states. here code checking state:

switch(playerstatecontroller.playerstates)     {     case playerstatecontroller.playerstates.idle:         break;     case playerstatecontroller.playerstates.left:         transform.translate(new vector3(-1.5f * time.deltatime, 0.0f, 0.0f));         break;     case playerstatecontroller.playerstates.right:         transform.translate(new vector3(1.5f * time.deltatime, 0.0f,                                        0.0f));         break;     } 

but have error:

expression denotes 'type', 'variable', 'value' or 'method group' expected

public class anyclass {     public enum playerstate {         idle,         left,         right     } } 

-

public class anyotherclass {     void dostuff(playerstate state) {         switch (state) {         case playerstate.idle:             break;         case playerstate.left:             transform.translate(new vector3(-1.5f * time.deltatime, 0.0f, 0.0f));             break;         case playerstate.right:             transform.translate(new vector3(1.5f * time.deltatime, .0f, 0.0f));             break;         }     }
