问为什么我在firebase android xamarin中弄错了当前用户

EN

 //get the current user like that

var currentuser =FirebaseAuth.Instance.CurrentUser;

 //check is user not null (in other words if user signed in)

  if(currentuser != null){

   //this means user is signed in

     //get user uid
    var uid= currentuser.Uid;

     //get user email
    var email= currnetuser.Email;

  }

auth.SignInWithEmailAndPassword(email,password)
                .AddOnCompleteListener(this,this);
StartActivity(intent);  // incorrect

 auth.SignInWithEmailAndPassword(email,password)
                        .AddOnCompleteListener(this,this);
    ...
    public void OnComplete(Task task)
   {
                if(task.IsSuccessful){

                    StartActivity(intent);
                    Finish();
                }
   }

FirebaseUser currentUser = _auth.CurrentUser;
