Mình có đoạn Code bên dưới, mình thấy code lặp lại khá nhiều nhưng chưa biết cách xử lý như nào cho ổn, mọi người tư vấn mình với.

if (typeof(IBlock) == BlockCurrent.GetType())
{
                var iBlock = BlockCurrent as IBlock;
                CurrentRationRotation += 90;
                DoubleAnimation rotationLeftIconMenunAnimation = new DoubleAnimation(CurrentRationRotation, TimeSpan.FromMilliseconds(200));
                iBlock.AssetsRotation.BeginAnimation(RotateTransform.AngleProperty, rotationLeftIconMenunAnimation);
}
else if (typeof(LBlock) == BlockCurrent.GetType())
{
                var lBlock = BlockCurrent as LBlock;
                CurrentRationRotation += 90;
                DoubleAnimation rotationLeftIconMenunAnimation = new DoubleAnimation(CurrentRationRotation, TimeSpan.FromMilliseconds(200));
                lBlock.AssetsRotation.BeginAnimation(RotateTransform.AngleProperty, rotationLeftIconMenunAnimation);
}
else if (typeof(ZBlock) == BlockCurrent.GetType())
{
                var zBlock = BlockCurrent as ZBlock;
                CurrentRationRotation += 90;
                DoubleAnimation rotationLeftIconMenunAnimation = new DoubleAnimation(CurrentRationRotation, TimeSpan.FromMilliseconds(200));
                zBlock.AssetsRotation.BeginAnimation(RotateTransform.AngleProperty, rotationLeftIconMenunAnimation);
}            
else if (typeof(TBlock) == BlockCurrent.GetType())
{
                var tBlock = BlockCurrent as TBlock;
                CurrentRationRotation += 90;
                DoubleAnimation rotationLeftIconMenunAnimation = new DoubleAnimation(CurrentRationRotation, TimeSpan.FromMilliseconds(200));
                tBlock.AssetsRotation.BeginAnimation(RotateTransform.AngleProperty, rotationLeftIconMenunAnimation);
}
