Replace Tem with Query

You are using a temporary variable to hold the result of an expression. Extract the expression into a method. Replace all references to the temp with the expression. The new method can then be used in other methods.

Sample:

Before
1        double baseprice = _quantity * _itemPrice;
2        if(baseprice > 1000)
3            return baseprice * 0.95;
4        else
5            return baseprice * 0.98;

After
 1        if(BasePrice() > 1000)
 2            return BasePrice() * 0.95;
 3        else
 4            return BasePrice() * 0.98;
 5
 6
 7        public double BasePrice()
 8        {
 9            return _quantity * _itemPrice;
10        }
