price = Convert.ToDouble(tcxtprice.Text); //You have to assign the text box value first
price /= diesel;

You could assign some default value for variable "price" while declaring.
EX:double price = 0.00;

1.Remove const Key word before double diesel(If you declare something as constant you cannot change it, thats what the first error is about. it is Expecting a variable)
2 .txtprPrice.text = Convert.ToString(Price); try this to avoid second error(tctPrice.text expects a string value whereas price is not a string, so just convert it).
