问题描述
大家好,
我正在努力完成我的课程工作,并坚持不解决问题。
我有三个班:汽车,小巴和卡车。
我希望这辆车成为我的基地和小巴,卡车继承了汽车类的财产。
我不断收到错误消息:
''xxxx.Car''不包含带0参数的构造函数。这适用于小巴和卡车。
这是我的车类:
展开 | 选择 | Wrap | 行号
解决方案
您的汽车类名为FrmCar:
展开 | 选择 | Wrap | 行号
FrmCar是我创建的表单/添加新车。
Car.cs是具有特殊性的汽车类别。
我这样做是错误的吗?
感谢您的回复,
迈克
ps我使用VS如果有所作为。
再次
我发错了代码。这不是car.cs你是对的是FrmCar:)
这是我的汽车类代码:
展开 < span class =codeDivider> | 选择 | Wrap | Line编号跨度>
Hi there all,
Im curently working on my course work and got stuck on of the questions.
I have three classes : car, minibus and truck.
I want the car to be my base and minibus, truck to inherit the property of the car class.
I keep getting an error message :
''xxxx.Car'' does not contain the constructor that takes 0 arguments. This is for both minibus and truck.
Here is my car class :

Expand|Select|Wrap|Line Numbers
FrmCar is my form in which i create/add new cars.
Car.cs is the car class with properites ect.
Am I doing it the wrong way?
Thanks for you reply,
Mike
p.s Im using VS if that makes a difference.
