VS编写个简单小程序

微信公开课小程序热门讨论「VS编写个简单小程序」最新回复-请参考如下代码usingSystem;usingSystem.Collections.Generic;usingSystem.Linq;usingSystem.Text;namespaceSimpleFictory{publicabstractclassOperationBase{privatedouble_num=0;privatedouble_number=0;publicdoubleNum{get{return_num;}set{_num=value;}}publicdoubleNumber{get{return_number;}set{_number=value;}}publicabstractdoubleAmount();}classAdd:OperationBase{publicoverridedoubleAmount(){doubleresult=0;result=Num+Number;returnresult;}}classSub:OperationBase{publicoverridedoubleAmount(){doubleresult=0;result=NumNumber;returnresult;}}classMinus:OperationBase{publicoverridedoubleAmount(){doubleresult=0;result=Num*Number;returnresult;}}classDiv:OperationBase{publicoverridedoubleAmount(){doubleresult=0;if(Number==0)thrownewException(除数不能为0。);result=Num/Number;returnresult;}}publicabstractclassOperationFactory{publicstaticOperationBasecreateOperate(stringoperate){OperationBaseoper=null;switch(operate){case+:oper=newAdd();break;case:oper=newSub();break;case*:oper=newMinus();break;case/:oper=newDiv();break;}returnoper;}}classProgram{staticvoidMain(string[]args){OperationBaseoper;oper=OperationFactory.createOperate(+);//可根据要求更改运算符,仅以加法为例。oper.Num=1;oper.Number=2;doubleresult=oper.Amount();Console.WriteLine(结果是{0},result);Console.ReadKey();}}}
都有类图了，直接找个反向的工具 生成代码算了。 更多有关「VS编写个简单小程序」的疑问请扫码关注微信公开课+小程序！了解更多
