所以我对编程非常陌生,我试图从我的书中编写一个程序。
这是作业:
编写一个程序,让这个学校俱乐部能够确定他们的直板销售的一些事情。他们可以输入诸如他们有多少箱子,每箱的成本,每个糖果棒的成本等等。然后程序使用方法将返回一些计算,如他们的毛利润,扣除%由于他们的学生政府,并给予净利润。

答案 0 :(得分:2)
错误CS0116命名空间不能直接包含字段或方法等成员
您有很多在类外声明的方法,这是不允许的。将方法移动到标记类范围的括号内。
错误:CS0103名称' totlalDuesOwedIn'在当前上下文中不存在
方法totlalDuesOwedIn
不存在。这可能是一个错字,你打算键入" totalDuesOwedIn"。
错误:CS0029无法隐式转换类型'字符串'到十进制'
您的方法返回string
类型的值,但您尝试将值存储在decimal
类型的变量中。这两种类型不能与其他类型隐式兼容,但您可以使用decimal.Parse(stringVal)
之类的转换方法来尝试转换它们。
答案 1 :(得分:1)
有很多错误,但要开始
由于声明了totalAmountCases的位置
,因此无法编写public static decimal CalctotalAmountCandyBars(decimal candyBarsPerCase)
{
return totalAmountCases * candyBarsPerCase;
//returns the total number of candy bars
}
将totalAmountCases声明移出main - :
class GranolaBarSalesProject
{
const decimal sgaDues = .010m;
decimal totalAmountCases;
static void Main(string[] args)
{
//Capture total number of candy bars//
totalAmountCases = GetCases();
}
