Question

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。

Answer 1

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＆＃39; totlalDuesOwedIn＆＃39;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＆＃34; totalDuesOwedIn＆＃34;。

错误：CS0029无法隐式转换类型＆＃39;字符串＆＃39;到十进制＆＃39;

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。

Answer 2

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();

    }
