C# 输出不能显示构造函数，但可以显示默认构造函数

下面的代码将显示所有内容。 我可以在默认构造函数上显示。 不幸的是，我无法获得显示员工ID号和付款的任何结果。 我在编写代码时没有遇到任何错误。 因此，我完全不知道

如果在带参数的构造函数中（FEmployeeWorkHour>=0&&FEmployeeWorkHour=0&&FEmployeeWorkHour=1001&&FId 0&&FHrs，则会注释掉支付率。在无参数构造函数中，会计算支付率，但不会调用此构造函数，因为会调用4-args构造函数

员工ID位于等号的错误一侧。您正在使用字段
FEmployeeID
中的任何内容重新分配输入变量
FID
的值

请尝试以下方法：

// Constructor 
public FullTimeEmployee(string FFName, string FLName, double FID, double FHours, double FPRate)
{
    FEmployeeFName = FFName;
    FEmployeeLName = FLName;
    FEmployeeID = FID;
    FEmployeeWorkHour = FHours;
    FEmployeePayRate = FPRate;
}

请注意，构造函数中的所有参数都位于等号的右侧

另一个选项是，如果您想让无参数构造函数从4-（哦，5-）参数构造函数中插入默认值，您可以让4/5-args构造函数在声明末尾使用
this（）
调用无参数构造函数

// Constructor 
public FullTimeEmployee(string FFName, string FLName, double FID, double FHours, double FPRate) 
    : this()
{
    FEmployeeFName = FFName;
    FEmployeeLName = FLName;
    FEmployeeID = FID;
    FEmployeeWorkHour = FHours;
    FEmployeePayRate = FPRate;
}

课堂秩序混乱，但我发现了你的错误。见下文

 //Constructor 
    public FullTimeEmployee(string FFName, string FLName, double FID, double FHours)
    {
        FEmployeeFName = FFName;
        FEmployeeLName = FLName;
        FEmployeeID = FID; // This was backwards in your code.
        FEmployeeWorkHour = FHours;
        RegPay = calcRegPay(); // You need this line and the next one...
        OTPay = CalOTPay(); // to trigger your payment calculations.
    }
