我已经尝试过if，else if，else语句，我已经尝试过嵌套if语句。我尝试使用变量代替if语句。除团队负责人部分外，所有功能均正常运行，“ TrainHours”存在问题，并且重复使用该代码，更正后的“ Hours”存在问题，最新的更正是“ GetPay（）” ”。
我已经尝试了可以在网上以及在教科书中找到的各种方法，但是无论我得到什么
“引发了'System.StackOverflowException'。'“
-OR-
“'未知模块异常中的未知错误'”

问题出在TeamLeader::getData()
getTBonus()调用getTPay()，后者再次调用getTBonus()导致无限循环，这将引发StackOverflowException。
您可以尝试在这些方法中使用if...else if，而不仅仅是if。
public decimal getTBonus()
{
decimal tBonus = 0;
if (TrainHours <= 0 && Hours <= 0)
{ tBonus = 0; }
else if (TrainHours >= (Hours * .15m))
{ tBonus = getTPay() * .15m; }
else if (TrainHours >= (Hours * .1m))
{ tBonus = getTPay() * .125m; }
else if (TrainHours >= (Hours * .08m))
{ tBonus = getTPay() * .05m; }
else
{ tBonus = getTPay() * .025m; }
return tBonus;
}
public decimal getTPay()
{
decimal paid = 0;
if (Hours <= 0)
{ paid = 0; }
else if (Hours > 40)
{ paid = (HourlyRate * 40) + Overtime() + getTBonus(); }
else
{ paid = (Hours * HourlyRate) + getTBonus(); }
return paid;
}
答案 1 :(得分：0)
我能够通过从getPay（）方法中删除getBonus（）解决问题。完成之后，我添加了一个新变量，将它们添加到getData（）方法中。这工作了。现在，我只需要弄清楚为什么我的TrainHours不会填充。谢谢您，这对指导我给出答案很有帮助。
十进制每周支付= getTBonus（）+ getTPay（）;
line + =“每周工资：\ t” + weeklyPay.ToString（“ C”）;
