请在foreach循环中有一个for循环，在for循环中，每个雇员的工资单中都有一个计算，当我返回输出时，它仅返回第一个，请问如何返回所有员工一次？
这是我的下面的代码
var templateId = (from o in db.PayrollTemplate
select new
{
o.TemplateId,
o.GradeId
}).ToList();
foreach (var items in templateId)
{
var empToRun = (from x in db.Employee
join y in db.SalaryInfo on x.Id equals y.EmployeeId
where x.GradeLevel == items.GradeId && x.Id == y.EmployeeId
select new
{
Id = x.Id
}).ToList();
var empToCount = (from x in db.Employee
join y in db.SalaryInfo on x.Id equals y.EmployeeId
where x.GradeLevel == items.GradeId && x.Id == y.EmployeeId
select x).Count();
for (int i = -1; i <= empToCount;)
{
i++;
decimal payE = 0;
var empId = empToRun[i].Id;
var getGross = (from o in db.Employee
join a in db.SalaryInfo on o.Id equals a.EmployeeId
where o.Id == empId
select new
{
GrossPay = a.GrossPay
}).FirstOrDefault();
var percent = 20 * getGross.GrossPay;
var twentyPercent = percent / 100;
var cra = 200000 + twentyPercent;
var taxAbleIncome = getGross.GrossPay - cra;
if (taxAbleIncome >= 300000)
{
var sevenPercent = (7 * 300000) / 100;
payE = sevenPercent;
taxAbleIncome = taxAbleIncome - 300000;
}
else
{
var Yearly = "Year PayE: " + payE;
var pmonth = payE / 12;
var Monthly = "Monthly PayE: " + Math.Round(pmonth, 2);
return Json(Yearly + " " + Monthly);
}
if (taxAbleIncome >= 300000)
{
var elevenPercent = (11 * 300000) / 100;
payE = payE + elevenPercent;
taxAbleIncome = taxAbleIncome - 300000;
}
else
{
var elevenPercent = (11 * taxAbleIncome) / 100;
payE = payE + (decimal)elevenPercent;
var Yearly = "Year PayE: " + payE;
var pmonth = payE / 12;
var Monthly = "Monthly PayE: " + Math.Round(pmonth, 2);
return Json(Yearly + " " + Monthly);
}
if (taxAbleIncome >= 500000)
{
var fifteenPercent = (15 * 500000) / 100;
payE = payE + fifteenPercent;
taxAbleIncome = taxAbleIncome - 500000;
}
else
{
var fifteenPercent = (15 * taxAbleIncome) / 100;
payE = payE + (decimal)fifteenPercent;
var Yearly = "Year PayE: " + payE;
var pmonth = payE / 12;
var Monthly = "Monthly PayE: " + Math.Round(pmonth, 2);
return Json(Yearly + " " + Monthly);
}
if (taxAbleIncome >= 500000)
{
var nineteenPercent = (19 * 500000) / 100;
payE = payE + nineteenPercent;
taxAbleIncome = taxAbleIncome - 500000;
}
else
{
var nineteenPercent = (19 * taxAbleIncome) / 100;
payE = payE + (decimal)nineteenPercent;
var Yearly = "Year PayE: " + payE;
var pmonth = payE / 12;
var Monthly = "Monthly PayE: " + Math.Round(pmonth, 2);
return Json(Yearly + " " + Monthly);
}
if (taxAbleIncome > 1600000)
{
var twentyonePercent = (21 * 1600000) / 100;
payE = payE + twentyonePercent;
taxAbleIncome = taxAbleIncome - 1600000;
}
else
{
var twentyonePercent = (21 * 1600000) / 100;
payE = payE + twentyonePercent;
var Yearly = "Year PayE: " + payE;
var pmonth = payE / 12;
var Monthly = "Monthly PayE: " + Math.Round(pmonth, 2);
return Json(Yearly + " " + Monthly);
}
if (taxAbleIncome > 3200000)
{
var twentyfourPercent = (24 * 3200000) / 100;
payE = payE + twentyfourPercent;
}
else
{
var twentyfourPercent = (21 * taxAbleIncome) / 100;
payE = payE + (decimal)twentyfourPercent;
var Yearly = "Year PayE: " + payE;
var pmonth = payE / 12;
var Monthly = "Monthly PayE: " + Math.Round(pmonth, 2);
return Json(Yearly + " " + Monthly);
}
var Year = "Year PayE: " + payE;
var Month = "Monthly PayE: " + payE / 12;
return Json(Year + " " + Month);
}
}
上面的代码仅针对第一位员工返回，如果我将return语句放在循环外，我不知道如何获取内部信息，那么有没有办法可以为每位员工执行工资计算，那么一次返回所有输出？

在代码顶部添加一个空列表，并在for循环中填充要返回的值：
var templateId = (from o in db.PayrollTemplate
select new
{
o.TemplateId,
o.GradeId
}).ToList();
List<JsonResult> list = new List<JsonResult>();
foreach (var items in templateId)

var empToRun = (from x in db.Employee
join y in db.SalaryInfo on x.Id equals y.EmployeeId
where x.GradeLevel == items.GradeId && x.Id == y.EmployeeId
select new
{
Id = x.Id
}).ToList();
var empToCount = (from x in db.Employee
join y in db.SalaryInfo on x.Id equals y.EmployeeId
where x.GradeLevel == items.GradeId && x.Id == y.EmployeeId
select x).Count();
for (int i = 0; i <= empToCount;i++)
{
decimal payE = 0;
var empId = empToRun[i].Id;
var getGross = (from o in db.Employee
join a in db.SalaryInfo on o.Id equals a.EmployeeId
where o.Id == empId
select new
{

}).FirstOrDefault();
var percent = 20 * getGross.GrossPay;
var twentyPercent = percent / 100;

我假设您是编程的新手，我对代码进行了更改，可以在其中编写收益回报。
我已经注释了一个代码，您可以在其中再次查询计数，但是该查询与之前的代码类似，您可以查看是否正在循环，这是我在做什么。
我不建议这样的代码包含很多if..else，但味道很差，但这是您可以弄清楚的。
