这是我的罚款：

2536 W 55 21

4597 W 75 35
2597 S 35 10
5689 S 40 20
5489 W 55 39
5872 M 60 40
5569 M 55 25
5566 W 80 20
8865 M 59 35
5598 S 65 35
我尝试了什么：
除了我能想到的一切，我不知道如何解决这个问题。我是一个初学者，我的老师是一个坚持形成的人，所以我现在的程序看起来像我的所有格式，我无法改变它。我在Visual 2015中创建了它，因此缩进有点偏差。
Main（）中的UpdateTotals（）出现问题，静态void UpdateTotals（ ）很好。我无法弄清楚我做错了什么。它只是说没有给出的参数对应于'Program.UpdateTotals（）'所需的形式参数'WAge1'。
Here is my fineIn:
1235 W 45 20
2536 W 55 21
5894 W 60 30
4597 W 75 35
2597 S 35 10
5689 S 40 20
5489 W 55 39
5872 M 60 40
5569 M 55 25
5566 W 80 20
8865 M 59 35
5598 S 65 35
What I have tried:
Besides everything I can think of, I'm not sure how to fix this. I am a beginner, and my teacher is a stickler for formation so all of my formatting that the program looks like now, I can't change it. I made it in Visual 2015 so the indenting is off a bit.
It is having a problem with the UpdateTotals() in Main(), the static void UpdateTotals() is fine. I can't figure out what I am doing wrong. It just says "There is no argument given that corresponds to the required formal parameter 'WAge1' of 'Program.UpdateTotals()'."

并且没有人提及UpdateTotals。
因此，代码与您尝试使用的代码完全不同，或者您在很长时间内没有编译并且正在查看旧的错误消息。
在该代码中，您有两种不同的方法，称为CalcAvg，它们具有相同的签名（即它们采用相同的参数 - 无）这意味着系统扫描不知道应该调用哪些参数。
重建你的项目（使用CTRL + SHIFT + B）你应该得到同样的错误。从列表顶部开始，尝试修复它们 - 删除一个CalcAvg方法，然后将参数传递给ParseLineIn，依此类推。
And none of them mentions UpdateTotals.
So either that code is nothing like the code you are trying to work with, or you haven't compiled in a long time and are looking at old error messages.
In that code, you have two different methods called CalcAvg which have identical signatures (i.e. they take the same parameters - none) which means the system scan't tell which it should call.
Rebuild your project (use CTRL+SHIFT+B) and you should get the same errors I do. Start from the top of the list, and try to fix them - remove one of the CalcAvg methods, then pass the parameters to ParseLineIn, and so forth.
Util是一个引用，老师提供，我不知道如何发送。
我修复了CalAvg
The Util is a reference that the teacher provided, I am not sure how to send that.
I fixed CalAvg to
static void CalcAvg()
{
AvgAgeTotal = (WAge1 + WAge2 + WAge3 + WAge4 + WAge5 + WAge6 + WAge7 + WAge8 + WAge9 + WAge10 + WAge11 + WAge12);
AvgAge = AgeAvgTotal / numOfEmployees;
AvgExp = ExpAvgTotal / numOfEmployees;
}
我重建了程序，我将错误复制过来。
I rebuilt the program, I will copy the errors over.
