我有一个计算工资单税的程序。我需要一个for循环来写出姓氏，名字，部门，费率，小时，收入，fica，fedtax，statetax和netpay。当我运行程序时，我没有抛出任何错误，似乎无法找到为什么我的输出只显示姓氏。有两个.txt个文件，一个是输出空白，另一个是下面列出的。

您应该更改ParseLineIn方法以使用从调用方传递的索引。实际上，当您将i设置为零时，您始终设置相同的索引
static void ParseLineIn(string lineIn, uint i)
{
string[] words = new string[5];
lineIn = lineIn.Trim();
while (Regex.IsMatch(lineIn, "[ ]{2}"))
lineIn = lineIn.Replace(" ", " ");
words = lineIn.Split(' ');
lastNameArray[i] = words[0];
// i = 0;
// No loop needed, you are reading one line of data and setting
// the appropriate index in the arrays
// while (i <= numOfEmployees)
//{
lastNameArray[i] = words[0];
firstNameArray[i] = words[1];
deptArray[i] = uint.Parse(words[2]);
rateArray[i] = double.Parse(words[3]);
hoursArray[i] = double.Parse(words[4]);
// i++;
//}
}
另请注意，您的Total方法在此行中有错误
for (i = 1; i <= numOfEmployees; i++) ;
删除for循环末尾的分号，以允许执行该行的总和。
说这一切，我真的建议你放弃这种数组方法并构建一个代表你的数据的正确类，并在这些数据的List中收集信息。实际上你的代码只允许50行的文件，请记住NET中的数组从索引零开始。
