我必须创建一个适当的GUI来输入至少10名员工的信息。对于每个员工，我必须输入以下信息。员工ID，员工名字，员工姓氏和年薪。此外，我必须检查输入数据的正确性。此外，我需要创建一个单独的类 EMPLOYEE ，其中包含员工信息：员工ID，名字，姓氏和年薪。该类应具有构造函数属性和方法。所有员工信息必须存储在类型员工的数组中。在阅读表单GUI后，有关特定员工的信息，还会使用相关的构造函数创建类employee（对象的元素）的对象。尽管有一个以上年薪最低的员工，但用户希望能够找到年薪最低的员工。并显示有关它们的信息。应为用户提供适当的GUI以显示所需信息。 我需要确保在我的程序中包含处理异常的适当代码以及适当的方法。
这是班级员工：

用户如何找到年薪最低的员工。我必须确保可以有多个年薪最低的员工并显示有关他们的信息。为用户提供适当的GUI（例如消息框）以显示所需信息，包括处理异常的适当代码，并在适当情况下使用方法？
答案 0 :(得分：0)
您需要让您的类Employee实现 IComparable 接口，然后将这些对象与工资进行比较，并在另一个类中对数组进行排序......
public class Employee :IComparable<Employee>
{
private int employeeID;
private string fullName;
private string lastName;
private double salary;
public int CompareTo(Employee other)
{
return salary.CompareTo(other.salary);
}
}
private void Find()
{
Array.Sort(employee); // after this Employee is sorted
employee[0];
or
employee[9];
}

这将列出最低工资的员工
employee.Add(new Employee(17434, "Stephen", "Rad", 9000.00));
employee.Add(new Employee(17435, "Jesse", "Harris", 800.00));
employee.Add(new Employee(17436, "jonatan", "Morris", 9500.00));
var c = employee.OrderBy(i => i.salary).ToList();
var e = employee.Where(i => Math.Abs(i.salary - c[0].salary) < 1).ToList();

稍微修改了你的代码
class Employee
{
private int employeeID;
private string fullName;
private string lastName;
private double salary;
public double Salary
{
get
{
return salary;
}
set
{
salary = value;
}
}
//public Employee()
//{
// employeeID = 0;
// fullName = "";
// lastName = "";
// salary = 0.0;
//}
//public Employee(int empIDValue, string fullNameVal, string lastNameVal)
//{
// employeeID = empIDValue;
// fullName = fullNameVal;
// lastName = lastNameVal;
// salary = 0.0;
//}
public Employee(int empIDValue, string fullNameVal, string lastNameVal, double salaryValue)
{
employeeID = empIDValue;
fullName = fullNameVal;
lastName = lastNameVal;
salary = salaryValue;
}
public int EmployeeIDNum
{
get
{
return employeeID;
}
set
{
employeeID = value;
}
}
public string FullName
{
get
{
return fullName;
}
set
{
fullName = value;
}
}
public int Getinfo
{
get
{
return employeeID;
}
set
{
employeeID = value;
}
}
public string employeeInformationToString()
{
// employeeID = Convert.ToInt32(this.textBox1.Text);
return (Convert.ToString(employeeID) + " " + fullName + " " + lastName + " " + Convert.ToString(salary));
}
}
并获取列表中的最小值
var minEmpSalarylist = employee.Where(x => x.Salary == employee.Min(y => y.Salary)).ToList();
如果存在默认构造函数，则所有minEmpSalarylist都会使用默认构造函数进行初始化。
和
employee[0] = new Employee();
将其更改为
employee[0] = new Employee(17433, "XXX", "YYY", 8000.00);
