Hello,
I am receiving an overload error method, and i am too much of a newbie to figure out what it means. I have a toString all ready declared and it says I can not do that again. Any help will be appreciated.
the assignment was to return the employee names in alphabetical order with a bubble sort.
the first assignment was to return in salary order and I got that one no problem. But the string compare is just not working out for me.
CODE
using System;
namespace BubbleSort2
{
class BubbleSort2
{
static public void Sort(object [] sortArray, CompareOp gtMethod)
{
for (int i=0; i<sortArray.Length; i++)
{
for (int j=i+1; j<sortArray.Length; j++)
{
if (gtMethod(sortArray[j], sortArray[i]))
{
object temp = sortArray[i];
sortArray[i] = sortArray[j];
sortArray[j] = temp;
}
}
}
}
}
class Employee // : object
{
private string name;
private decimal salary;
public Employee(string name, decimal salary)
{
this.name = name;
this.salary = salary;
}
public override string ToString()
{
return string.Format(name + ", {0:C}", salary);
}
public static bool RhsIsGreater(object lhs, object rhs)
{
Employee empLhs = (Employee) lhs;
Employee empRhs = (Employee) rhs;
return (string.Compare()(empRhs.name == empLhs.name)) ? true:false;
}
}
delegate bool CompareOp(object lhs, object rhs);
class bubbleSort
{
static void Main()
{
Employee [] employees =
{ new Employee("Bugs Bunny", 20000),
new Employee("Elmer Fudd", 10000),
new Employee("Daffy Duck", 25000),
new Employee("Wiley E. Coyote", (decimal)1000000.38),
new Employee("Foghorn Leghorn", 23000),
new Employee("RoadRunner", 50000)
};
CompareOp employeeCompareOp = new CompareOp(Employee.RhsIsGreater);
BubbleSort2.Sort(employees, employeeCompareOp);
for (int i=0; i<employees.Length; i++)
Console.WriteLine(employees[i].ToString());
}
}
}
