c＃将纳税人类别数据成员设置为等于另一种方法
|
我对C＃还是很陌生，对如何设置数据成员然后使用另一种方法计算税收感到困惑。这是程序的这一部分应该做的：
\“如果用户选择默认的默认值，则将使用默认构造函数实例化费率对象，并将Taxtaxer类数据成员的税额设置为等于调用费率对象CalculateTax方法返回的值。
-我有一个switch语句，如果他们选择\'D \'，则要求默认的构造函数，我不确定如何将纳税人类数据设置为默认值，我不确定CalculateTax方法是否正确。
然后如果他们选择\'O \'，则执行相同类型的操作
这是我到目前为止的内容：
using System;
interface Icomparable
{
int CompareTo(Object o);
}
class rates
{
public double Limit{get;}
public double LowRate{get;}
public double HighRate{get;}
private rates()
{
Limit = 30000;
LowRate = 0.15;
HighRate = 0.28;
}
public rates(double Limit; double LowRate; double HighRate;)
{
Console.Write(\"Enter dollar limit: \");
Limit = Convert.ToDouble(Console.ReadLine());
Console.Write(\"Enter the low rate: \");
LowRate = Convert.ToDouble(Console.ReadLine());
Console.Write(\"Enter the high rate: \");
HighRate = Convert.ToDouble(Console.ReadLine());
}
public CalculateTax()
{
if(Income < Limit)
{TaxOwed = (Income * LowRate)}
else
{TaxOwed = (Income * HighRate)}
}
}
public class taxpayer : IComparable
{
public string SSN{get; set;}
public double Income{get; set;}
public double TaxOwed{get;}
int IComparable.CompareTo(Object o)
{
int returnVal;
taxpayer temp = (taxpayer)o;
if(this.TaxOwed > temp.TaxOwed)
returnVal = 1;
else
if(this.TaxOwed < temp.TaxOwed)
returnVal = -1;
else
returnVal = 0;
return returnVal;
}
public getRates()
{
double Limit;
double LowRate;
double HighRate;
Console.WriteLine(\"Do you want default values(enter D) or enter your own (enter O)?\");
entry = Convert.ToChar(Console.ReadLine());
switch (entry) //set switch
{
case\'D\':
rates();
break;
case\'O\':
rates(double Limit; double LowRate; double HighRate;)
break;
default:
Console.WriteLine(\"Invalid input\");
goto getRates();
}
}
}

class Rates { public double Limit{get;} public double LowRate{get;} public double HighRate{get;} static readonly Rates default = new Rates(30000,0.15,0.28); static readonly Rates govna = new Rates(300000,0.1,0.2); static readonly Rates priest = new Rates(300,0.05,0.07); public static Rates createRates() { double Limit; double LowRate; double HighRate; Console.Write(\"Enter dollar limit: \"); Limit = Convert.ToDouble(Console.ReadLine()); Console.Write(\"Enter the low rate: \"); LowRate = Convert.ToDouble(Console.ReadLine()); Console.Write(\"Enter the high rate: \"); HighRate = Convert.ToDouble(Console.ReadLine()); return new Rates( Limit, LowRate, HighRate ); } private Rates(double limit; double lowRate; double highRate;) { Limit = limit; LowRate = lowRate; HighRate = highRate; } public double CalculateTax( double Income) { if(Income < Limit) {return (Income * LowRate)} else {return (Income * HighRate)} } }while( null == ratesResult ){ Console.WriteLine(\"Do you want default values(enter D) or enter your own (enter O)?\"); entry = Convert.ToChar(Console.ReadLine()); switch (entry) //set switch { case\'D\': ratesResult = Rates.default; break; case\'O\': ratesResult = Rates.createRates(); break; default: Console.WriteLine(\"Invalid input\"); } }呸溉
public double Limit{get;} public double LowRate{get;} public double HighRate{get;}至现在你的代码看起来像public rates(bool dummy) //Note that dummy is not used in this function. It just distinguishes rates() from rates(bool) { Console.Write(\"Enter dollar limit: \"); Limit = Convert.ToDouble(Console.ReadLine()); Console.Write(\"Enter the low rate: \"); LowRate = Convert.ToDouble(Console.ReadLine()); Console.Write(\"Enter the high rate: \"); HighRate = Convert.ToDouble(Console.ReadLine()); }switch (entry) //set switch { case\'D\': rates(); break; case\'O\': rates(true) break; default: Console.WriteLine(\"Invalid input\"); goto getRates(); }
