错误 CS0051(不一致的可访问性:参数类型 'Job' 的可访问性低于方法 'AddJobs.TotalPay(Job)') [英] Error CS0051 (Inconsistent accessibility: parameter type 'Job' is less accessible than method 'AddJobs.TotalPay(Job)')

问题描述

我通过省略 totalFee 字段成功编译并运行了下面的源代码.如何将 totalFee 写入该程序，以便准确计算每项工作的总费用(费率 * 时间)?下面，你会看到我尝试使用一种方法；这产生了错误 CS0051(不一致的可访问性:参数类型 'Job' 比方法 'AddJobs.TotalPay(Job)' 更难访问).

I compiled and ran the source code below successfully by omitting the totalFee field. How do I write totalFee into this program so that it will accurately calculate the total fee for each job (rate * time)? Below, you'll see I tried using a method; which generated the error CS0051 (Inconsistent accessibility: parameter type 'Job' is less accessible than method 'AddJobs.TotalPay(Job)').

此源代码是对以下作业的响应:

This source code is in response to the following assignment:

为 Harold 的家庭服务设计一个 Job 类.该类包含四个数据字段——Job描述(例如，清洗窗户")，完成工作的时间(以小时为单位)(对于例如，3.5)，为作业收取的每小时费率(例如，25.00 美元)和总费用工作(每小时费率乘以小时数).包括获取和设置每个字段的属性，除了总费用 - 该字段将是只读的，并且每次都会计算其值小时费或小时数已设置. 重载 + 运算符，以便两个作业可以添加.两个 Job 的总和是一个包含两个 Job 描述的新 Job原始作业(由和"连接)，原始作业的时间总和，以及原始作业的平均每小时费率.编写一个 Main() 函数来演示所有方法都能正常工作.将文件另存为 DemoJobs.cs."

"Design a Job class for Harold’s Home Services. The class contains four data fields—Job description (for example, "wash windows"), time in hours to complete the Job (for example, 3.5), per-hour rate charged for the Job (for example, $25.00), and total fee for the Job (hourly rate times hours). Include properties to get and set each field except the total fee—that field will be read-only, and its value is calculated each time either the hourly fee or the number of hours is set. Overload the + operator so that two Jobs can be added. The sum of two Jobs is a new Job containing the descriptions of both original Jobs ( joined by "and"), the sum of the time in hours for the original Jobs, and the average of the hourly rate for the original Jobs. Write a Main()function that demonstrates all the methods work correctly. Save the file as DemoJobs.cs."

这里是源代码:

using System;

public class AddJobs
{
  private double totalFee;

  public AddJobs(double totalFee)
  {
     TotalFee = totalFee;
  }

  public static void Main()
  {
     Job job1 = new Job("washing windows", 5.00, 25.00);
     Job job2 = new Job("walking a dog", 3.00, 11.00);
     Job job3;
     job3 = job1 + job2;

     Console.WriteLine("The first job's description: {0} 
Total time needed to complete the job: {1} hours 
Hourly fee: {2} per hour", job1.Description, job1.Time, job1.Rate.ToString("C"));
     TotalPay(job1);

     Console.WriteLine("The second job's description: {0} 
Total time needed to complete the job: {1} hours 
Hourly fee: {2} per hour", job2.Description, job2.Time, job2.Rate.ToString("C"));
     TotalPay(job2);         

     Console.WriteLine("The third job's description: {0} 
Total time needed to complete the job: {1} hours 
Hourly fee: {2} per hour", job3.Description, job3.Time, job3.Rate.ToString("C"));
     TotalPay(job3);
  }

  public static void TotalPay(Job method)
  {

     double totalFee = Job.rate * Job.time;
     Console.WriteLine("The total fee is: {0}", TotalFee.ToString("C"));
  }
}

class Job
{

  public Job(string description, double time, double rate)
  {
     Description = description;

     Time = time;

     Rate = rate;
  }

  public static Job operator+(Job first, Job second)
  {
     string newDescription = first.Description + " and " + second.Description;

     double newTime = first.Time + second.Time;

     double newRate = (first.Rate + second.Rate) / 2;

     double newTotalFee = newRate * newTime;

     return(new Job(newDescription, newTime, newRate));
  }

  public string Description {get; set;}
  public double Time {get; set;}
  public double Rate {get; set;}
}

推荐答案

你没有为你的类指定可见性修饰符，这使它成为内部的.

You haven't specified a visibility modifier for your class, which makes it internal.

尝试更改此行:

class Job

到这里:

public class Job
