错误CS0051（可访问性不一致：参数类型'工作'大于法“AddJobs.TotalPay（工作）”少访问） [英] Error CS0051 (Inconsistent accessibility: parameter type 'Job' is less accessible than method 'AddJobs.TotalPay(Job)')

问题描述

我编译和通过省略totalFee字段下成功运行的源代码。我怎样写totalFee进入这个程序，以便它可以精确计算出总的费用为每个作业（*率时间）？下面，你会看到我尝试使用的方法;它产生的错误CS0051（可访问性不一致：参数类型'工作'大于法AddJobs.TotalPay（工作）少访问）。

这源代码是响应以下分配：

解决方案

您避风港' ：T指定类，这使得它的内部能见度修改

尝试改变这一行：

这样：

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)').

This source code is in response to the following assignment:

"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."

Here is the source code:

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} \nTotal time needed to complete the job: {1} hours \nHourly fee: {2} per hour", job1.Description, job1.Time, job1.Rate.ToString("C"));
     TotalPay(job1);

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

     Console.WriteLine("The third job's description: {0} \nTotal time needed to complete the job: {1} hours \nHourly 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;}
}

解决方案

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

Try changing this line:

class Job

to this:

public class Job
