C＃只读属性来计算，他们应该是方法？ [英] C# read-only calculated properties, should they be methods?

问题描述

我有一个已经计算出对他们的领域，如TOTALCOST几个实体。现在，我把它们都作为属性，但我不知道他们是否实际上应该是方法。是否有此一C＃标准

 公共类工作单
 {
公众诠释LaborHours {得到什么？;组; } 
公共小数LaborRate {搞定;组; } 
 
 //如果这是LaborCost（）？ 
公共小数LaborCost 
 {
得到
 {
返回LaborHours * LaborRate; 
} 
} 
} 
  

解决方案

这是确定使用计算的特性，而不是方法，只要计算没有明显的时间

请参阅Property使用指南

I have several entities that have calculated fields on them such as TotalCost. Right now I have them all as properties but I'm wondering if they should actually be methods. Is there a C# standard for this?

public class WorkOrder
{
    public int LaborHours { get; set; }
    public decimal LaborRate { get; set; }

    // Should this be LaborCost()?
    public decimal LaborCost
    {
        get
        {
            return LaborHours * LaborRate;
        }
    }
}

解决方案

It's OK to use calculated properties rather than methods, as long as the calculation doesn't take a noticeable time
