C#如何分配静态类的默认属性值 [英] C# How to assign default property value of static class

问题描述

如何在 C# 中分配静态类的默认属性值?我正在尝试执行以下操作:

how can I assign default property value of static class in C#? I'm trying to do followings:

public class Unit
{
  public string Name;
  public double cConvertFromSI;
}

// want to do something like this:
public static Unit m  = (Name = "meter"; cConvertFromSI = 1;)
public static Unit mm = (Name = "millimeter"; cConvertFromSI = 1000;)
public static Unit in = (Name = "inch"; cConvertFromSI = 39.3701;)

推荐答案

首先，不要使用公共字段，使用带有 getter/setter 的属性，它会破坏封装.其次，您应该实例化 Unit 的对象并初始化属性.查看一些示例:

First thing, do not use public fields, use properties with getters/setters, it will break the encapsulation. Second, you should instance an object of Unit and initialize the properties. See some examples:

public class Unit
{
  public string Name { get; set; }
  public double cConvertFromSI { get; set; }
}

public static Unit m  = new Unit() { Name = "meter", cConvertFromSI = 1 };
public static Unit mm = new Unit() { Name = "millimeter", cConvertFromSI = 1000 };
public static Unit in = new Unit() { Name = "inch", cConvertFromSI = 39.3701 };
