这是次要的,我知道,但是我要说我有一个班级角色和一个班级能力(主要是因为这就是我正在做的事情). Class Character有六种能力(典型的D& D ……).基本上：
public class Character
{
public Character()
{
this.Str = new Ability("Strength","Str");
this.Dex = new Ability("Dexterity","Dex");
this.Con = new Ability("Constitution","Con");
this.Int = new Ability("Intelligence","Int");
this.Wis = new Ability("Wisdom","Wis");
this.Cha = new Ability("Charisma","Cha");
}
#region Abilities
public Ability Str { get; set; }
public Ability Dex { get; set; }
public Ability Con { get; set; }
public Ability Int { get; set; }
public Ability Wis { get; set; }
public Ability Cha { get; set; }
#endregion
}
和
public class Ability
{
public Ability()
{
score = 10;
}
public Ability(string Name,string Abbr)
: this()
{
this.Name = Name;
this.Abbr = Abbr;
}
public string Name { get; set; }
public string Abbr { get; set; }
public int score { get; set; }
public int Mod
{
get
{
return (score - 10) / 2;
}
}
}
在未来的代码中实际使用这些能力属性时,我希望能够默认只得分,如下所示：
//Conan hits someone
int damage = RollDice("2d6") + Conan.Str;
//evil sorcerer attack drains strength
Conan.Str = 0;
而不是：
//Conan hits someone
int damage = RollDie("2d6") + Conan.Str.score;
//evil sorcerer attack drains strength
Conan.Str.score = 0;
现在,第一种情况可以通过隐式转换来处理：
public static implicit operator int(Ability a)
{
return a.score;
}
可以有人帮我反过来吗？这样的隐式转换：
public static implicit operator Ability(int a)
{
return new Ability(){ score = a };
}
解决方法
首先,保持隐式转换：
public static implicit operator Ability(int a)
{
return new Ability(){ score = a };
}
然后在你的角色类中：为str添加一个private属性,并更改Str属性的getter和setter,如下所示：
private Ability str;
public Ability Str
{
get
{
return this.str;
}
set
{
if (value.Name == "")
{
this.str.score = value.score;
}
else
{
this.str = value;
}
}
}
你去:)
你也可以使用：
if(string.IsNullOrWhiteSpace(value.Name))
代替
if (value.Name == "")
如果您正在编译.NET 4.0版本
编辑：我给了你一个完全符合你想要的解决方案,但是ja72所写的内容对于操作符来说也是一个很好的建议 – 和;你可以将他的解决方案添加到我的(或者我的,无论如何),它会工作得很好.然后你就可以写：
Character Jax = new Character(); // Str.score = 10 Character Conan = new Character(); // Str.score = 10 Jax.Str = 2000; // Str.score = 2000; Conan.Str += 150; // Str.score = 160
