有关枚举方法的C＃问题 [英] C# question regarding enum methods
问题描述
嘿大家，我现在正在为学校做作业，我真的被困在这一部分。我盯着它，谷歌搜索几个小时，我有运气。我已经在下面列出了我到目前为止的内容。
方向不是那么好。
为4种图像状态创建一个公共枚举CharacterState：攻击，防御，空闲和死亡。
现在创建一个成员变量使用get
和set来保持字符状态和公共属性State。现在，填写get的默认行为并设置为return / set state of state。
任何帮助都会受到极大的限制！谢谢

使用System.Collections。 Generic;
使用System.Linq;

case CharacterState。 TakeDamage：
this.Source = TakeDamageImageSource;
break;
case CharacterState.Dead：
this.Source = DeadImageSource;

默认值：
this.Source = IdleImageSource;
休息;

我尝试了什么：
谷歌搜索各种各样的东西，我试图按照指示，但似乎没有任何工作
Hey everybody I'm currently doing an assignment for school and I'm really stuck on this part. I've staring at it and googling things for hours and I'm having any luck. I have included below what I have so far.
The directions aren't that good.
"Create a public enum CharacterState for the 4 image states: Attacking, Defending, Idle, and Dead.
Now create a member variable state to hold the character state and a public property State with a get
and set. For now, fill in the default behavior of get and set to return/set the value of state."
Any help would be greatly appeciated! Thank you

Googling various things, and I tried to follow the directions but nothing seems to be working
推荐答案
你定义这样的枚举：
you define enums like this:
public enum CharacterState{Attacking,Defending,Idle,Dead}
类变量应该是这样的：
编辑：改进了第二部分答案
the class variable should be like this:
improved second part of answer
class CharacterImage{
//member variable
private CharacterState characterState;
//property
public CharacterState State
{
get{return characterState;}
set(characterState=value;}
}
}
