类，结构或接口成员声明中的标记'='无效c＃

问题描述

这可能是一个简单的问题，但我不明白为什么会发生这种情况。这里是我的代码第一：

  using System; 
使用System.Collections.Generic; 
使用System.Linq; 
使用System.Text; 
使用System.Threading.Tasks; 
 
命名空间GameCore 
 {
 public class PlayerCharacter 
 {
 
 public void Hit（int damage）
 {
健康 -  =损害; 
 
 if（Health  {
 IsDead = true; 
} 
} 
 
 public int Health {get;私人设置; } = 100; 
 public bool IsDead {get;私人设置; } 
 
 
 $ b $ / code> 

现在Visual Studio正在为赋值符号（=）（根据标题）无效令牌错误，我看不出为什么。任何人都可以阐明这一点吗？

我要做的是将生命值设置为100，并且每次角色受到伤害时，健康就是降低。感谢所有。

我使用Visual Studio 2013 v12.0.40629.00更新5

解决方案

为自动实现的属性设置默认值仅在C＃版本6及更高版本中可用。在版本6之前，您必须使用构造函数并在其中设置默认值：

  public class PlayerCharacter {
 public int Health {get;私人设置; } 
 
 public PlayerCharacter（）
 {
 this.Health = 100; 
 
 
 code $ 
 
 
 
要启用VS2013的编译器，可以使用。
 
this may be a simple question for people, but I can't see why this is occurring.  here is my code 1st:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace GameCore
{
    public class PlayerCharacter
    {

        public void Hit(int damage)
        {
            Health -= damage;

            if (Health <= 0)
            {
                IsDead = true;
            }
        }

        public int Health { get; private set; } = 100;
        public bool IsDead{ get; private set; }

    }
}
now Visual studio is giving the Invalid token error on the assignment sign (=) (as per the title), and I can not see why.  can anyone shed light on this please?
What I'm trying to do is set the int of Health to 100, and each time a character takes damage, then Health is decreased.  Thanks all.
I'm using Visual Studio 2013 v12.0.40629.00 update 5
 解决方案 
Settting a default-value for auto-implemented properties is only available from C#-version 6 and upwards. Before Version 6 you have to use the constructor and set the default-value there:
public class PlayerCharacter {
    public int Health { get; private set; }

    public PlayerCharacter()
    {
        this.Health = 100;
    }
}
To enable the compiler for VS2013 you may use this approach.
