从未分配的c＃字段的默认值为0

Question

刚开始使用类。我的int age不适用于我的属性Age。它始终为0。

namespace ConsoleApp1 
{ 
    class Program 
    { 
     static void Main(string[] args) 
     { 
      Stuffers s = new Stuffers("Stuffy McStuff"); 
     } 
    } 

    class Stuffers 
    { 
     private int age; 
     public int Age 
     { 
      get { return age; } set { value = age; } 
     } 
    } 
}  

显示错误：

field age never assigned to, and will have default value of 0

原非MCVE代码

namespace ConsoleApp1 
{ 
    class Program 
    { 
     static void Main(string[] args) 
     { 
      Stuffers s = new Stuffers("Stuffy McStuff"); 
      Console.WriteLine(s.GetName()); 

      Console.Write("{0}, what is your age?", s.GetName()); 
      s.Age = Convert.ToInt32(Console.ReadLine()); 

      Stuffers s2 = new Stuffers("Leeroy"); 
      Console.WriteLine(s.GetAge()); 
     } 
    } 

    class Stuffers 
    { 
     private int age; 
     private string name; 
     public int Age 
     { 
      get { return age; } set { value = age; } 
     } 
     public Stuffers(string nameC) 
     { 
      name = nameC; 
     } 
     public string GetName() 
     { 
      return name; 
     } 
     public int GetAge() 
     { 
      return age; 
     } 
    } 
}  

Answer 1

这是错误的：

public int Age 
{ 
    get { return age; } set { value = age; } 
} 

它应该是：

public int Age 
{ 
    get { return age; } set { age = value; } 
} 

value是要分配的新值。 age是管家变量。

或者，你可以这样做：

public int Age { get; set; } 

不宣age。

此外，GetAge()方法似乎是多余的，它可能是更好的转GetName成只得到属性：

class Stuffers 
{ 
    public int Age 
    { 
     get; set; 
    } 
    public string Name { get; private set; } 
    public Stuffers(string nameC) 
    { 
     Name = nameC; 
    } 
} 

Answer 2

你是不是年龄的值设置为

更改此

public int Age 
{ 
    get { return age; } set { value = age; } 
} 

对此

public int Age 
{ 
    get { return age; } set { age = value; } 
}
