这样类属性的写法有没有不妥之处？

Question

 public CountWuYeFei WuYeFei
    {
        get
        {
            if (this.WuYeFei == null)
            {
                return _GetWuYeFeiDatails();
            }
            else
            {
                return this.WuYeFei;
            }        }
    }

Answer 1

有一点点，你先得声明一个私有的变量，然后再去定义属性，get是get这个变量的值private CountWuYeFei _wuYeFei=null;public CountWuYeFei WuYeFei
   {
   get
   {
   if (this.WuYeFei == null)
   {
   return _GetWuYeFeiDatails();
   }
   else
   {
   return this._wuYeFei;
   }   }
   }

Answer 2

private CountWuYeFei _WuYeFei
public CountWuYeFei WuYeFei
  {
  get
  {
  if (_WuYeFei == null)
  {
  return _GetWuYeFeiDatails();
  }
  else
  {
  return _WuYeFei;
  }  }
  }

Answer 3

为什么一定要写一个private,有什么好处？

Answer 4

private CountWuYeFei _WuYeFei;私有成员public CountWuYeFei WuYeFei;公共成员public CountWuYeFei WuYeFei 公共属性
{
  get{}
  set{}
}
