可能是有关c#6.0的报错 因为我用的还是vs2013

[顾西昂]

private static SimpleCacheProvider _instance = null;
        private readonly object _lockObj = new object();
        #region GetInstance
        /// <summary>  
        /// 获取缓存实例  
        /// </summary>  
        /// <returns></returns>  
        public static SimpleCacheProvider GetInstance()  
        {  
            if (_instance == null) lock(_lockObj){_instance =_instance?? new SimpleCacheProvider()};//报错的一行
            return _instance;  
        }
        #endregion

错误 2 非静态的字段、方法或属性“DDDemo.SimpleCacheProvider._lockObj”要求对象引用 D:\backup\Web\DDDemo\DDDemo\SimpleCacheProvider.cs 22 41 DDDemo
错误 1 应输入 ; D:\backup\Web\DDDemo\DDDemo\SimpleCacheProvider.cs 22 99 DDDemo

private static SimpleCacheProvider _instance = null; private static readonly object _lockObj = new object(); #region GetInstance /// <summary> /// 获取缓存实例 /// </summary> /// <returns></returns> public static SimpleCacheProvider GetInstance() { if (_instance == null) lock (_lockObj) { _instance = _instance ?? new SimpleCacheProvider(); };//报错的一行 return _instance; } #endregion

这是低级错误，在net1.0也编译不了

非静态方法可以访问类中的任何成员，静态方法只能访问类中的静态成员 http://www.cnblogs.com/NothingIsImpossible/archive/2010/07/28/1786706.html

引用 1 楼 yuankaiwsl 的回复:
