RuoVea.ExCache 8.0.1

RuoVea.ExCache

介绍

缓存帮助类库

1、快速入门

通过Nuget安装组件

Install-Package RuoVea.ExCache

2、使用示例

    // 写入值
    bool bolset = ExCache.CacheOptions.CaChe.Write("demo", "assadasdasdasdasdasas");
    // 获取值
    var getValue = ExCache.CacheOptions.CaChe.Read("demo");
    // 获取值无则用表达式写入
    CacheFactery.CaChe.Cof_ReadWrite<string>("permission_142307070910551", () => { return "获取值"; }, new TimeSpan(3));

3、所有接口方法
