切库时偶发问题

[XuMengEnEli]

没有GetDatabase时一切功能正常，当使用了这个方法后会时不时的报这个异常

• 异常信息：

• 使用场景
  

• 封装的helper类

static GetDatabase 就是错误的设计

除了顶层 RedisClient 支持多线程安全

[2881099]

GetDatabase 返回的虽然是 RedisClient，它但只是一个单一 socket 连接，不支持多线程同时访问的

[XuMengEnEli]

感谢您的回复，之前不是static的，而是在方法里每次调用时进行切换，但会在运行一段时间后报这个错误（这个链接点进去竟然是FreeSql，哈哈~）

因为你每次 GetDatabase，并且不 Dispose 归还资源，把 pool 用完了

[XuMengEnEli]

非常感谢您的指点，我这样做是不是就可以了

[2881099]

using {
}

否则，你的循环很大的情况下，不会马上 dispose，语法糖有毒的。
