只需要逐个注册所有 IRule 实现即可。 MS.Ext.DI库可以将其解析为 IEnumerable< T> 。

It's just a matter of registering all IRule implementations one by one; the MS.Ext.DI library can resolve it as an IEnumerable<T>.

services.AddTransient<IRule, Rule1>();
services.AddTransient<IRule, Rule2>();
services.AddTransient<IRule, Rule3>();
services.AddTransient<IRule, Rule4>();
