假设我有这样的类和接口结构：

interface IService {}
interface IEmailService : IService
{
    Task SendAsync(IMessage message);
}

class EmailService : IEmailService
{
    async Task SendAsync(IMessage message)
    {
        await ...
    }
}

interface ICircuitBreaker<TService> : IService where TService : IService
{
    TService Service { get; set; }
    Task<IResult> PerformAsync(Func<Task<Iresult>> func);
}

class EmailServiceCircuitBreaker : ICircuitBreaker<IEmailService>
{
    IEmailService Service { get; set; }

    public EmailServiceCircuitBreaker(IEmailService service)
    {
        Service = service;
    }

    public async Task<IResult> PerformAsync(Func<Task<Iresult>> func)
    {
        try
        {
            func();
        }
        catch(Exception e){//Handle failure}
    }
} …
