在quartz.net的JobBuilder的Create方法中的类的实例

JobBuilder默认的创建方法是

IJobDetail paymentJob = JobBuilder.Create<Hello>().WithIdentity(jobName, groupName).Build();

我检查了重载，但是没有重载，我们可以在里面有一个类的实例。create方法。像这样

IJobDetail paymentJob = JobBuilder.Create<new Hello()>().WithIdentity(jobName, groupName).Build();

但是这会给出一个错误

操作符& lt;不能应用于'method group'或'Hello'

我需要这个的原因是:

public abstract class Hello:IJob
{
    public abstract void Execute(IJobExecutionContext context);
}
public Hello1: Hello
{
    public void Execute(IJobExecutionContext context)
    {
        //implementation
    }
}
public Hello2: Hello
{
    public void Execute(IJobExecutionContext context)
    {
        //implementation
    }
}
public static HelloFactory
{
    public Hello GetHelloType(HelloEnum enum)
    {
        Hello job = new Hello();
        switch(enum)
        {
            case HelloEnum.Type1: job = new Hello1();
            case HelloEnum.Type2: job = new Hello2();
        }
    }
}

public static class HelloFactory
{
    public Type GetHelloType(HelloEnum theEnum)
    {
        Type type;
        switch (theEnum)
        {
            case HelloEnum.Type1:
                type = typeof(Hello1);
                break;
            case HelloEnum.Type2: job = typeof(Hello2);
                break;
        }
    }
}
