背景工作者(Background worker)

 如果我有一组操作，我想根据特定条件在后台工作程序中运行，例如，我有10个条件 
 
if(a)
    BackgroundWorker doA = new backgroundworker()
if(b) 
    BackgroundWorker doB = new backgroundworker()
if(c) 
    BackgroundWorker doC = new backgroundworker()
if(d) 
    BackgroundWorker doD = new backgroundworker()
...
...
 
 每个后台工作人员都需要一个dowork，runworkercompleted等....无论如何都要避免这样做，因此它会使代码变得不那么混乱/污染，因为其中一些方法可能会很大？ 
 
 谢谢 

If i have a set of actions i want to run in a background worker based on a certain condition and i have 10 conditions, for example
 
if(a)
    BackgroundWorker doA = new backgroundworker()
if(b) 
    BackgroundWorker doB = new backgroundworker()
if(c) 
    BackgroundWorker doC = new backgroundworker()
if(d) 
    BackgroundWorker doD = new backgroundworker()
...
...
 
each of those background workers will require a dowork, runworkercompleted etc.... is there anyway to avoid that so it makes the code less messy/clutered as some of those methods might be quite big?
 
thanks
