Background worker

Question

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

Answer 1

You should use Task from the System.Threading.Tasks namespace instead, it's very simple and easy to use.

To start a task, you can simply use: Task.Factory.StartNew() passing a method or a lambda expression as a parameter. you get back a Task object that you can use for continuation, getting the result back, etc.

You can consider using a single backgroundworker and passing an argument to it.Using this argument in the DoWork method you can determine which block of code to work.Check this thread

为什么不将需要评估的对象传递给BackgroundWorker，而BackgroundWorker可以使用它来确定要做什么？
