C# get object from asyncron task -

i startet thread programming in c#. , realy dont know if right community ask questions that. if not, im sorry.

i have 2 functions, start() , status(). in start() create new task like:

start() {    each(dir => listofalldirs) {        new task(() => { yr.loadallfiles(dir); }).start();    }  } 

so have 200 parallel tasks running code:

class yr {     list<values> rv = new list<values>();     public list<values> loadallfiles(string dir)     {        [...dostuff...]        rv.add(...);        rv.add(...);        rv.add(...);     }  } 

so dont know how access > 200 running threads data, before they're finished. i'm looking sth. like:

status(dir) {     int count = gettaskbyname[dir].rv.count; (????)     console.writeline("dir " + dir + "->" + count + "files checked"); } 

and final output:

dir aa -> 19 files checkes dir ab -> 12 files checkes dir bb -> 49 files checkes dir aa -> 29 files checkes 

so clear: 200 dirs, 200 tasks, running asyncron. how access specific task / data running task.

apparently, need take 200 directories , compute result each of them. plinq makes exceptionally easy:

var results = listofalldirs .asparallel() .select(dir => new { dir, result = yr.loadallfiles(dir) }) .tolist(); 

and there's list of directories plus computation result.

you can manually tasks well. in case want sequence this:

1. create tasks , store them
2. use task.waitall wait completion
3. use task.result on each task result
