Call webservice asynchronously and wait for all threads to be finished

Question

I need to call the web service several times to get data, and then put those data into my database, so I\'ve got the following code:

foreach (string v in options         


        

Answer 1

This would initiate asynchronous call

 public delegate IList SaveToDb(IList myParam);
 SaveToDb _saveToDb= new SaveToDb(objService.SaveToDb);
 IAsyncResult asyncSearchResult = saveToDb.BeginInvoke(input,null,null)

This would wait for execution to complete and return value:-

IList result=asyncSearchResult EndInvoke();
