Background Worker and returning values
Hello all. Morning question...
I have the main thread running my main form. I use a backgroundworker when user click button to use a webservice that controls european VAT. my code is:
//...
MBForm.Showdialog() // form whre is shown the progress of the webservice running on the Background Thread
Backgroundworker.RunWorker
//... BackGroundWorker_Dowork()
Webservice.run()
All that I need is: How can I have retuning values when the background worker has finished the work? I mean the Webservice is controlling the european VAT returning bool valid and string name and string address. How can I have this three returning values for using it on the main Thread? Do I have to assingn these values on a global variable of is there a better way? Thx in advance

Sorry Alex, just one more thing...
OperationResult r = new Result(); // OperationResult is your class which contains results of background operation
r.Name = ...;
r.Address = ...; // fill result properties
What is the best way to create OperationResult class?
public class Operation Result
{
string name;
string address
OperationResult(string _name, string address)
{
name=_name;
address = _address;
}
}
Or is there a better way to create an object assigning to properties to it? Thx again

Any way that is convenient for you: class with constructor and read-only properties, class with read/write properties. Anything that allows to keep information and read it. As example of such clas, which is designed only for keeping parameters, see ProcessStartInfo class.
