Set ApartmentState on a Task

Question

I am trying to set the apartment state on a task but see no option in doing this. Is there a way to do this using a Task?

for (int i = 0; i < zom.Count; i++) {      Task t = Task.Factory.StartNew(zom[i].Process);      t.Wait(); } 

Answer 1

When StartNew fails you just do it yourself:

public static Task<T> StartSTATask<T>(Func<T> func) {     var tcs = new TaskCompletionSource<T>();     Thread thread = new Thread(() =>     {         try         {             tcs.SetResult(func());         }         catch (Exception e)         {             tcs.SetException(e);         }     });     thread.SetApartmentState(ApartmentState.STA);     thread.Start();     return tcs.Task; } 

(You can create one for Task that will look almost identical, or add overloads for some of the various options that StartNew has.)

An overload of Servy's answer to start a void Task

public static Task StartSTATask(Action func) {     var tcs = new TaskCompletionSource<object>();     var thread = new Thread(() =>     {         try         {             func();             tcs.SetResult(null);         }         catch (Exception e)         {             tcs.SetException(e);         }     });     thread.SetApartmentState(ApartmentState.STA);     thread.Start();     return tcs.Task; }
