If::Then Property
.NET Framework (current version)
The activity to be executed if the activity’s Condition resolves to true.
Assembly: System.Activities (in System.Activities.dll)
public: [DependsOnAttribute("Condition")] property Activity^ Then { Activity^ get(); void set(Activity^ value); }
The following code sample demonstrates setting the Then property of an If activity. This example is from the Sending and Handling Faults sample.
new If { // check if the order is asking for Widgets Condition = new InArgument<bool>( (e) => po.Get(e).PartName.Equals("Widget") ), Then = new If { // check if we have enough widgets in stock Condition = new InArgument<bool>( (e) => po.Get(e).Quantity < 100 ), Then = new SendReply { DisplayName = "Successful response", Request = submitPO, Content = SendContent.Create(new InArgument<string>( (e) => string.Format("Success: {0} Widgets have been ordered!", po.Get(e).Quantity)) ) }, // if we don't have enough widgets, throw an unhandled exception from this operation's body Else = new Throw { Exception = new InArgument<Exception>((e) => new Exception("We don't have that many Widgets.")) } }, // if its not for widgets, reply to the client that we don't carry that part by sending back an expected fault type (POFault) Else = new SendReply { DisplayName = "Expected fault", Request = submitPO, Content = SendContent.Create(new InArgument<FaultException<POFault>>( (e) => new FaultException<POFault>( new POFault { Problem = string.Format("This company does not carry {0}s, but we do carry Widgets.", po.Get(e).PartName), Solution = "Try your local hardware store." }, new FaultReason("This is an expected fault.") ))) } }
