Ejemplos

En el ejemplo de código siguiente se muestra cómo asignar la propiedad Action de una Catch<TException> actividad. Este ejemplo procede del control de errores en una actividad de diagrama de flujo mediante el ejemplo TryCatch .

FlowStep mwkStep = new FlowStep
{
    Action = new TryCatch
    {
        DisplayName = "Try/Catch for Divide By Zero Exception",
        Try = new Assign
        {
            DisplayName = "discount = 15 + (1 - 1/numberOfKids)*10",
            To = new OutArgument<double>(discount),
            Value = new InArgument<double>((ctx) => (15 + (1 - 1 / numberOfKids.Get(ctx)) * 10))
        },
        Catches =
        {
             new Catch<System.DivideByZeroException>
             {
                 Action = new ActivityAction<System.DivideByZeroException>
                 {
                     Argument = ex,
                     DisplayName = "ActivityAction - DivideByZeroException",
                     Handler =
                         new Sequence
                         {
                             DisplayName = "Divide by Zero Exception Workflow",
                             Activities =
                             {
                                new WriteLine()
                                {
                                    DisplayName = "WriteLine: DivideByZeroException",
                                    Text = "DivideByZeroException: Promo code is MWK - but number of kids = 0"
                                },
                                new Assign<double>
                                {
                                    DisplayName = "Exception - discount = 0",
                                    To = discount,
                                    Value = new InArgument<double>(0)
                                }
                             }
                         }
                 }
             }
        }
    },
    Next = flowDecision
};
