Examples
The following code sample demonstrates assigning the Action property of a Catch<TException> activity. This example is from the Fault Handling in a Flowchart Activity Using TryCatch sample.
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
};
Remarks
The exception handler is represented by a ActivityAction<T> object.
