FlowDecision Class

A specialized FlowNode that provides the ability to model a conditional node with two outcomes.

System.Object
  System.Activities.Statements.FlowNode
    System.Activities.Statements.FlowDecision

Namespace:  System.Activities.Statements
Assembly:  System.Activities (in System.Activities.dll)

public sealed class FlowDecision : FlowNode

The FlowDecision type exposes the following members.

  NameDescription
Public methodFlowDecision()Creates a new instance of the FlowDecision class.
Public methodFlowDecision(Activity<Boolean>)Creates a new instance of the FlowDecision class with the specified condition.
Public methodFlowDecision(Expression<Func<ActivityContext, Boolean>>)Creates a new instance of the FlowDecision class with the specified condition.

  NameDescription
Public propertyConditionSpecifies the condition the FlowDecision is testing.
Public propertyFalseGets or sets the FlowNode that is executed when the condition evaluates to false.
Public propertyTrueGets or sets the FlowNode that is executed when the condition evaluates to true.

  NameDescription
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

FlowDecision uses a condition and defines actions to take if the condition is true or false.

The following code sample demonstrates creating a FlowDecision node. This example is from the Fault Handling in a Flowchart Activity Using TryCatch sample.


FlowDecision flowDecision = new FlowDecision 
{
    Condition = ExpressionServices.Convert<bool>((ctx) => discount.Get(ctx) > 0),
    True = discountApplied,
    False = discountNotApplied
};
