CodeCondition.Condition 事件

定义

命名空间:

System.Workflow.Activities

程序集:

System.Workflow.Activities.dll

在计算条件时发生。

public:
 event EventHandler<System::Workflow::Activities::ConditionalEventArgs ^> ^ Condition;

public event EventHandler<System.Workflow.Activities.ConditionalEventArgs> Condition;

member this.Condition : EventHandler<System.Workflow.Activities.ConditionalEventArgs> 

Public Custom Event Condition As EventHandler(Of ConditionalEventArgs) 

事件类型

EventHandler<ConditionalEventArgs>

示例

下面的代码演示如何为当前的 Condition 实例附加 CodeCondition 事件处理程序。 此代码示例摘自 SimpleCAGWorkflow.designer.cs 文件中的“ConditionedActivityGroup”SDK 示例。 有关详细信息，请参阅 Using ConditionedActivityGroup。

this.CanModifyActivities = true;
System.Workflow.Activities.CodeCondition codecondition1 = new System.Workflow.Activities.CodeCondition();
System.Workflow.Activities.CodeCondition codecondition2 = new System.Workflow.Activities.CodeCondition();
this.BookingCag = new System.Workflow.Activities.ConditionedActivityGroup();
this.Car = new System.Workflow.Activities.CodeActivity();
this.Airline = new System.Workflow.Activities.CodeActivity();
//
// BookingCag
//
this.BookingCag.Activities.Add(this.Car);
this.BookingCag.Activities.Add(this.Airline);
this.BookingCag.Name = "BookingCag";
codecondition1.Condition += new System.EventHandler<System.Workflow.Activities.ConditionalEventArgs>(this.CarCondition);
//
// Car
//
this.Car.Name = "Car";
this.Car.ExecuteCode += new System.EventHandler(this.Car_ExecuteCode);
this.Car.SetValue(System.Workflow.Activities.ConditionedActivityGroup.WhenConditionProperty, codecondition1);
codecondition2.Condition += new System.EventHandler<System.Workflow.Activities.ConditionalEventArgs>(this.AirlineCondition);

Me.CanModifyActivities = True
Dim codecondition1 As New System.Workflow.Activities.CodeCondition()
Dim codecondition2 As New System.Workflow.Activities.CodeCondition()
Me.BookingCag = New System.Workflow.Activities.ConditionedActivityGroup()
Me.Car = New System.Workflow.Activities.CodeActivity()
Me.Airline = New System.Workflow.Activities.CodeActivity()
' 
' BookingCag
'
Me.BookingCag.Activities.Add(Me.Car)
Me.BookingCag.Activities.Add(Me.Airline)
Me.BookingCag.Name = "BookingCag"
AddHandler codecondition1.Condition, AddressOf CarCondition
' 
' Car
' 
Me.Car.Name = "Car"
AddHandler Car.ExecuteCode, AddressOf Me.Car_ExecuteCode
Me.Car.SetValue(System.Workflow.Activities.ConditionedActivityGroup.WhenConditionProperty, codecondition1)
AddHandler codecondition2.Condition, AddressOf Me.AirlineCondition
