ReplicatorActivity.UntilCondition 属性

  • 参考

定义

命名空间:
System.Workflow.Activities
程序集:
System.Workflow.Activities.dll

获取或设置指示 ReplicatorActivity 何时应完成的完成条件。

public:
 property System::Workflow::ComponentModel::ActivityCondition ^ UntilCondition { System::Workflow::ComponentModel::ActivityCondition ^ get(); void set(System::Workflow::ComponentModel::ActivityCondition ^ value); };
public System.Workflow.ComponentModel.ActivityCondition UntilCondition { get; set; }
member this.UntilCondition : System.Workflow.ComponentModel.ActivityCondition with get, set
Public Property UntilCondition As ActivityCondition

属性值

ActivityCondition

确定 ActivityCondition 是否完成的 ReplicatorActivity。

示例

下面的代码示例演示如何将 UntilCondition 属性的值设置为 null，这意味着 ReplicatorActivity 永远都不会关闭。 此代码示例摘自 SimpleReplicatorWorkflow.Designer.cs 文件中的“复制器”SDK 示例。 有关详细信息，请参阅 使用复制程序。

public sealed partial class ThrowWorkflow : SequentialWorkflowActivity
{
    [System.Diagnostics.DebuggerNonUserCode()]
    private void InitializeComponent()
    {
        this.CanModifyActivities = true;
        System.Workflow.ComponentModel.ActivityBind activitybind1 = new System.Workflow.ComponentModel.ActivityBind();
        this.throwActivity1 = new System.Workflow.ComponentModel.ThrowActivity();
        activitybind1.Name = "ThrowWorkflow";
        activitybind1.Path = "ThrownException";
        //
        // throwActivity1
        //
        this.throwActivity1.Name = "throwActivity1";
        this.throwActivity1.SetBinding(System.Workflow.ComponentModel.ThrowActivity.FaultProperty, ((System.Workflow.ComponentModel.ActivityBind)(activitybind1)));
        //
        // ThrowWorkflow
        //
        this.Activities.Add(this.throwActivity1);
        this.Name = "ThrowWorkflow";
        this.CanModifyActivities = false;
    }

    private Exception thrownExceptionValue = new System.Exception("My Exception Message.");

    public Exception ThrownException
    {
        get { return thrownExceptionValue; }
        set { thrownExceptionValue = value; }
    }

    private ThrowActivity throwActivity1;
}

Partial Public NotInheritable Class ThrowWorkflow
    Inherits SequentialWorkflowActivity

    <System.Diagnostics.DebuggerNonUserCode()> _
                                        Private Sub InitializeComponent()

        Me.CanModifyActivities = True
        Dim activitybind1 As New System.Workflow.ComponentModel.ActivityBind()
        Me.throwActivity1 = New System.Workflow.ComponentModel.ThrowActivity()
        activitybind1.Name = "ThrowWorkflow"
        activitybind1.Path = "ThrownException"
        ' 
        ' throwActivity1
        ' 
        Me.throwActivity1.Name = "throwActivity1"
        Me.throwActivity1.SetBinding(System.Workflow.ComponentModel.ThrowActivity.FaultProperty, activitybind1)
        ' 
        ' ThrowWorkflow
        ' 
        Me.Activities.Add(Me.throwActivity1)
        Me.Name = "ThrowWorkflow"
        Me.CanModifyActivities = False

    End Sub

    Private thrownExceptionValue As New System.Exception("My Exception Message.")

    Public Property ThrownException() As Exception
        Get
            Return thrownExceptionValue
        End Get
        Set(ByVal value As Exception)
            thrownExceptionValue = value
        End Set
    End Property

    Private throwActivity1 As ThrowActivity

End Class

注解

此默认条件是若要完成 ReplicatorActivity，所有子实例必须完成。

与 ConditionedActivityGroup 一样，可以使用规则条件或代码条件指定完成条件。
