示例

下面的代码演示在工作流中使用单个引发活动来实现异常处理。 此示例包括调用构造函数。 此代码示例摘自 ThrowWorkflow.cs 文件中的“引发 SDK”示例。 有关详细信息，请参阅 使用引发。

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"

    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

ThrowActivity(String)

初始化 ThrowActivity 类的新实例，并初始化其名称。

public:
 ThrowActivity(System::String ^ name);

public ThrowActivity (string name);

new System.Workflow.ComponentModel.ThrowActivity : string -> System.Workflow.ComponentModel.ThrowActivity

Public Sub New (name As String)

参数

name

String

活动的用户定义名称。

例外

ArgumentNullException

identifier 为空引用（在 Visual Basic 中为 Nothing）。
