範例

下列範例示範如何從衍生類別的建構函式呼叫基底 ExternalDataEventArgs 建構函式。 此範例來自 Ordering State Machine SDK 範例。 如需詳細資訊，請參閱 排序狀態機器範例。

public override void Dispose()
{
    try
    {
        IDesignerLoaderHost host = LoaderHost;
        if (host != null)
        {
            host.RemoveService(typeof(IIdentifierCreationService));
            host.RemoveService(typeof(IMenuCommandService));
            host.RemoveService(typeof(IToolboxService));
            host.RemoveService(typeof(ITypeProvider), true);
            host.RemoveService(typeof(IWorkflowCompilerOptionsService));
            host.RemoveService(typeof(IEventBindingService));
        }
    }
    finally
    {
        base.Dispose();
    }
}

Public Overrides Sub Dispose()
    Try
        Dim host As IDesignerLoaderHost = LoaderHost
        If host IsNot Nothing Then
            host.RemoveService(GetType(IIdentifierCreationService))
            host.RemoveService(GetType(IMenuCommandService))
            host.RemoveService(GetType(IToolboxService))
            host.RemoveService(GetType(ITypeProvider), True)
            host.RemoveService(GetType(IWorkflowCompilerOptionsService))
            host.RemoveService(GetType(IEventBindingService))
        End If
    Finally
        MyBase.Dispose()
    End Try
End Sub

ExternalDataEventArgs()

public:
 ExternalDataEventArgs();

public ExternalDataEventArgs ();

Public Sub New ()

ExternalDataEventArgs(Guid)

使用工作流程的實例標識碼，初始化 ExternalDataEventArgs 類別的新實例。

public:
 ExternalDataEventArgs(Guid instanceId);

public ExternalDataEventArgs (Guid instanceId);

new System.Workflow.Activities.ExternalDataEventArgs : Guid -> System.Workflow.Activities.ExternalDataEventArgs

Public Sub New (instanceId As Guid)

參數

instanceId

Guid
