 WorkflowApplication(System::Activities::Activity ^ workflowDefinition);

public WorkflowApplication(System.Activities.Activity workflowDefinition);

new System.Activities.WorkflowApplication : System.Activities.Activity -> System.Activities.WorkflowApplication

Public Sub New (workflowDefinition As Activity)

範例

下列範例使用 WorkflowApplication裝載工作流程。 WorkflowApplication實例是使用由單DiceRoll一活動組成的工作流程定義來建構。 活動 DiceRoll 有兩個輸出自變數，代表骰子滾滾作業的結果。 當工作流程完成後，處理器會擷取 Completed 輸出，並顯示以下輸出給主控台。

Workflow aae3fb48-7229-4737-b969-d63e131b96b3 Completed.
The two dice are 1 and 5.

public sealed class DiceRoll : CodeActivity
{
    public OutArgument<int> D1 { get; set; }
    public OutArgument<int> D2 { get; set; }

    static Random r = new Random();

    protected override void Execute(CodeActivityContext context)
    {
        D1.Set(context, r.Next(1, 7));
        D2.Set(context, r.Next(1, 7));
    }
}

 // Create a WorkflowApplication instance.
 WorkflowApplication wfApp = new WorkflowApplication(new DiceRoll());

 // Subscribe to any desired workflow lifecycle events.
 wfApp.Completed = delegate(WorkflowApplicationCompletedEventArgs e)
 {
     if (e.CompletionState == ActivityInstanceState.Faulted)
     {
         Console.WriteLine("Workflow {0} Terminated.", e.InstanceId);
         Console.WriteLine("Exception: {0}\n{1}",
             e.TerminationException.GetType().FullName,
             e.TerminationException.Message);
     }
     else if (e.CompletionState == ActivityInstanceState.Canceled)
     {
         Console.WriteLine("Workflow {0} Canceled.", e.InstanceId);
     }
     else
     {
         Console.WriteLine("Workflow {0} Completed.", e.InstanceId);

         // Outputs can be retrieved from the Outputs dictionary,
         // keyed by argument name.
         Console.WriteLine("The two dice are {0} and {1}.",
             e.Outputs["D1"], e.Outputs["D2"]);
     }
 };

// Run the workflow.
 wfApp.Run();

public:
 WorkflowApplication(System::Activities::Activity ^ workflowDefinition, System::Activities::WorkflowIdentity ^ definitionIdentity);

public WorkflowApplication(System.Activities.Activity workflowDefinition, System.Activities.WorkflowIdentity definitionIdentity);

範例

下列範例使用 WorkflowApplication裝載工作流程。 WorkflowApplication實例是透過一個工作流程定義建構，該定義包含一個接受兩個輸入參數的活動Divide，以及一個包含兩個要傳遞值的輸入參數字典，並以參數名稱鍵控。 處理所需的工作流程生命週期事件，並透過呼叫呼叫 Run來呼叫該工作流程。 工作流程完成時，主控台會顯示下列輸出。

Workflow 8dc844c1-bbf8-4b21-a9a2-05f89e416055 Completed
500 / 36 = 13 Remainder 32
Workflow 8dc844c1-bbf8-4b21-a9a2-05f89e416055 Unloaded.

public sealed class Divide : CodeActivity
{
    [RequiredArgument]
    public InArgument<int> Dividend { get; set; }

    [RequiredArgument]
    public InArgument<int> Divisor { get; set; }

    public OutArgument<int> Remainder { get; set; }
    public OutArgument<int> Result { get; set; }

    protected override void Execute(CodeActivityContext context)
    {
        int quotient = Dividend.Get(context) / Divisor.Get(context);
        int remainder = Dividend.Get(context) % Divisor.Get(context);

        Result.Set(context, quotient);
        Remainder.Set(context, remainder);
    }
}

int dividend = 500;
int divisor = 36;

Dictionary<string, object> inputs = new Dictionary<string, object>();
inputs.Add("Dividend", dividend);
inputs.Add("Divisor", divisor);

// Create a WorkflowApplication instance.
WorkflowApplication wfApp = new WorkflowApplication(new Divide(), inputs);

// Subscribe to any desired workflow lifecycle events.
wfApp.Completed = delegate(WorkflowApplicationCompletedEventArgs e)
{
    if (e.CompletionState == ActivityInstanceState.Faulted)
    {
        Console.WriteLine("Workflow {0} Terminated.", e.InstanceId);
