WorkflowApplication(Activity)

使用指定的工作流程定義，建立 WorkflowApplication 類別的新執行個體。

public:
 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)

參數

workflowDefinition: Activity

工作流程定義。

範例

下列範例會使用 WorkflowApplication 來裝載工作流程。系統會使用由單一 DiceRoll 活動組成的工作流程定義來建構 WorkflowApplication 執行個體。 DiceRoll 活動具有兩個輸出引數，這些引數代表擲骰作業的結果。當工作流程完成時，Completed 處理常式就會擷取輸出，而且主控台會顯示下列輸出。

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();

適用於

WorkflowApplication(Activity, WorkflowIdentity)

使用指定的工作流程定義和定義識別，建立 WorkflowApplication 類別的新執行個體。

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

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

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

Public Sub New (workflowDefinition As Activity, definitionIdentity As WorkflowIdentity)

參數

workflowDefinition: Activity

工作流程定義。

definitionIdentity: WorkflowIdentity

定義識別。

適用於

WorkflowApplication(Activity, IDictionary<String,Object>)

建立使用指定工作流程定義及引數值的 WorkflowApplication 類別新執行個體。

public:
 WorkflowApplication(System::Activities::Activity ^ workflowDefinition, System::Collections::Generic::IDictionary<System::String ^, System::Object ^> ^ inputs);

public WorkflowApplication (System.Activities.Activity workflowDefinition, System.Collections.Generic.IDictionary<string,object> inputs);

new System.Activities.WorkflowApplication : System.Activities.Activity * System.Collections.Generic.IDictionary<string, obj> -> System.Activities.WorkflowApplication

Public Sub New (workflowDefinition As Activity, inputs As IDictionary(Of String, Object))

參數

workflowDefinition: Activity

工作流程定義。

inputs: IDictionary<String,Object>

在工作流程定義的根活動上定義的引數值，以引數名稱做為索引鍵。

範例

下列範例會使用 WorkflowApplication 來裝載工作流程。 WorkflowApplication實例是使用工作流程定義來建構，其中包含接受兩個輸入自變數的單Divide一活動，以及包含要傳遞之兩個值的輸入自變數字典，並以自變數名稱為索引鍵。系統會處理所需的工作流程開發週期事件，並且透過呼叫 Run 叫用此工作流程。當工作流程完成時，主控台就會顯示下列輸出。

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);
        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("{0} / {1} = {2} Remainder {3}",
            dividend, divisor, e.Outputs["Result"], e.Outputs["Remainder"]);
    }
};

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