WorkflowApplicationCompletedEventArgs.Outputs 属性

定义

命名空间:

System.Activities

程序集:

System.Activities.dll

获取一个字典，该字典包含工作流实例的根活动的 OutArgument 的值（由自变量名称键控）。

public:
 property System::Collections::Generic::IDictionary<System::String ^, System::Object ^> ^ Outputs { System::Collections::Generic::IDictionary<System::String ^, System::Object ^> ^ get(); };

public System.Collections.Generic.IDictionary<string,object> Outputs { get; }

member this.Outputs : System.Collections.Generic.IDictionary<string, obj>

Public ReadOnly Property Outputs As IDictionary(Of String, Object)

属性值

IDictionary<String,Object>

示例

下面的代码示例检查传递给 WorkflowApplicationCompletedEventArgs 实例的 Completed 处理程序的 WorkflowApplication，并显示有关工作流完成情况的信息。

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);

        // Retrieve the outputs of the workflow.
        foreach (var kvp in e.Outputs)
        {
            Console.WriteLine("Name: {0} - Value {1}",
                kvp.Key, kvp.Value);
        }

        // Outputs can be directly accessed by argument name.
        Console.WriteLine("The winner is {0}.", e.Outputs["Winner"]);
    }
};
