WorkflowApplicationCompletedEventArgs.Outputs 属性

定义

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)。Gets a dictionary that contains the values of OutArguments of the workflow instance's root activity, keyed by argument name.

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>

一个字典,该字典包含 OutArgument 工作流实例的根活动的的值,由参数名进行键控。A dictionary that contains the values of OutArguments of the workflow instance's root activity, keyed by argument name.

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。The following code example inspects the WorkflowApplicationCompletedEventArgs passed into the Completed handler of a WorkflowApplication instance and displays information about how the workflow completed.

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"]);
    }
};
