试图了解DelegateInArgument，ActivityAction [英] Trying to understand DelegateInArgument, ActivityAction

问题描述

我很难理解DelegateInArgument的使用以及诸如ActivityAction之类的东西.编写以下代码:

静态 void Main(

I am having a difficult time understanding the use of DelegateInArgument and things such as ActivityAction. Take the following piece of code:

static void Main(string[] args)

         {

;  var ArgsToProcess = 新 列表< 字符串> {"arg_one" ，"arg_two" ，};

            var ArgsToProcess = new List<string> { "arg_one", "arg_two", "arg_three" };

 

;  var 委托Arg = 新 DelegateInArgument < 字符串> {名称= "s" };

            var delegateArg = new DelegateInArgument<string> { Name = "s" };

 

;  活动 toRun = 新 ParallelForEach < ; 字符串>

            Activity toRun = new ParallelForEach<string>

;  {

;    正文= 新 ActivityAction < 字符串 >

                Body = new ActivityAction<string>

;     {

;       参数=委托Arg，

;       处理程序= 新 Workflow1 () 

                    Handler = new Workflow1() 

;         {n
  ;             Arg =代表Arg 

;        }

;     }

;  };

 

;  WorkflowInvoker .调用(toRun，新 词典< 字符串，对象>

            WorkflowInvoker.Invoke(toRun, new Dictionary<string, object>

;     {

;        {值" ，ArgsToProcess}

                    {"Values", ArgsToProcess}

;     });

         }

1.为什么我的InArgument不能用作DelegateInArgument?
2.为什么仍然要使用DelegateInArgument?
3.

我试图找出如何从头开始(以编程方式)并创建工作流，但是我发现缺少这些项目的MSDN文档.

谢谢！

Answers question 3 but not necessarily 1 and 2 I don't think.
