在WF4 beta 2中从控制台读取 [英] Reading from the console in WF4 beta 2

问题描述

我正在尝试使用新的流程图活动从控制台读取用户输入，并看到WriteLine活动，但没有ReadLine或使用设计器的变量或参数赋值如何工作的示例(尤其是当存在多个时).  我搜索了2天才找到一个示例，并且只找到了在控制台上写一两个问候世界的文章，并立即着眼于高级主题，从而避免了这个基本问题.为了使事情更加令人沮丧，我看到了都柏林的一个视频，该视频具有自定义的ReadLine活动，但没有讨论它，也没有包含它的源代码.

我知道我只是忽略了这一点.任何帮助将不胜感激.

I am attempting to read user input from the console using the new flowchart activity and see a WriteLine activity but no ReadLine or an example of how variable or argument assignment would work using the designer (especially when there is more than one).  I have searched for 2 days to find an example and have only found articles that write a hello world or two to the console and proceed immediately to advanced topics avoiding this basic issue.  To make things even more frustrating I saw a video from Dublin that had a custom ReadLine activity but did not discuss it or include the source code for it. 

I know it is something I am simply overlooking.  Any help would be immensely appreciated.

推荐答案

您是否正在寻找如何实施ReadLine活动?顺便说一句，WF设计器将在属性"窗口中显示所有参数.

Are you looking for how to implement a ReadLine activity? BTW, WF designer will show all the arguments in Properties window.

    public sealed class ReadLine : CodeActivity
    {
        public OutArgument<string> Text { get; set; }

        protected override void Execute(CodeActivityContext context)
        {
            string text = Console.ReadLine();
            context.SetValue<string>(Text, text);
        }
    }

谢谢，
