将InArguments绑定到子活动 [英] Binding InArguments to child activities

问题描述

我在设计器中创建了一个活动(称为MyWorkflow)，该活动具有InArgument< bool>.名为IsClean.我将自定义CodeActivity添加到了序列中，该序列还具有InArgument< bool>.名为IsClean.在设计器中，我将代码活动的IsClean参数设置为IsClean，该参数应该是MyWorkflow的参数.

I have an activity created (call it MyWorkflow) in the designer that has an InArgument<bool> named IsClean.  I added a custom CodeActivity to the sequence that also has an InArgument<bool> named IsClean.  In the designer, I set the IsClean argument of the code activity to be IsClean, which should be the argument from MyWorkflow.

我已经尝试用相对较新的方式来对此进行复制，并且我的解决方案可以构建并正常运行.我无法重现此错误.您使用的是哪个版本?

自上次发行以来，此问题可能已得到修复.

这是我的代码活动和工作流程:

    公共密封类CodeActivity1:CodeActivity
{
       //定义字符串类型的活动输入参数
       public InArgument< bool>文字{get;放; }

Hi Jason,

I've tried to repro this with relatively recent bits, and my solution builds and runs properly.  I haven't been able to reproduce this error.  Which build are you using?  It is possible that this has been fixed since the last release.

For reference, here is my code activity and workflow:

    public sealed class CodeActivity1 : CodeActivity
    {
        // Define an activity input argument of type string
        public InArgument<bool> Text { get; set; }

       //如果您的活动返回值，则从CodeActivity< TResult>
派生//，然后从Execute方法返回值.
      受保护的重写void Execute(CodeActivityContext上下文)
{
                       //获取Text输入参数的运行时值
布尔文本= context.GetValue(this.Text);
Console.WriteLine(text.ToString());
        }
    }
