  NameDescription
Public propertyArgumentTypeGets the data type for the data bound to this Argument. (Inherited from Argument.)
Public propertyDirectionGets an ArgumentDirection that specifies whether the Argument represents the flow of data into an activity, out of an activity, or both into and out of an activity. (Inherited from Argument.)
Public propertyEvaluationOrderGets or sets a zero-based value that specifies the order in which the argument is evaluated. (Inherited from Argument.)
Public propertyExpressionGets an Activity<TResult> that represents the value of this InArgument<T>.

  NameDescription
Public operatorStatic memberImplicit(T to InArgument<T>)Initializes and returns a new InArgument<T> using the specified value.
Public operatorStatic memberImplicit(Activity<T> to InArgument<T>)Initializes and returns a new InArgument<T> using the specified Activity<TResult>.

In this example, a workflow is created that consists of a single WriteLine activity. The WriteLine activity has an InArgument<T> named Text. The host application creates an instance of the workflow and passes a string, which maps to the Text argument of the WriteLine and is used by the WriteLine activity.

Activity wf = new WriteLine();

Dictionary<string, object> wfParams = new Dictionary<string, object>();
wfParams.Add("Text", "Hello World!");

WorkflowInvoker.Invoke(wf, wfParams);
