How to pass input and output through Code Editor

I want to return values from code editor. I created the property inside the class but I cannot access those variable out side world.

Assign argument direction to the property which value you want to access.[ArgumentDirection(Direction =DirectionType.Output)]

I tried with argument direction
[ArgumentDirection(Direction =DirectionType.Output)]
public string ResponseContent { get; set; }

how to map this variable to output parameter and access this variable in studio.
