Then, what's different and common in above code lines (aside of different types)?

    In first case a define the object and i create as a new httpclient

    in the second i declare ad object as a new streamreader using data from response .

    In the code of example i see i thought it works so 🙂

      Your error message means that in your code you have used something not initialized at that time. That's it.
