porting your python example code to C# has caused some issues.

I am moving your python example/same code found at https://github.com/SafetyCulture/safetyculture-sdk-python

to C#.  I am using the structure of the API calls as a reference as to how to do the same in my C# code. 

I have questions and issues.

Let’s have a look at the Python code:

def get_user_api_token(logger):
    """
    Generate iAuditor API Token
    :param logger:  the logger
    :return:        API Token if authenticated else None
    """
    username = input("iAuditor username: ")
    password = getpass()
    generate_token_url = "https://api.safetyculture.io/auth"
    payload = "username=" + username + "&password=" + password + "&grant_type=password"
    headers = {
        'content-type': "application/x-www-form-urlencoded",
        'cache-control': "no-cache",
        'sc-integration-id': "safetyculture-sdk-python",
        'sc-integration-version': "4.x",
    }
    response = requests.request("POST", generate_token_url, data=payload, headers=headers)
    if response.status_code == requests.codes.ok:
        return response.json()['access_token']
    else:
        logger.error('An error occurred calling ' + generate_token_url + ': ' + str(response.json()))
        return None

How the headers of an API was set successfully was done by using the HTTPRequestMessage class and the .Header.Add command in C# but it did not work out this time.  Please advise.  See the screen shot here:
