oauth2 c# example

[Tom Thomas]

Looking for a basic example implementing oauth2 in c# using headers.  This is code I've used for Salesforce oauth2.  

It would be great to hit the ground running with a working example....

Thanks!!!

public async Task AuthUser()

        {

            if (serviceUrl != null)

                return;

            HttpClient authClient;

            

            authClient = new HttpClient();

            HttpContent content = new FormUrlEncodedContent(new Dictionary<string, string>

                {

                    {"grant_type","password"},

                    {"client_id",ConsumerKey},

                    {"client_secret",ConsumerSecret},

                    {"username",Username},

                    {"password",Password}

                }

            );

            var url = IsSandboxUser.Equals("true", StringComparison.CurrentCultureIgnoreCase)

                   ? "https://test.salesforce.com/services/oauth2/token"

                   : "https://login.salesforce.com/services/oauth2/token";

            HttpResponseMessage message = await authClient.PostAsync(url, content).ConfigureAwait(false);

            string responseString = await message.Content.ReadAsStringAsync().ConfigureAwait(false);

            if (responseString.Contains("error_description"))

            {

                Log.Error(String.Format("Salesforce Authorization failed in SalesforeceRestService with: {0}", responseString));

            }

            else

            {

                JObject obj = JObject.Parse(responseString);

                oAuthToken = (string)obj["access_token"];

                serviceUrl = (string)obj["instance_url"];

            }

        }

Then once authenticated I add it to my header for subsequent call as follows..

request.Headers.Add("Authorization", "Bearer " + oAuthToken);
