Twitter status update failed with Error: 'Could not authenticate with OAuth.' The following is the code I put in button1. How do I fix this error? Thanks
OAuthTokens tokens = new OAuthTokens();
tokens.AccessToken = "I put my accesstoken";
tokens.AccessTokenSecret = "I put my tokensecret";
tokens.ConsumerKey = "I put my consumer key";
tokens.ConsumerSecret = "I put consumer secret";
TwitterResponse<TwitterStatus> tweetResponse = TwitterStatus.Update(tokens, "sample tweet");
if (tweetResponse.Result == RequestResult.Success)
MessageBox.Show("Twitter status successfully posted");
else
label13.Text = string.Format("Twitter status update failed with Error: '{0}'",
tweetResponse.ErrorMessage);
