The "score" doesn't work anymore. How come?

Hey,

Tried both writing the entire exercise myself and using the solution-files through the download. Same gives 0.00% for the "score" on all players. I can see how it is correct incoming sentiment.Score but as soon as it goes to out score, it transform to 0.

Might this be due to new version of Json? (it was 8.X when this video was released and now its 10.x)

Anyone got a clue as to what is doing this?

Thimmy,

Sorry to hear that you're running into an issue reproducing what's shown in the course. The Text Analytics API has changed since the video was recorded, so that might be contributing to the problem. I'll try to take a look at this soon.

In the meantime, is there any chance that you could share your code with me?

Thanks ~James

Not sure if it's the same problem, but I had the issue with double.TryParse not properly parsing the string into a double as well. It seems double.TryParse uses localization to parse the string, and since we use the comma as a decimal separator here (Netherlands, and I think the whole of Europe), TryParse wouldn't parse properly. I fixed this by changing it to the following:

double.TryParse(sentiment.Score, NumberStyles.Any, CultureInfo.GetCultureInfo("en-US"), out score)

Hope this fixes it for you as well.

danielterhorst - Seems to have fixed it! That together with the Repel working really bad for someone with a nordic keyboard setting makes a bit grumpy. Sorry for late reply to everyone, I really appreciate the help. Been away from the location I had the code at until today so it's been difficult to review the replies.

danielterhorst,

Great job finding the solution and thanks for sharing it with everyone! I've updated the Teacher's Notes for this video to include information about this important workaround.

Thanks ~James

Can you please add the Simon McGuirk's response, to change the type of the Score property from float to string? It's helpful.

I was still having an issue with TryParse today. Took a while but eventually found that when I created the SentimentResponse class and used the Paste as Json option, Score was set to be of type float and instead of string. Changed it to string and error went away.

  public string Score { get; set; }
