I started a new application which utilizes the Omdb API to retrieve movie information. the goal of the application is to retrieve a movie title using a search keyword. ex: "shawshank" should return :
{"Search":[{"Title":"The Shawshank Redemption","Year":"1994","imdbID":"tt0111161","Type":"movie","Poster":"https://m.media-amazon.com/images/M/MV5BMDFkYTc0MGEtZmNhMC00ZDIzLWFmNTEtODM1ZmRlYWMwMWFmXkEyXkFqcGdeQXVyMTMxODk2OTU@._V1_SX300.jpg"},{"Title":"Shawshank: The Redeeming Feature","Year":"2001","imdbID":"tt0293927","Type":"movie","Poster":"https://m.media-amazon.com/images/M/MV5BYjgwMjNjOGUtNzU3MC00MGM5LTk4NTctNGI5N2I2NGI0YjBhXkEyXkFqcGdeQXVyMjIzMTk0MzM@._V1_SX300.jpg"},{"Title":"Hope Springs Eternal: A Look Back at 'The Shawshank Redemption'","Year":"2004","imdbID":"tt0443041","Type":"movie","Poster":"N/A"},{"Title":"The Shawshank Redemption: Cast Interviews","Year":"2004","imdbID":"tt5443390","Type":"movie","Poster":"N/A"},{"Title":"The Shawshank Redemption (Scene)","Year":"2012","imdbID":"tt2477746","Type":"movie","Poster":"N/A"},{"Title":"The Shawshank Reflection","Year":"2015","imdbID":"tt3882670","Type":"movie","Poster":"N/A"},{"Title":"The Shawshank Redemption: Behind the Scenes","Year":"2004","imdbID":"tt5443386","Type":"movie","Poster":"N/A"}],"totalResults":"7","Response":"True"}
The problem is once I run my form application, I attempt to save the json into an object assuming that if my object parameters are the same (case insensitive) name the JSON items will be saved into the corresponding variables inside the object. This does not happen as the object parameters remain null.
This code was made by following a youtube video about making an app which pulls an online comic using an API. I wanted to instead pull movie titles from the Omdb. Nugets which were used are: Microsoft.AspNet.WebApi.Client v5.2.7 and Newtonsoft.Json v12.0.2. The link of the video which was used to make this is as follows: https://www.youtube.com/watch?v=aWePkE2ReGw
I have tried testing my url in browser and it successfully generates the desired JSON. I have also tried stepping through the code and watching variables I noticed that no data is successfully being pulled from the url. I am very new to making HTTP connections as well as using API's so it might be an easy fix. After running the code the results of the variables being watched are as follows:
Name Value Type
Title "MainWindow" string
movie {Movie_application.MovieModel} Movie_application.MovieModel
Film.Title null string
url"http://www.omdbapi.com/?s=shawshank&apikey=568027e4" string
Tag null object
Title "MainWindow" string
Film {Movie_application.MovieModel} Movie_application.MovieModel
titlee null string

I expect the code to be able to write "The Shawshank Redemption" onto the form text box. The text box remains empty at the end of the run. Thanks in advance.
