For some reason doesn't display a value when I press a button but doesn't know how to write correctly to output a value when I type a word and press a button


What I have tried:

        public IActionResult Index()
        {
            return View();

        }

        [HttpPost]
        public ActionResult Index(DictionaryResult dictionary)
        {
            string sentence = dictionary.Word;
            List<string> listOfWords = new List<string>(WordFixer.FixWords(sentence));
            List<DictionaryResult> dictionaryResult = new List<DictionaryResult>();

            foreach (var word in listOfWords)
            {
                try
                {
                    dictionaryResult = GetDefinition(word);
                    ShowDefinitions(dictionaryResult);
                }
                catch (WebException)
                {
                    Console.WriteLine("Whoops! I didn't understand! ({0})\r\n" +
                        "If It's a verb, try to put it in base form", word);
                    string misReadWord = dictionary.Word;
                    var result = GetDefinition(misReadWord);
                    ShowDefinitions(result);
                    continue;
                }
            }

            return View("Index", dictionary);

        }

        [ResponseCache(Duration = 0, Location = ResponseCacheLocation.None, NoStore = true)]
        public IActionResult Error()
        {
            return View(new ErrorViewModel { RequestId = Activity.Current?.Id ?? HttpContext.TraceIdentifier });
        }

       
        public static List<DictionaryResult> GetDefinition(string pWord)
        {
            var results = new List<DictionaryResult>();
            WebClient webClient = new WebClient();
            byte[] searchResult = webClient.DownloadData(string.Format("https://api.dictionaryapi.dev/api/v2/entries/en_US/{0}", pWord));
            var serializer = new JsonSerializer();
            using (var stream = new MemoryStream(searchResult))
            using (var reader = new StreamReader(stream))
            using (var jsonReader = new JsonTextReader(reader))
            {
                results = serializer.Deserialize<List<DictionaryResult>>(jsonReader);
            }
            return results;
        }

        public static void ShowDefinitions(List<DictionaryResult> definitions)
        {
            foreach (var result in definitions)
            {
                Console.WriteLine($"Word: {result.Word}");
                foreach (var meaning in result.Meanings)
                {
                    int count = 0;
                    Console.WriteLine($"Part of speech: {meaning.PartOfSpeech} \r\n " +
                        $"Definition: {meaning.Definitions[count].DefinitionOfWord} \r\n " +
                        $"Example: {meaning.Definitions[count].Example} \r\n" +
                        "Synonyms:");

                    for (int synonym = 0; synonym < meaning.Definitions[count].Synonyms.Count; synonym++)
                    {
                        Console.WriteLine(meaning.Definitions[count].Synonyms[synonym]);
                    }
                    Console.WriteLine("--------------------------------------------------------------------------------------------------");
                    count++;
                }
            }
        }


model 

    
    public class DictionaryResult
    {
        [JsonProperty(PropertyName = "word")]
        public string Word { get; set; }
        public List<Meaning> Meanings { get; set; }
    }
    [JsonObject(Id = "meanings")]
    public class Meaning
    {
        [JsonProperty(PropertyName = "partOfSpeech")]
        public string PartOfSpeech { get; set; }
        public List<Definition> Definitions { get; set; }
    }

    public class Definition
    {
        [JsonProperty(PropertyName = "definition")]
        public string DefinitionOfWord { get; set; }
        [JsonProperty(PropertyName = "example")]
        public string Example { get; set; }
        [JsonProperty(PropertyName = "synonyms")]
        public List<string> Synonyms { get; set; }
    }

It's my view 

        @model DictionaryResult
    @using (Html.BeginForm())
    {
        @Html.AntiForgeryToken()
    
    <div class="form-horizontal">
    
        <hr />
        @Html.ValidationSummary(true, "", new { @class = "text-danger" })
        <div class="form-group">
            @Html.LabelFor(model => model.Word)
            <div class="col-md-10">
                @Html.EditorFor(model => model.Word, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.Word, "", new { @class = "text-danger" })
            </div>
        </div>
      
        <div class="form-group mt-4 mb-4">
            <div class="col-md-offset-2 col-md-10">
                <input type="submit" value="Create" class="btn btn-primary" />
            </div>
        </div>
        <div>
    
            <hr />
            <dl class="dl-horizontal">
                <dt>
                    @Html.DisplayNameFor(model => model.Meanings)
                </dt>
    
                <dd>
                    @Html.DisplayFor(model => model.Meanings)
                </dd>
    
            </dl>
        </div>
    
    
    </div>
    }



@Html.DisplayFor(model => model.Meanings) where  the value should be displayed but it is not displayed


result program in console when I entered the word hello

    hello
    Word: hello
    
    Part of speech: exclamation
    
     Definition: used as a greeting or to begin a phone conversation.

"It doesn't work" is probably the most useless problem report we get - and we get it a lot. It tells us nothing about what is happening, or when it happens.
So tell us what it is doing that you didn't expect, or not doing that you did.
Tell us what you did to get it to happen.
Tell us any error messages.

But ... Compiling does not mean your code is right! :laugh:
Think of the development process as writing an email: compiling successfully means that you wrote the email in the right language - English, rather than German for example - not that the email contained the message you wanted to send.

So now you enter the second stage of development (in reality it's the fourth or fifth, but you'll come to the earlier stages later): Testing and Debugging.

Start by looking at what it does do, and how that differs from what you wanted. This is important, because it give you information as to why it's doing it. For example, if a program is intended to let the user enter a number and it doubles it and prints the answer, then if the input / output was like this:
Input   Expected output    Actual output
  1            2                 1
  2            4                 4
  3            6                 9
  4            8                16
Then it's fairly obvious that the problem is with the bit which doubles it - it's not adding itself to itself, or multiplying it by 2, it's multiplying it by itself and returning the square of the input.
So with that, you can look at the code and it's obvious that it's somewhere here:
C#
private int Double(int value)
   {
   return value * value;
   }

Once you have an idea what might be going wrong, start using the debugger to find out why. Put a breakpoint on the first line of the method, and run your app. When it reaches the breakpoint, the debugger will stop, and hand control over to you. You can now run your code line-by-line (called "single stepping") and look at (or even change) variable contents as necessary (heck, you can even change the code and try again if you need to).
Think about what each line in the code should do before you execute it, and compare that to what it actually did when you use the "Step over" button to execute each line in turn. Did it do what you expect? If so, move on to the next line.
If not, why not? How does it differ?
Hopefully, that should help you locate which part of that code has a problem, and what the problem is.
This is a skill, and it's one which is well worth developing as it helps you in the real world as well as in development. And like all skills, it only improves by use!
