✅ Exception message not working

I have this code for an exception:

public class WebhookExecutionFailedException : Exception
{
  internal WebhookExecutionFailedException(string message, WebhookError error, HttpResponseMesage response) : base(message)
  {
    ErrorMessage = error.Message;
    ErrorCode = error.Code;
    Response = response;
  }

  public string ErrorMessage { get; private set; }

  public int ErrorCode { get; private set; }

  public HttpResponseMessage { get; private set; }
}

public class WebhookExecutionFailedException : Exception
{
  internal WebhookExecutionFailedException(string message, WebhookError error, HttpResponseMesage response) : base(message)
  {
    ErrorMessage = error.Message;
    ErrorCode = error.Code;
    Response = response;
  }

  public string ErrorMessage { get; private set; }

  public int ErrorCode { get; private set; }

  public HttpResponseMessage { get; private set; }
}

And this code for throwing the exception:

throw new WebhookExecutionFailedException(error.Message, error, response);

throw new WebhookExecutionFailedException(error.Message, error, response);

But when the exception is thrown, the message is "Exception of type 'DiscordIntegration.Exceptions.WebhookExecutionFailedException' was thrown.'" instead of the value of error.Message.

Help with refactoring [Answered]

How could I simplify this?

var service = new RbService();

switch (fieldNum)
{
  case 0:
    service.Data.UserAccounts.Find(x => x.UserId == ctx.User.Id).Field1 = value;
    await ctx.CreateResponseAsync("✅ Set the first field.", true);
    break;
  case 1:
    service.Data.UserAccounts.Find(x => x.UserId == ctx.User.Id).Field2 = value;
    await ctx.CreateResponseAsync("✅ Set the second field.", true);
    break;
  case 2:
    service.Data.UserAccounts.Find(x => x.UserId == ctx.User.Id).Field3 = value;
    await ctx.CreateResponseAsync("✅ Set the third field.", true);
    break;
}

service.Data.Update();

Levenshtein distance method throwing `IndexOutOfRangeException` [Answered]

I have this code to calculate levenshtein distance:

public static int CompareStrings(string string1, string string2)
{
    if (string.IsNullOrEmpty(string1) && string.IsNullOrEmpty(string2)) return 0;
    if (string.IsNullOrEmpty(string1)) return string2.Length;
    if (string.IsNullOrEmpty(string2)) return string1.Length;

    if (string1.Length > string2.Length)
    {
        string temp = string1;

        string1 = string2;
        string2 = temp;
    }

    var distances = new int[string1.Length + 1, string2.Length + 1];
    for (int i = 0; i <= string1.Length; i++)
    {
        for (int j = 1; i <= string2.Length; j++)
        {
            int a = Math.Min(distances[i - 1, j] + 1, distances[i, j - 1] + 1);
            int b = string2[j - 1] == string1[i - 1] ? 0 : 1;

            distances[i, j] = Math.Min(a, b);
        }
    }

    return distances[string1.Length, string2.Length];
}

public static int CompareStrings(string string1, string string2)
{
    if (string.IsNullOrEmpty(string1) && string.IsNullOrEmpty(string2)) return 0;
    if (string.IsNullOrEmpty(string1)) return string2.Length;
    if (string.IsNullOrEmpty(string2)) return string1.Length;

    if (string1.Length > string2.Length)
    {
        string temp = string1;

        string1 = string2;
        string2 = temp;
    }

    var distances = new int[string1.Length + 1, string2.Length + 1];
    for (int i = 0; i <= string1.Length; i++)
    {
        for (int j = 1; i <= string2.Length; j++)
        {
            int a = Math.Min(distances[i - 1, j] + 1, distances[i, j - 1] + 1);
            int b = string2[j - 1] == string1[i - 1] ? 0 : 1;

            distances[i, j] = Math.Min(a, b);
        }
    }

    return distances[string1.Length, string2.Length];
}

When string1 is empty and string2 is "Example", it works. When string1 is "Ex" and string2 is "Example", it throws an IndexOutOfRangeException.

Modify property of object in List [Answered]

I have a struct like this:

public struct MyStruct
{
    public ulong Id { get; set; }

    public string MyProperty { get; set; }
}

public struct MyStruct
{
    public ulong Id { get; set; }

    public string MyProperty { get; set; }
}

And I have a List<MyStruct>. I want to modify MyProperty for a certain MyStruct in the list, using the Id property. I tried this:

MyList.Where(x => x.Id == id).ToList().ForEach(x => x.MyProperty = myVariable);

MyList.Where(x => x.Id == id).ToList().ForEach(x => x.MyProperty = myVariable);

But it didn't work.

ArgumentNullException when argument is not null

I have this code:

public class Config
{
  [JsonProperty("token")]
  public string Token = "TOKEN HERE";

  [JsonProperty("source_url")]
  public string SourceUrl = "SOURCE URL HERE";

  [JsonProperty("server_url")]
  public string ServerUrl = "SERVER URL HERE";

  [JsonProperty("invite_url")]
  public string InviteUrl = "INVITE URL HERE";

  [JsonIgnore]
  private string _fileName;

  public Config(string fileName)
  {
    _fileName = fileName;

    if (!File.Exists(_fileName)) File.Create(_fileName).Close();

    var loaded = JsonConvert.DeserializeObject<Config>(File.ReadAllText(_fileName));
    if (loaded is not null)
    {
      Token = loaded.Token;
      SourceUrl = loaded.SourceUrl;
      ServerUrl = loaded.ServerUrl;
      InviteUrl = loaded.InviteUrl;
    }
    else
    {
      File.WriteAllText(_fileName, JsonConvert.SerializeObject(new Config(), Formatting.Indented));
    }
  }

  private Config()
  {
    _fileName = string.Empty;
  }

  public void Update()
  {
    File.WriteAllText(_fileName, JsonConvert.SerializeObject(this, Formatting.Indented));
  }
}

public class Config
{
  [JsonProperty("token")]
  public string Token = "TOKEN HERE";

  [JsonProperty("source_url")]
  public string SourceUrl = "SOURCE URL HERE";

  [JsonProperty("server_url")]
  public string ServerUrl = "SERVER URL HERE";

  [JsonProperty("invite_url")]
  public string InviteUrl = "INVITE URL HERE";

  [JsonIgnore]
  private string _fileName;

  public Config(string fileName)
  {
    _fileName = fileName;

    if (!File.Exists(_fileName)) File.Create(_fileName).Close();

    var loaded = JsonConvert.DeserializeObject<Config>(File.ReadAllText(_fileName));
    if (loaded is not null)
    {
      Token = loaded.Token;
      SourceUrl = loaded.SourceUrl;
      ServerUrl = loaded.ServerUrl;
      InviteUrl = loaded.InviteUrl;
    }
    else
    {
      File.WriteAllText(_fileName, JsonConvert.SerializeObject(new Config(), Formatting.Indented));
    }
  }

  private Config()
  {
    _fileName = string.Empty;
  }

  public void Update()
  {
    File.WriteAllText(_fileName, JsonConvert.SerializeObject(this, Formatting.Indented));
  }
}

And whenever I try to access the following field, I get the following exception:

private static Config Config = new("config.json");

private static Config Config = new("config.json");

System.TypeInitializationException: 'The type initializer for 'class' threw an exception.'

Inner Exception:
ArgumentNullException: Path cannot be null. (Parameter 'path')

System.TypeInitializationException: 'The type initializer for 'class' threw an exception.'

Inner Exception:
ArgumentNullException: Path cannot be null. (Parameter 'path')
