using VkNet.Enums.Filters; using VkNet.Exception; using VkNet.Model.RequestParams; using VkNet; var api = new VkApi(); api.Authorize(new ApiAuthParams { AccessToken = "access_token" }); try { var userInfo = api.Users.Get(new UsersGetParams { Fields = ProfileFields.All }); } catch (VkApiException ex) { VkErrors.IfErrorThrowException(ex); }In this example, IfErrorThrowException is called within the catch block, passing the VkApiException object as its parameter. If an error occurred during the API call, the exception will be thrown, and the developer can handle the error accordingly. In conclusion, VkErrors is a useful package library for C# developers working with VK API, providing various methods to handle exceptions that may occur during the API calls.
