Question

I am working in MVC4 and want to define a model using an Uppercase attribute. The idea would be that the presence of the Uppercase attribute would cause the mod

Answer 1

For Web API purpose it is better to convert the incoming json to uppercase or lowercase.

    public class ToUpperCase : JsonConverter
    {
        public override bool CanConvert(Type objectType)
        {
            return objectType == typeof(string);
        }

        public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
        {
            return reader.Value.ToString().ToUpper();
        }            
    }



    [Display(Name = "PNR NAME")]
    [JsonConverter(typeof(Annotations.ToUpperCase))]
    public string PNR { get; set; }

OR Globally;

  protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();
        //.......... others



        JsonMediaTypeFormatter jsonFormatter = GlobalConfiguration.Configuration.Formatters.JsonFormatter;
        JsonSerializerSettings jSettings = new Newtonsoft.Json.JsonSerializerSettings();
        jSettings.Converters.Add(new UpperCaseStringConverter());
        jsonFormatter.SerializerSettings = jSettings;
    }
