Question

but not able to serialize the enum to string values. Only integer values are displayed in the swagger page. Could some please help me how to fix this?.

Answer 1

You have several ways to achieve this.

• Add the [JsonConverter(typeof(StringEnumConverter))] attribute on the Enum field.

  using Newtonsoft.Json;
  using Newtonsoft.Json.Converters;
  
  [JsonConverter(typeof(StringEnumConverter))]
  public Gender Gender { get; set; }
  

• Add formatting parameter during serialization.

  string value = JsonConvert.SerializeObject(objectlist,new Newtonsoft.Json.Converters.StringEnumConverter());
