How to map class entity within json with automapper?

Question

I am storing the Meta information into String fields. but in DTO object I am mapped with separated class object..

Sample JSON Post object

{

  "name": "string",
  "directionId": 0,
  "description": "string",
  "siteId": 0,
  "zoneId": 0,
  "areaId": 0,
  "metaData": {
    "input": {
      "name": "string",
      "key": "string",
      "agentId": 0,
      "type": 0
    },
    "outPut": {
      "name": "string",
      "key": "string",
      "agentId": 0,
      "type": 0
    },
    "position": {
      "lat": "string",
      "long": "string"
    }
  }
}

Entity Class object

/// <summary>
/// SRC  
/// </summary>
public class SRC
{
    public int Id { get; set; }
    public string Name { get; set; }
    public int? DirectionId { get; set; }
    public string Description { get; set; }
    public int? SiteId { get; set; }
    public int? ZoneId { get; set; }
    public int? AreaId { get; set; }

    /// <summary>
    /// Json view MetaData
    /// { 
    ///   "input": {
    ///      name:"my input1",
    ///       key:"43434",
    ///       agent:"1",
    ///       type:"1",
    ///    }
    ///    "output": {
    ///      name:"my output",
    ///       key:"12333",
    ///       agent:"1",
    ///       type:"1",
    ///    }
    ///    "position": {
    ///      lat:"42°21'30"N 71°03'37",
    ///       long:"42°21'30"S 71°03'37",
    ///    }
    /// }
    /// </summary>
    public string MetaData { get; set; }
}

DTO Class object

/// <summary>
/// SRC DTO
/// </summary>
public class SrcDTO
{
    public int Id { get; set; }
    public string Name { get; set; }
    public int? DirectionId { get; set; }
    public string Description { get; set; }
    public int? SiteId { get; set; }
    public int? ZoneId { get; set; }
    public int? AreaId { get; set; }
    [JsonProperty("MetaData")]
    public SourceMetaData MetaData { get; set; }
}
#region Meta Data Class

public class SRCMetaData
{
    [JsonProperty("Input")]
    SourceInput SourceInput { get; set; }
    [JsonProperty("OutPut")]
    SourceOutput SourceOutput { get; set; }
    [JsonProperty("Position")]
    SourcePosition SourcePosition { get; set; }
}
public class SourceInput
{
    public string Name { get; set; }
    public string Key { get; set; }
    public int AgentId { get; set; }
    public int Type { get; set; }
}
public class SourceOutput
{
    public string Name { get; set; }
    public string Key { get; set; }
    public int AgentId { get; set; }
    public int Type { get; set; }
}
public class SourcePosition
{
    public string Lat { get; set; }
    public string Long { get; set; }
}
#endregion

How it will mapped with Auto Mapper profile?

   CreateMap<SrcDTO, Src>()
        .ForMember(x => x.MetaData, cfg => { cfg.MapFrom(jo => JsonConvert.SerializeObject(jo.MetaData)); })
        ;

        CreateMap<Src,  SrcDTO>()
        .ForMember(x=>x.MetaData , cfg => { cfg.MapFrom(jo => JsonConvert.DeserializeObject(jo.MetaData)); })
        ;

On post action with sending JSON it's working ok. but in the GetALL action its not working see below images for references.

Issue was mapping "Int" data type fields in sub class object. I have been fixed by modifying with "string" data type fields.

As serialized with JsonConvert.SerializeObject with casting then it worked for me..

Thank you.
