  Hi,
  
  For generic filtering of external system i need to get source path of mapping by destination path.
  
  
                  CreateMap<Record, Contact>()
                  .ForMember(x => x.Id, opt => opt.MapFrom(c => c.Id))
                  .ForMember(x => x.PersonInformation, opt => opt.MapFrom(c=>
                      new PersonInformation()
                      {                        
                          FirstName = c.FirstName,
                          LastName = c.LastName,
                          MiddleName = c.MiddleName,
                          ExternalReferences = new List<ExternalReference>() { new ExternalReference { Id = 1, Ref = c.Id } }
                      }
                  ))
  
  I created function but it works only for simple paths like:
  Contact.Id => Record.Id
  but it dont work with
  Contact.PersonInformation.FirstName =will be mapped to> Record.FirstName
  
          public (PropertyInfo propertyInfo, string path) GetDestinationPropertyFor(string sourcePropertyPath, Type salesforceType, Type swaggerType)
          {
              var properties = sourcePropertyPath.Split('.');
              var destinationProperties = new List<string>();
              PropertyInfo propertyInfo = null;
  
  
              foreach (var property in properties)
              {
                  var map = _mapper.FindTypeMapFor(salesforceType, swaggerType);
                  var propertyMap = map.PropertyMaps.First(pm => pm.DestinationMember == swaggerType.GetProperty(property));
  
  
                  propertyInfo = propertyMap.SourceMember as PropertyInfo;
  
  
                  var jsonProperty = propertyInfo.GetCustomAttribute(typeof(JsonPropertyAttribute));
                  destinationProperties.Add(((JsonPropertyAttribute)jsonProperty).PropertyName);
  
  
                  swaggerType = propertyMap.Types.DestinationType;
                  salesforceType = propertyMap.Types.SourceType;
              }
  
  
              var destinationPropertyPath = string.Join('.', destinationProperties);
  
  
              return (propertyInfo, destinationPropertyPath);
          }
