Comma delimited string AutoMapper

Without knowing too many details, it seems to me that there are two ways to achieve this, given the following DTO we want to populate:

public class DTO 
{
    public string FirstName { get;set; }
    public string LastName { get;set; }
}

      

        
        
        
      

    

and sample input:

string input = "Andrew,Whitaker";

      

        
        
        
      

    

• Write a custom type converter (recommended):

  public class CommaDelimitedStringConverter : TypeConverter<string, DTO>
  {
      protected override DTO ConvertCore(string source)
      {
          string[] tokens = source.Split(',');
  
          DTO result = null;
  
          if (tokens.Length == 2) 
          {        
              result = new DTO();
              result.FirstName = tokens[0];
              result.LastName = tokens[1];
          }
          return result;
      }
  }
  
  Mapper.CreateMap<string, DTO>()
      .ConvertUsing<CommaDelimitedStringConverter>();
  
        
  
          
          
          
        
  
      

• Match each property to one-off (not recommended unless it's quick and dirty):

  Mapper.CreateMap<string, DTO>()
      .ForMember(dest => dest.FirstName, opt => opt.MapFrom(src => src.Split(',')[0]))
      .ForMember(dest => dest.LastName, opt => opt.MapFrom(src => src.Split(',')[1]));
