Configure AutoMapper to know what types you want to map
var configuration = new MapperConfiguration(cfg =>
{
cfg.CreateMap<retailer, RAccountDetail>();
});
Validate your mappings (remove it before release)
configuration.AssertConfigurationIsValid();
Create the mapper
var mapper = configuration.CreateMapper();
Execute the mappings:
var retailerAccount = mapper.Map<retailer, RAccountDetail>(retailModel);
Example
// Map BankModel(source) to Bank (destination)
public void CreateBank(BankModel bankModel)
{
var config = new MapperConfiguration(cfg => cfg.CreateMap<BankModel, Bank>());
var mapper = config.CreateMapper();
var bank = mapper.Map<BankModel, Bank>(bankModel);
service.CreateBank(bank);
}
// Map Bank (source) to BankModel (destination)
public BankModel ReadBank(int ID)
{
var config = new MapperConfiguration(cfg => cfg.CreateMap<Bank, BankModel>());
var mapper = config.CreateMapper();
var bank = service.ReadBank(ID);
return mapper.Map<Bank, BankModel>(bank);
}
