AutoMapper Mapping Exception #8761 | Support Center

alfar_re created 4 years ago

Hi,

I'm getting this error on the bold line of code below

AutoMapper.AutoMapperMappingException: Missing type map configuration or unsupported mapping.

`public async Task&lt;string&gt; GenerateNumberAsync(ModuleProfile profile, int tenantId)
        {
            var numberFormat = await _numberFormatRepository.GetAll().Where(e => e.Module == profile && e.TenantId == tenantId).FirstOrDefaultAsync();

            long _current = numberFormat.Current;
            int _seed = numberFormat.Seed;
            long _new = _current + _seed;
            long? _total = 1 + numberFormat.Total;
            string _number = string.Concat(numberFormat.Prefix.Trim(), _new.ToString(), numberFormat.Postfix.Trim());
            //
            var newNumberFormat = new NumberFormats.Dtos.GetNumberFormatForViewDto()
            {
         `       NumberFormat = new NumberFormats.Dtos.NumberFormatDto
                {
                    Current = _new,
                    Total = _total,
                }
            };
######             **ObjectMapper.Map(newNumberFormat, numberFormat);**
            //
            return _number;
        }

Hi,

Did you add mapping to CustomDtoMapper.cs for GetNumberFormatForViewDto to NumberFormat ?

Hi,

I added the mapping and it worked. I guess that was the step I was missing. Thanks a gigabyte @ismcagdas.
