c# - Automapper multiple memberOptions -

i have viewmodel needs data 2 collections. 2 collections members of indicatiestelling. map pass instance of indicatiestelling.

each property uses valueresolver gets right value out of given collection. make work need register valueresolver each property , source each property. tried this:

mapper.createmap<model.indicatiestelling, clientrechtmatigheiddto>()                 .formember(dest => dest.hasfactbeoordelenrechtmatigheid, (opt) => { opt.resolveusing<indicatiestellingfactvalueresolver>(); opt.mapfrom(src => src.indicatiestellingfacts); })                 .formember(dest => dest.hasfactrechtmatig, (opt) => { opt.resolveusing<indicatiestellingfactvalueresolver>(); opt.mapfrom(src => src.indicatiestellingfacts); })                 .formember(dest => dest.soortvoorziening, (opt) => { opt.resolveusing<indicatiestellinganswervalueresolver>(); opt.mapfrom(src => src.indicatiestellinganswer); })                 .formember(dest => dest.zzp, (opt) => { opt.resolveusing<indicatiestellinganswervalueresolver>(); opt.mapfrom(src => src.indicatiestellinganswer); }); 

this code doesn't work, still mapping errors:

missing type map configuration or unsupported mapping.

mapping types: hashset`1 -> boolean

i searched example/docs using multiple member options, nothing came up. supported? , ifso, doing wrong here?

i don't think can combined in way want, little refactoring can use this:

mapper.createmap<model.indicatiestelling, clientrechtmatigheiddto>()     .formember(dest => dest.hasfactbeoordelenrechtmatigheid, opt => opt.resolveusing(src => indicatiestellingfactvalueresolver.resolve(src.indicatiestellingfacts)))     .formember(dest => dest.hasfactrechtmatig, opt => opt.resolveusing(src => indicatiestellingfactvalueresolver.resolve(src.indicatiestellingfacts)))     .formember(dest => dest.soortvoorziening, opt => opt.resolveusing(src => indicatiestellinganswervalueresolver.resolve(src.indicatiestellinganswer)))     .formember(dest => dest.zzp, opt => opt.resolveusing(src => indicatiestellinganswervalueresolver.resolve(src.indicatiestellinganswer))); 

(i refactored ivalueresolvers static methods)

or can make ivalueresolvers know member at, e.g. hardcoded:

public class indicatiestellingfactvalueresolver : ivalueresolver {     public resolutionresult resolve(resolutionresult source)     {         var model = (model.indicatiestelling)source.value;         var obj = model.indicatiestellingfacts;         // calculate obj     } }  mapper.createmap<model.indicatiestelling, clientrechtmatigheiddto>()     .formember(dest => dest.hasfactbeoordelenrechtmatigheid, opt => opt.resolveusing<indicatiestellingfactvalueresolver<model.indicatiestelling>>())     // etc 

or using func:

public class indicatiestellingfactvalueresolver<tsource> : ivalueresolver {     private func<tsource, object> selector;     public indicatiestellingfactvalueresolver(func<tsource, object> selector)     {         this.selector = selector;     }     public resolutionresult resolve(resolutionresult source)     {         var model = (tsource)source.value;         object obj = selector(model);         // calculate obj     } }  mapper.createmap<model.indicatiestelling, clientrechtmatigheiddto>()     .formember(dest => dest.hasfactbeoordelenrechtmatigheid,     opt => opt.resolveusing<indicatiestellingfactvalueresolver<model.indicatiestelling>>()                 .constructedby(() => new indicatiestellingfactvalueresolver<model.indicatiestelling>(x => x.indicatiestellingfacts)))     // etc
