AutoMapper property name conversions -

i'm trying register mapping convention handle mapping classes pascal case names classes underscore names postfix , prefix, , again. i've tried follow examples, cannot head around how it's supposed work.

this 1 of many things i've tried, looks should work (in opinion :)), doesn't seem anything:

public class pascalcaseentity {     public string callingsystem { get; set; } }  public class underscorewithprefixandpostfixentity {     public string p_calling_system_ { get; set; } }  public class partsmappings {     public void apply()     {         mapper.initialize(cfg =>         {             cfg.addprofile<fromunderscoremapping>();             cfg.addprofile<tounderscoremapping>();              cfg.createmap<pascalcaseentity, underscorewithprefixandpostfixentity>()                   .withprofile("tounderscoremapping");             cfg.createmap<underscorewithprefixandpostfixentity, pascalcaseentity>()                   .withprofile("fromunderscoremapping");         });     } }  public class fromunderscoremapping : profile {     protected override void configure()     {         recognizeprefixes("p_");         recognizepostfixes("_");         sourcemembernamingconvention = new lowerunderscorenamingconvention();         destinationmembernamingconvention = new pascalcasenamingconvention();     }      public override string profilename     {         { return "fromunderscoremapping"; }     } }  public class tounderscoremapping : profile {     protected override void configure()     {         recognizedestinationprefixes("p_");         recognizedestinationpostfixes("_");         sourcemembernamingconvention = new pascalcasenamingconvention();         destinationmembernamingconvention = new lowerunderscorenamingconvention();     }      public override string profilename     {         { return "tounderscoremapping"; }     } } 

what missing here?

i found working solution. created 2 profiles, 1 each "direction", , added mappings them.

i'm not happy it, since i'd rather have mappings in same file (grouping them on business area). @ least works... :)

i tried putting registrations in same profile, , using .withprofile("tounderscorewithprefix") method, didn't work.

mapper.initialize(cfg => {     cfg.addprofile(new tounderscorewithprefixmappings());     cfg.addprofile(new fromunderscorewithprefixmappings()); });  public class tounderscorewithprefixmappings : profile {     protected override void configure()     {         recognizedestinationprefixes("p", "p");          sourcemembernamingconvention = new pascalcasenamingconvention();         destinationmembernamingconvention = new lowerunderscorenamingconvention();          createmap<pascalcaseentity, underscorewithprefixandpostfixentity>();     }      public override string profilename { get; } = "tounderscorewithprefix"; }  public class fromunderscorewithprefixmappings : profile {     protected override void configure()     {         recognizeprefixes("p_", "p_");         recognizepostfixes("_");          sourcemembernamingconvention = new lowerunderscorenamingconvention();         destinationmembernamingconvention = new pascalcasenamingconvention();          createmap<underscorewithprefixandpostfixentity, pascalcaseentity>();     }      public override string profilename { get; } = "fromunderscorewithprefix"; }
