C# AutoMapper map issue with Upper Case Under Score

Question

I have an issue with uppercase underscore mappings.

Data Class have property like => USER_ID

Dto class property => UserId

If a change it to Userİd it's working.

How could i do mapping without formember method ? Thanks

My initializer :

 cfg.SourceMemberNamingConvention = new LowerUnderscoreNamingConvention();
 cfg.DestinationMemberNamingConvention = new PascalCaseNamingConvention();   

Edit:

I solved it for now. It worked for USER_ID => UserId

Main topic : Automapper: How to leverage a custom INamingConvention?

Solution with basic if :

public class UpperUnderscoreNamingConvention : INamingConvention
{
    private readonly Regex _splittingExpression = new Regex(@"[\p{Lu}0-9]+(?=_?)");

    public Regex SplittingExpression { get { return _splittingExpression; } }

    public string SeparatorCharacter { get { return "_"; } }

    public string ReplaceValue(Match match)
    {
       return match.Value.Equals("I") ? "ı" : match.Value.ToLowerInvariant();           
    }
}

config :

Mapper.Initialize(cfg =>
        {

            cfg.SourceMemberNamingConvention = new UpperUnderscoreNamingConvention();
            cfg.DestinationMemberNamingConvention = new PascalCaseNamingConvention();                


        });
