c# - Automapper，INamingConvention Camelcase 属性为带下划线的大写

Question

我有两个类，一个由 Entity Framework 生成，另一个是我在任何地方都使用的类。

我的类(class):

public class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

EF 类:

public class PERSON
{
    public string FIRST_NAME { get; set; }
    public string LAST_NAME { get; set; }
}

当源是 PERSON 到 Person 时，我找到了解决方案，但是我没有找到 Person< 的解决方案 到 PERSON(属性以大写和下划线分隔)。

The solution for PERSON to Person :

Mapper.Initialize(x => x.AddProfile<Profile1>());
var res = Mapper.Map<PERSON, Person>(person);

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 class Profile1 : Profile
{
    protected override void Configure()
    {
        SourceMemberNamingConvention = new UpperUnderscoreNamingConvention();
        DestinationMemberNamingConvention = new PascalCaseNamingConvention();
        CreateMap<PERSON, Person>();
    }
}

这适用于 AutoMapper 7.0.1 版:

using AutoMapper;
using System.Text.RegularExpressions;


namespace Data.Service.Mapping
{
    public class UpperUnderscoreNamingConvention: INamingConvention
    {
        public Regex SplittingExpression { get; } = new Regex(@"[\p{Ll}\p{Lu}0-9]+(?=_?)");

        public string SeparatorCharacter => "_";

        public string ReplaceValue(Match match) => match.Value.ToUpper();
    }
}
