Support DTO auto Gen

[vipwan]

nuget add:

dotnet add package Biwen.AutoClassGen.Attributes

Entitys define:

namespace Biwen.AutoClassGen.TestConsole.Entitys
{
    public class User : Info
    {
        /// <summary>
        /// Id
        /// </summary>
        public string Id { get; set; } = null!;
        /// <summary>
        /// first name
        /// </summary>
        public string FirstName { get; set; } = null!;
        /// <summary>
        /// last name
        /// </summary>
        public string LastName { get; set; } = null!;
        /// <summary>
        /// age
        /// </summary>
        public int? Age { get; set; }
        /// <summary>
        /// fullname
        /// </summary>
        public string? FullName => $"{FirstName} {LastName}";
    }
    public abstract class Info : Other
    {
        /// <summary>
        /// email
        /// </summary>
        public string? Email { get; set; }
    }
    public abstract class Other
    {
        /// <summary>
        /// remark
        /// </summary>
        public string? Remark { get; set; }
    }
}

usage :

using Biwen.AutoClassGen.TestConsole.Entitys;
namespace Biwen.AutoClassGen.TestConsole.Dtos
{
    /// <summary>
    /// to be generated
    /// </summary>
    [AutoDto(typeof(User), nameof(User.Id), "TestCol")]
    public partial class UserDto

    /// </summary>
    [AutoDto(typeof(User), nameof(User.Email))]

    /// </summary>
    [AutoDto<User>(nameof(User.Email), "TestCol")]

提供简单的Mapper映射:
auto gen Mapper :

#pragma warning disable
namespace Biwen.AutoClassGen.TestConsole.Entitys
{
    using Biwen.AutoClassGen.TestConsole.Dtos;
    public static partial class UserToUserDtoExtentions
    {
        /// <summary>
        /// mapper to UserDto
        /// </summary>
        /// <returns></returns>
        public static UserDto MapperToDto(this User model)
        {
            return new UserDto()
            {
                FirstName = model.FirstName,
                LastName = model.LastName,
                Age = model.Age,
                FullName = model.FullName,
                Email = model.Email,
                Remark = model.Remark,
            };
        }
    }
}
#pragma warning restore

C#11+(NET7+) 支持使用泛型特性标注(support Generic Attribute)

usage : [AutoDto<T>(params string?[])]

    [AutoDto<User>(nameof(User.Email), "TestCol")]
    public partial class User3Dto
    {
    }

提供MapperToPartial 用于自定义Mapper实现

namespace Biwen.AutoClassGen.TestConsole.Entitys
{
    public static partial class UserToUserDtoExtentions
    {
        static partial void MapperToPartial(User from, UserDto to)
        {
            to.FirstName = "重写了FirstName";
        }
    }
}
