PocoEmit字典增强功能
一、PocoEmit集合扩展中支持字典[*]支持字典互转
[*]支持数组转字典(索引转化为字典主键)
[*]支持列表转字典(索引转化为字典主键)
默认集合功能不支持实体属性转字典
为此开发了以下字典增强功能来实现实体转字典
二、实体和字典互转
1. ToDictionary
实体成员转化为object字典
User user = new() { Id = 3, Name = "张三" };
IDictionary<string, object> dic = _mapper.ToDictionary(user);2. GetToDictionaryFunc
实体成员转化为object字典
var func = _mapper.GetToDictionaryFunc<User>();
User user = new() { Id = 3, Name = "张三" };
IDictionary<string, object> dic = func(user);3. FromDictionary
object字典转化为实体
Dictionary<string, object> dic = new() { { nameof(User.Id), "3" }, { nameof(User.Name), "张三" } };
User user = _mapper.FromDictionary<User>(dic);4. GetFromDictionaryFunc
object字典转化为实体
var func = _mapper.GetFromDictionaryFunc<User>();
Dictionary<string, object> dic = new() { { nameof(User.Id), "3" }, { nameof(User.Name), "张三" } };
User user = func(dic);三、实体属性平铺
1. CreateDictionaryConvertFunc
[*]委托编译生成,重复使用需要缓存
[*]递归转化指定类型成员为字典
[*]支持同类型字典
[*]不支持数组和其他集合
[*]相当于彻底平铺展开
var func = _mapper.CreateDictionaryConvertFunc<Student, Dictionary<string, int>>();
Student source = new()
{
User = new() { Id = 2, Name = "Jxj" },
Age = 17,
Score = new() { { "语文", 95 }, { "数学", 96 } }
};
Dictionary<string, int> result = func(source);
// result.Count == 46. CreateDictionaryConvertFunc重载方法
[*]委托编译生成,重复使用需要缓存
[*]递归转化指定类型成员为字典
[*]支持同类型字典
[*]不支持数组和其他集合
[*]相当于彻底平铺展开
var func = _mapper.CreateDictionaryConvertFunc<Student, int, IDictionary<string, string>>();
Student source = new()
{
User = new() { Id = 2, Name = "Jxj" },
Age = 17,
Scores = new() { { "语文", 95 }, { "数学", 96 } }
};
IDictionary<string, string> result = func(source);
// result.Count == 4源码托管地址: https://github.com/donetsoftwork/MyEmit ，也欢迎大家直接查看源码。
