创建Helper

csharp 复制代码

using System;
using System.Collections.Generic;
using System.Globalization;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace dicToObj
{
    internal class Helper
    {
        /// <summary>
        /// 字典类型转化为对象
        /// </summary>
        /// <param name="dic"></param>
        /// <returns></returns>
        public T DicToObject<T>(Dictionary<string, object> dic) where T : new()
        {
            var md = new T();
            CultureInfo cultureInfo = Thread.CurrentThread.CurrentCulture;
            TextInfo textInfo = cultureInfo.TextInfo;
            foreach (var d in dic)
            {
                var filed = textInfo.ToTitleCase(d.Key);
                try
                {
                    var value = d.Value;
                    md.GetType().GetProperty(filed).SetValue(md, value);
                }
                catch (Exception e)
                {

                }
            }
            return md;
        }
    }
}

使用演示

csharp 复制代码

using dicToObj;

var dic = new Dictionary<string, object>()
{
    {"name", "Tom"},
    {"age", 25},
    {"address", "Beijing"}
};

Helper helper = new Helper();
var person = helper.DicToObject<Person>(dic);


Console.WriteLine(person);
Console.WriteLine();

public record Person
{
    public string Name { get; set; }
    public int Age { get; set; }
    public string Address { get; set; }
}

补充

但是上述方法无法将字典转化为object，可以使用序列化巧妙转化

csharp 复制代码

 public static object DicToObj(Dictionary<string, object> dictionary)
    {
        string json = JsonConvert.SerializeObject(dictionary);
        return JsonConvert.DeserializeObject<object>(json);
    }
