前端js传json对象，c#后端接收

工具类部分

 public T ObjectToEntity<T>(object asObject) where T : new()
        {
            //创建实体对象实例
            var t = Activator.CreateInstance<T>();
            //  user userModel = new UserOperation().ConvertObject<user>(obj);
            IDictionary<string, object> iDictionary = ((IDictionary<string, object>)asObject);
  
            //查找实体类属性是否和object属性相同
            foreach (var info in typeof(T).GetProperties())
            {
                if (iDictionary.ContainsKey(info.Name))
                {
                    //赋值给实体类
                    info.SetValue(t, iDictionary[info.Name], null);
                }
            }
            return t;
        }

调用工具类，注意：使用工具必须创建实体类

 user ss=ObjectToEntity<user>(json);

实体类部分

public class user
    {
        public user()
        {
        }
        //用户名
        public string userName;
        //密码
        public string passWord;
        public string UserName { get => userName; set => userName = value; }
        public string PassWord { get => passWord; set => passWord = value; }
    }
