C#通过反射获取相应的字段和值

代码比较简单，只作为简单的例子参考

首先先看运行的代码：

 class Program
    {
        static void Main(string[] args)
        {
            UserInfo userInfo = new UserInfo();
            userInfo.ID = 1;
            userInfo.Name = "bailey";
            userInfo.CreateDate = DateTime.Now;
            userInfo.Number = Convert.ToDecimal(456.6467);

            string values = string.Empty;
            foreach (System.Reflection.PropertyInfo p in userInfo.GetType().GetProperties())
            {
                if (p.PropertyType == typeof(string))
                {
                    values += string.Format("{0}='{1}', ", p.Name, p.GetValue(userInfo));
                }
                if (p.PropertyType == typeof(int)|| p.PropertyType == typeof(uint))
                {
                    values += string.Format("{0}={1},", p.Name, p.GetValue(userInfo));
                }
                if (p.PropertyType == typeof(DateTime))
                {
                    values += string.Format("{0}='{1}', ", p.Name, p.GetValue(userInfo));
                }
                if (p.PropertyType == typeof(decimal) || p.PropertyType == typeof(double)|| p.PropertyType == typeof(float))
                {
                    values += string.Format("{0}={1}, ", p.Name, p.GetValue(userInfo));
                }
               
                if (p.PropertyType == typeof(bool))
                {
                    values += string.Format("{0}={1}, ", p.Name, p.GetValue(userInfo));
                }
                if (p.PropertyType == typeof(sbyte))
                {
                    values += string.Format("{0}={1}, ", p.Name, p.GetValue(userInfo));
                }
                if (p.PropertyType == typeof(byte) || p.PropertyType == typeof(short) || p.PropertyType == typeof(ushort) )
                {
                    values += string.Format("{0}={1}, ", p.Name, p.GetValue(userInfo));
                }
                if (p.PropertyType == typeof(long) || p.PropertyType == typeof(ulong))
                {
                    values += string.Format("{0}={1}, ", p.Name, p.GetValue(userInfo));
                }

                // values +=string.Format( "{0}={1},", p.Name, p.GetValue(userInfo));
                // Console.WriteLine("Name:{0} Value:{1}", p.Name, p.GetValue(userInfo));
            }
            Console.WriteLine(values);
            Console.ReadLine();
        }

    }

再看对象：

 class UserInfo {
        public int ID { get; set; }
        public string Name { get; set; }
        public DateTime? CreateDate { get; set; }
        public decimal? Number { get; set; }
        public bool IsUse { get; set; }
    }
