C# 获取实体类的字段名称和值

//  设置Dictionary<string, string> 得到实体类的字段名称和值

        public static Dictionary<string, string> GetProperties<T>(T t)
        {
            Dictionary<string, string> ret = new Dictionary<string, string>();

            if (t == null)
            {
                return null;
            }
            System.Reflection.PropertyInfo[] properties = t.GetType().GetProperties(System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.Public);

            if (properties.Length <= 0)
            {
                return null;
            }
            foreach (System.Reflection.PropertyInfo item in properties)
            {
                string name = item.Name;                                                  //实体类字段名称
                string value = ObjToStr(item.GetValue(t, null));                //该字段的值
                
                if (item.PropertyType.IsValueType || item.PropertyType.Name.StartsWith("String"))
                {
                        ret.Add(name, value);        //在此可转换value的类型
                }
            }

            return ret;
        }


 

//反过来根据Dictionary来设置实体类

        public static T SetProperties<T>(T t, Dictionary<string, string> d)
        {

            }
            foreach (System.Reflection.PropertyInfo item in properties)
            {
                string name = item.Name;                                         //名称
                string value = ObjToStr(item.GetValue(t, null));       //值

                if (item.PropertyType.IsValueType || item.PropertyType.Name.StartsWith("String"))
                {
                    string val = d.Where(c => c.Key == name).FirstOrDefault().Value;
