比较两个object对象属性不同

        private string objtostr(object obj)
        {
            if (obj == null) return "None";
            return obj.ToString();
        }
        private void compare(object a1, object a2)
        {

            List<string> pList = new List<string>();

            foreach (System.Reflection.PropertyInfo p in a1.GetType().GetProperties())
            {
                string objname = p.Name;

                string value1 = objtostr(p.GetValue(a1));
                string value2 = getValue(a2, objname);
                if (value1 != value2)
                {

                    pList.Add(string.Format("属性:{0} Value:{1}!={2}", objname, value1, value2));
                }
            }
            ylbasicpub.YLCover.write(@"e:\1.txt", pList);
        }

        private string getValue(object t, string name)
        {
            return objtostr(t.GetType().GetProperty(name).GetValue(t, null));
        }
        private void button1_Click(object sender, EventArgs e)
        {
            compare(button1, button2);
        }
