反射获取属性及对应值示例

public abstract class MyBase
    {
        public virtual string GetParams()
        {
            var list = new List<string>();
            var t = this.GetType();
            var members = t.GetProperties();
            foreach (PropertyInfo m in members)
            {
                list.Add(m.Name + "=" + m.GetValue(this, null).ToString());
            }
            return string.Join("&", list);
        }
    }

    public class A : MyBase
    {
        public string Param1 { get; set; }
        public string Param2 { get; set; }
        public string Param3 { get; set; }
    }

调用方法：

A a = new A();
                a.Param1 = "A1";
                a.Param2 = "A2";
                a.Param3 = "A3";
                var p = a.GetParams();
                Console.WriteLine(p);
