例子一、将字符串转为变量名

        string str = "spp";
        public string spp = "very good";
        private void button1_Click(object sender, EventArgs e)
        {           
            MessageBox.Show(this.GetType().GetField(str).GetValue(this).ToString());
        }

例子二、通过字符串给变量赋值

  public string gisoracle = "ok";

        private void button2_Click(object sender, EventArgs e)
        {

            //通过字符串获得变量值
            MessageBox.Show(this.GetType().GetField("gisoracle").GetValue(this).ToString());
            //通过给变量赋值
            this.GetType().GetField("gisoracle").SetValue(this, "gisoracle@126.com");
            //新的值
            MessageBox.Show(this.GetType().GetField("gisoracle").GetValue(this).ToString());
        }
