C# 字符串轉為變量名，通過字符串給變量賦值

例子一、將字符串轉為變量名

        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、通過字符串給變量賦值

 

  public string gisoracle = "ok";

        private void button2_Click(object sender, EventArgs e)
        {

            //通過字符串獲得變量值
            MessageBox.Show(this.GetType().GetField("gisoracle").GetValue(this).ToString());
            //通過給變量賦值
            this.GetType().GetField("gisoracle").SetValue(this, "[e-mail]");
            //新的值
            MessageBox.Show(this.GetType().GetField("gisoracle").GetValue(this).ToString());
        }
