[原创]C#里的狸猫换太子ref，out

        void ThisRef(ref int i)
        {
            i = 100;
        }

        void ThisOut(out int j)
        {
            j = 99;
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            int i = 0;
            ThisRef(ref i);
            label1.Text = i.ToString();

            int j;
            ThisOut(out j);
            label2.Text = j.ToString();
        }
