Size、Location属性需要new，而其他不需要

单击菜单项的menuItem事件后，状态面板中显示相应的窗体尺寸信息

this.toolStripStatusLabel1.Text= "大窗体";

 private void Form1_Load(object sender, EventArgs e)
        {
            this.Size = new Size(300, 200);
        }

        private void toolStripMenuItem1_Click(object sender, EventArgs e)
        {
            this.Size = new Size(600, 400);
            this.toolStripStatusLabel1.Text= "大窗体";
        }

        private void toolStripMenuItem2_Click(object sender, EventArgs e)
        {
            this.Size = new Size(300, 200);
            this.toolStripStatusLabel1.Text = "中窗体";
        }

        private void toolStripMenuItem3_Click(object sender, EventArgs e)
        {
            this.Size = new Size(150, 120);
