Q:Form1上一个Button点击后弹出新窗口Form2,在新窗口点击Button如何控制Form1中的某些控件? A:用委托。一个简单可行的办法用ref.下面是个小例子: 在Form1的button1_Click里写: private void button1_Click(object sender, EventArgs e) { this.button1.Enabled = false; Form2 f2 = new Form2(ref button1); f2.Show(); } Form2里这样写: public Button button; public Form2(ref Button button) { this.button = button; InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { this.button.Enabled = true; }
