C＃窗口用VS创建子窗口创建

Question

假设我有一个基本形式，有一个按钮，当我点击它时，它会打开一个新窗口。 我怎样才能做到这一点？我尝试在按钮点击事件上创建一个新的表单实例，但它给了我一个例外，那就是错误。

Answer 1

Form frm = new Form();
frm.ShowDialog();
//frm.Show();

或者请分享您的代码..

Answer 2

//assuming that ur first form is named Form1 and ur second form is Form2

//assuming that ur button is button1
//inside form1 something like this is shown
Button1.Click +=  new EventHandler(this.Button1_Click);

void Button1_Click(Object sender, EventArgs e){
Form2 form = new Form2();
//you do either
Form2.Show();
//or focus remains on form2 do this
Form2.ShowDialog();
}

//希望这个帮助
