推荐答案

更改它:将处理程序移到form1中: Form1按钮单击事件: Change it: move the handler into form1: Form1 button click event: Form2 f = new Form2(); f.FormClosing += new FormClosingEventHandler(Form2_FormClosing); myButton.Enabled = false; f.Show();

然后将处理程序添加到Form1:

Then add the handler to Form1:

void Form2_FormClosing(object sender, FormClosingEventArgs e) { myButton.Enabled = true; }
