推荐答案
这样做:
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
e.Cancel = true;
}
为了回应 pix0rs 的担忧 - 是的,您将无法以编程方式关闭应用程序是正确的.但是,您可以在关闭表单之前简单地删除 form_closure 事件的事件处理程序:
In response to pix0rs concern - yes you are correct that you will not be able to programatically close the app. However, you can simply remove the event handler for the form_closing event before closing the form:
this.FormClosing -= new System.Windows.Forms.FormClosingEventHandler(this.Form1_FormClosing);
this.Close();
