问题描述

我有一个模式对话框，需要隐藏关闭（X）按钮，但是我不能使用
ControlBox = false ，因为我需要保持

I have a modal dialog, and need to hide the Close (X) button, but I cannot use ControlBox = false, because I need to keep the Minimize and Maximize buttons.

I need to hide just Close button, is there any way to do that?

推荐答案

您无法将其隐藏，但是可以通过覆盖表单的CreateParams属性来禁用它。

You can't hide it, but you can disable it by overriding the CreateParams property of the form.

private const int CP_NOCLOSE_BUTTON = 0x200;
protected override CreateParams CreateParams
{
    get
    {
       CreateParams myCp = base.CreateParams;
       myCp.ClassStyle = myCp.ClassStyle | CP_NOCLOSE_BUTTON ;
       return myCp;
    }
}
