确认消息

Question

如果用户检查Checkbox,我如何编码显示MessageBox.Show("...",使用YesNoCancel消息框中的按钮,当用户单击否时,另一个MessageBox.Show弹出？

到目前为止我的代码是这样的,它不起作用:

private void lipsCheckBox_CheckedChanged(object sender, EventArgs e)
    {
        if (lipsCheckBox.Checked = MessageBox.Show("...?",
            "Want something else?",
            MessageBoxButtons.YesNoCancel, MessageBox.Show("...?",
            "Yea, Burt's bees?",
            MessageBoxButtons.YesNoCancel, MessageBox.Show("...??",
            "Hell yea LipxMedx?",
            MessageBoxButtons.YesNoCancel),
            MessageBoxIcon.Question);
    }

Answer 1

你必须知道 MessageBox Dialog

if (checkBox1.Checked && (MessageBox.Show("Yes or no", "The Title", 
    MessageBoxButtons.YesNo, MessageBoxIcon.Question, 
    MessageBoxDefaultButton.Button1) == System.Windows.Forms.DialogResult.Yes))
{
    //TODO: Stuff
}

Answer 2

做这样的事情:

if (checkBox1.Checked)
{

     DialogResult dr = MessageBox.Show("Message.", "Title", MessageBoxButtons.YesNoCancel, 
        MessageBoxIcon.Information);

    if (dr == DialogResult.Yes)
    {
        // Do something
    }
}

您应该可以使用此代码段来完成您需要的其余部分.

你可以这样做:

private void lipsCheckBox_CheckedChanged(object sender, EventArgs e)
{
    if (lipsCheckBox.Checked)
    {     
        DialogResult dr = MessageBox.Show("...?", "Want something else?", MessageBoxButtons.YesNoCancel, MessageBoxIcon.Information);

        if(dr == DialogResult.Yes)
        {
            //
        }
        else if(dr == DialogResult.Cancel)
        {
            //
        }
    }
}
