我如何检查是否在消息框中单击了是 [英] how do i check if yes has been clicked on a message box

问题描述

有人可以教我如何确定是否在消息框中单击了是"或否"吗?我的代码如下所示:

Can anyone teach me how i can determine if ''yes'' or ''no'' has been clicked on a message box? my code is as shown below:

MessageBox.Show("Applicant already has interview date. Do you want to overwrite this date?", "Set interview", MessageBoxButtons.YesNo, MessageBoxIcon.Question);
    if (DialogResult.Yes)
    {
        sql = "insert into interview(FileLoc, date, time) values('" + id + "', '" + intdate.Text.ToString() + "', '" + inttime.Text.ToString() + "')";
        cmd.ExecuteNonQuery();
    }

推荐答案

捕获Show方法的返回值并针对DialogResult枚举进行测试

Capture the return value from the Show method and test against the DialogResult enum

DialogResult result = MessageBox.Show("Applicant already has interview date. Do you want to overwrite this date?", "Set interview", MessageBoxButtons.YesNo, MessageBoxIcon.Question);

if(result == DialogResult.Yes)
{
}
