Question

C#中怎么判断消息框有没有按确定键呢？

我想在按确定键的时候导出别的界面

Answer 1

判断返回值。例子如下：
string message = "You did not enter a server name. Cancel this operation?";
string caption = "No Server Name Specified";
MessageBoxButtons buttons = MessageBoxButtons.YesNo;
DialogResult result;

// Displays the MessageBox.

result = MessageBox.Show(this, message, caption, buttons,
MessageBoxIcon.Question, MessageBoxDefaultButton.Button1);

if(result == DialogResult.Yes)
{

// Closes the parent form.

this.Close();

}

Answer 2

if(MessageBox.Show(this, message, caption,buttons,MessageBoxIcon.Question,MessageBoxDefaultButton.Button1)==DialogResult.OK)
{
按了确定键
}
