我有一个简单的程序，检查两个数字加在一起是否==文本框答案(mathAnswer)，但是当我输入正确的答案并单击提交按钮时，我一直从answerstatus标签获得"不正确" ?有人知道为什么吗?

必须在用户单击提交按钮之后进行比较。因此，比较代码应该放在该按钮的按钮单击事件处理程序中，如下所示:

private void submitAnswer_Click(object sender, RoutedEventArgs e)
    {
      if (answer.ToString() == mathAnswer.Text) 
        {
            answerStatusLabel.Text = "Correct!";
        }
      else 
        {
            answerStatusLabel.Text = "Incorrect!";
        }
    }
