Question

我有一个简单的程序，检查两个数字是否加在一起= =到文本框答案（mathAnswer），但是当我输入正确答案并单击提交按钮时，我一直从answerstatus标签中得到“不正确”？有谁知道为什么？

您的比较必须在用户点击提交按钮后进行。因此，比较代码应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!";
        }
    }

数学逻辑不起作用
