我对C＃很陌生。但是有C，Python等经验。 这是我的问题。
我有一个有两种形式的GUI。 第一种形式要求提供单元的序列号，第二种形式是主要测试的位置。
在第二种形式中，有一个阶段，我等待控制器（DUT）启动，以便我可以获取启动信息。 我得到了大部分代码，但问题就在这里。
我禁用“下一步”按钮，直到用户为设备供电。但是，即使禁用了按钮，也会发生点击事件（当用户点击禁用按钮时），并根据他点击的次数，SW会验证点击次数并跳过下一个阶段。
我该如何解决这个问题？或者，还有另一种更好的方法来编写代码吗？

我没有完全明白禁用按钮的含义。 如果你做了以下它应该工作：
NextBtn.IsEnabled = false;
NextBtn.Visibility = Visibility.Collapsed;
否则，你可以通过创建一个bool来禁用该方法：
bool hasOccured;
Private void Reason_Occured(EventArgs)
{
hasOccured = true;
}
private void NextBtn_Click(Args)
{
if(hasOccured) return;
//code chunk
}

很抱歉迟到的回复。
我成功解决了这个问题。好像我必须使用Switch，Case语句而不是If语句。
为你的所有帮助干杯
