Question

我在PowerShell中编写了一个非常广泛的300多行用户添加脚本，专为非管理员设计，无需管理员权限（自行提升）即可将用户添加到Windows域，而无需进入ADUC。

有一个部分（下面）要求提供电话号码，清理输入并正确格式化以便同步到Azure / O365。它还检查以确保输入为办公室和手机的10位数，如果他们没有抛出错误对话框。我想找到一种方法，不仅可以抛出错误框，还可以让脚本返回电话输入代码的顶部，让他们在按下OK按钮后重新输入数字。这就是我不知所措 - 让它回到该部分的顶部。

如上面的评论所述，如果您将代码包装在do /中，直到您可以循环允许用户重试输入数据。请参阅下面的更新脚本。（另外，由于其他一切都是Winforms，我修改了脚本以使用Winforms MessageBox类而不是调用wscript.shell。）

您还可以将电话号码解析转换为函数，并在数据未验证您的方式时以递归方式调用。然后只需调用该函数并从返回的对象中提取worknumber和cellnumber属性。如果他们点击取消，则返回$false（然后$return.worknumber将不会给出任何结果）因此可以验证它是否为假或仅以空白数据结束（取决于您需要的是什么）那个脚本要做。
