如何将XAML中的DatePicker和TextBox信息转换为Powershell变量？

标签： wpf xaml powershell datepicker textbox

我不熟悉脚本（第一年），这是我第一次尝试从VisualStudio中获取WPF应用程序并将其XAML代码转换为可以与Powershell一起使用的代码。我尝试创建一个小应用程序，允许我将Active Directory用户名输入到TextBox字段中，然后从DatePicker对象中选择一个日期，然后将这两个信息转换为Powershell变量。从那里，我为AD用户启用VPN访问，然后将日期用作＆＃34;截止日期＆＃34;此时我将禁用用户的访问权限。这两个变量也将输出到我们服务器上的.csv文件中，该文件将由计划任务每​​天读取。如果截止日期与当天匹配，则将触发另一个禁用用户VPN访问的脚本。 （这个计划的PowerShell脚本不包含在这里，稍后会写。）

请查看我的代码并帮助我弄清楚为什么我无法从TextBox和DatePicker中检索信息以填充我的Powershell变量！我的问题似乎出现在＆＃34;实际上让对象工作＆＃34;部分。我得到一个错误＆＃34; WPFtextbox_Username.Text＆＃34;和＆＃34; DatePicker.SelectedDate.Value.Date.ToShortDateString＆＃34;在Powershell中无效，因此当我写入.csv文件时，变量$ ADUser和$ ExpirationDate为空。这个脚本noob将会感激任何帮助！

发现其他一些看起来没有写入代码的东西，例如方法调用中缺少括号（），变量中缺少美元符号（$）以及日期选择器的错误名称（应该是WPFDatepicker）。我在下面运行了更新的代码，它在文本文件中产生了预期的结果。
