所以我正在开发一个基于Powershell的WPF应用程序，我收到以下错误：
Exception calling "ShowDialog" with "0" argument(s): "Unidentified: USB_Disable="
At C:\Users\miste\OneDrive\Documents\Visual Studio 2015\Projects\Vaccinate-USB\Vaccinate-USB\Vaccinate-USB.ps1:344 char:5
+ $Form.ShowDialog() | out-null
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [], MethodInvocationException
+ FullyQualifiedErrorId : RuntimeException
现在相当奇怪的是，"USB_Disable="字符串只能在一个永远不会与$Form.ShowDialog()联系的hereString中找到。下面是初始化函数的摘录，其中包含hereString，然后是表单加载器函数。如果您需要完整的代码，请告诉我（它大约有800行）
初始化程序：

这是一个非常奇怪的错误，我以前从未遇到过，不知怎的，ShowDialog方法正在获取一个永远不应该被解析的字符串（更不用说甚至不允许访问）。< / p>
非常感谢任何帮助！

问题在于.NET内存管理错误，运行CCleaner并重启系统。
