【问题描述】：
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
+ $Form.ShowDialog() | out-null
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [], MethodInvocationException
+ FullyQualifiedErrorId : RuntimeException
现在相当奇怪的是，"USB_Disable=" 字符串只能在从未与$Form.ShowDialog() 接触的 hereString 中找到。下面是包含 hereString 的初始化函数的摘录，然后是表单加载器函数。如果您需要完整的代码，请告诉我（大约 800 行）

这是我以前从未遇到过的一个非常奇怪的错误，不知何故 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）。
任何帮助将不胜感激！
【问题讨论】：
-
无论如何你可以把它归结为一个最小的可验证的例子？更短的东西来产生你的问题？我不想要完整的代码（反正这里没有空间），但我们无法运行你在那里拥有的东西，因为我看到至少一个我们没有的功能
-
还可以查看jonathanmedd.net/2012/05/… 以摆脱所有这些 if 语句。
$USBBlock = [System.Convert]::ToBoolean($ini.USB.USB_Block) -
感谢您的转换想法，我认为这更多地与脚本如何加载到内存中有关，并且更多的是 WMI 的问题。另外，这里有一个人有类似错误的线程，那里的人建议运行一个 ccleaner：link
-
转换不是为了解决问题，而是帮助使代码更简洁。如果是这样，那将是一个奇怪的错误。
-
我认为它现在与系统相关（Windows 10 技术预览版）。所以代码与它无关，我发布的那个链接几乎总结了任何人都可以给出的唯一答案。我现在正在盲目开发......感觉就像旧的大型机蜗牛邮件打卡时代。我将尝试将文件移动到其他驱动器，可能尝试更改编码并重新安装 WMI。
