Powershell 无法[System.Type]：：从程序集System.Configuration获取类型的GetType,powershell,reflection,Powershell,Reflection,我正试图在powershell中以编程方式注册soap扩展，正如前面所述，但我对这一特定方法有问题： [System.Type]：：GetType（“System.Configuration.ConfigurationElementCollection，System.Configuration”，$true）使用“2”参数调用“GetType”时出现异常：“无法加载文件或程序集'System.Configuration'或其依赖项之一。系统找不到指定的文件。” 这是直接在powershell.

我正试图在powershell中以编程方式注册soap扩展，正如前面所述，但我对这一特定方法有问题：

[System.Type]：：GetType（“System.Configuration.ConfigurationElementCollection，System.Configuration”，$true）

使用“2”参数调用“GetType”时出现异常：“无法加载文件或程序集'System.Configuration'或其依赖项之一。系统找不到指定的文件。”

这是直接在powershell.exe中运行此行时Fusion Log Viewer的输出：

当然，GAC中有装配：

The Global Assembly Cache contains the following assemblies:
  System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a, processorArchitecture=MSIL
  System.Configuration, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a, processorArchitecture=MSIL

如果在上面的powershell行中使用程序集全名，则会出现相同的问题。

您需要指定程序集限定类型名称，除非该类型位于当前程序集或mscorlib.dll中。这应该起作用：

[System.Type]::GetType("System.Configuration.ConfigurationElementCollection, System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a", $true)

您在哪里看到System.GetType接受两个参数？$true在您的调用中的含义是什么？@DavidBrabant:see，true在找不到类型时引发异常是的，它现在正在工作，但是如果我选择版本4.0.0.0，它会再次引发异常，系统无法找到指定的文件。你知道为什么会发生这种情况吗？@Megan powershell v2.0在2.0 clr上运行。它无法加载4.0版本，因为它使用不同的运行时。它甚至找不到程序集，因为这两个版本有单独的GAC。
