我正在尝试在powershell中以编程方式注册soap扩展，就像它描述here一样，但我对这个特定方法有问题：
[System.Type]::GetType("System.Configuration.ConfigurationElementCollection, System.Configuration", $true)
Exception calling "GetType" with "2" argument(s): "Could not load file or assembly 'System.Configuration' or one of its dependencies. The system cannot find the file specified."
直接在powershell.exe中运行此行时，这是Fusion Log Viewer的输出：
*** Assembly Binder Log Entry (9/20/2013 @ 10:42:57 AM) ***
The operation failed.
Bind result: hr = 0x80070002. The system cannot find the file specified.

运行此PowerGUI脚本编辑器时，这是Fusion Log Viewer的输出：

当然，GAC中有汇编：
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
如果我在上面的PowerShell行中使用程序集全名，则会出现同样的问题。
答案 0 :(得分：2)
除非类型在当前程序集或mscorlib.dll中，否则您需要指定程序集限定的类型名称。这应该有效：
[System.Type]::GetType("System.Configuration.ConfigurationElementCollection, System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a", $true)
