不能从程序集System.Configuration中的[System.Type] :: GetType类型

Question

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.

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。

Answer 1

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)
