如何使用Add-Type加载Microsoft.Web.Deployment？

Question

我正在编写一些使用MSDeploy API的PowerShell脚本.我可以使用加载程序集

[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.Web.Deployment")

该地点位于GAC:

PS > [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.Web.Deployment") | fl Location

Location : C:\Windows\assembly\GAC_MSIL\Microsoft.Web.Deployment\7.1.0.0__31bf3856ad364e35\Microsoft.Web.Deployment.dll

但是,我无法使用Add-Type加载程序集.我收到一个错误,说无法找到程序集,并且缺少一个或多个程序集.

PS > Add-Type -AssemblyName Microsoft.Web.Deployment
Add-Type : Cannot add type. The assembly 'Microsoft.Web.Deployment' could not be found.
At line:1 char:9
+ Add-Type <<<<  -AssemblyName Microsoft.Web.Deployment
    + CategoryInfo          : ObjectNotFound: (Microsoft.Web.Deployment:String) [Add-Type], Exception
    + FullyQualifiedErrorId : ASSEMBLY_NOT_FOUND,Microsoft.PowerShell.Commands.AddTypeCommand

Add-Type : Cannot add type. One or more required assemblies are missing.
At line:1 char:9
+ Add-Type <<<<  -AssemblyName Microsoft.Web.Deployment
    + CategoryInfo          : InvalidData: (:) [Add-Type], InvalidOperationException

Answer 1

PowerShell仅允许通过其部分/简单名称加载某个预定义的程序集.您将需要通过其完全限定名称加载它,例如:

Add-Type -AssemblyName ('Microsoft.Web.Deployment, Version=7.1.0.0, ' +
                        'Culture=neutral, PublicKeyToken=31bf3856ad364e35')
