通过 PowerShell 加载类型库并编写 Windows Live Writer 脚本

一般来说，我对 COM 和 Windows 编程/脚本非常陌生。我想做的是编写 Windows Live Writer 脚本；根据文档，我可以打电话

  $o = New-Object -c WindowsLiveWriter.Application

我需要先加载 TLB，所以我应该调用add-type命令，不幸的是它失败了：

PS C:\Users\NoWhereMan> add-type windowslivewriter.application
Add-Type : c:\Users\NoWhereMan\AppData\Local\Temp\a7ifbimo.0.cs(1) : A namespace does not directly contain members such
 as fields or methods
c:\Users\NoWhereMan\AppData\Local\Temp\a7ifbimo.0.cs(1) : >>> windowslivewriter.application
At line:1 char:9
+ add-type <<<<  windowslivewriter.application
    + CategoryInfo          : InvalidData: (c:\Users\NoWher...elds or methods:CompilerError) [Add-Type], Exception
    + FullyQualifiedErrorId : SOURCE_CODE_ERROR,Microsoft.PowerShell.Commands.AddTypeCommand

Add-Type : Cannot add type. There were compilation errors.
At line:1 char:9
+ add-type <<<<  windowslivewriter.application
    + CategoryInfo          : InvalidData: (:) [Add-Type], InvalidOperationException
    + FullyQualifiedErrorId : COMPILER_ERRORS,Microsoft.PowerShell.Commands.AddTypeCommand

物有所值，我运行的是 Windows7 x64

EDIT：x64 是关键问题，我需要将 PSH 作为 x86 进程运行

Thanks

From help add-type:

将 Microsoft .NET Framework 类型（类）添加到 Windows PowerShell 会话。

but windowslivewriter.application不是 .NET 类型。

PowerShell (PSH) directly supports COM objects, you do not need to take any special steps to load the Type Library (TLB)¹, just call the methods diretcly as given in the documentation http://msdn.microsoft.com/en-us/library/aa738851.aspx for the component. E.g.:

$lw = New-Object -com WindowsLiveWriter.Application   
$lw.NetPost()

启动新的帖子编辑器。

摘要：你愿意not需要先加载TLB。

在 64 位 Windows 下，您可能需要确保正在运行 PSH 的 32 位实例（“x86”）才能执行此操作（取决于 Live Writer 组件是在进程内还是在进程外运行）。

¹ Strictly speaking, this only applies to COM types that support scripting with IDispatch, but in practice there are few that don't.
