使用PowerShell脚本安装COM +组件中的问题 [英] Issues in installing COM + Component using PowerShell script

问题描述

我正在尝试使用Powershell安装COM +组件.但是我遇到了以下错误.

I'm trying to install COM + Component using powershell. But I'm getting following error.

Unable to find type [some.dll]. Make sure that the assembly that contains this 
type is loaded.

+     $comAdmin.InstallComponent("test", [some.dll]);
+     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (COMITSServer.dll:TypeName) [], Runtime 
   Exception
    + FullyQualifiedErrorId : TypeNotFound

这是我的powershell脚本:

and here is my powershell script:

  $comAdmin = New-Object -comobject COMAdmin.COMAdminCatalog;
    $comAdmin.InstallComponent("some", [some.dll]);
    #if an exception occurs in installing COM+  then display the message below
    if (!$?)
    {
        Write-Host "Unable to Install the COM+ Component. Aborting..."
        exit -1
    }

我的powershell版本是4.0有人可以帮我吗?

My powershell version is 4.0 Can someone please help me on this.

谢谢.

推荐答案

PowerShell中的方括号表示类型，例如 [string] 或 [int32] 或 [System.Array] 或 [System.Math] .该错误消息是抱怨的，因为您告诉PowerShell COMITSServer.dll是已注册并已加载的数据类型.

Square brackets in PowerShell indicate a type, like [string] or [int32] or [System.Array] or [System.Math]. The error message is complaining because you're telling PowerShell that COMITSServer.dll is a registered and loaded data type.

另外，对我来说， COMAdminCatalog 的 InstallComponent 方法似乎具有四个参数，而不是两个.您应该可以通过查看定义来确认这一点，但是我不知道v2.0是否支持这样做:

Additionally, the InstallComponent method of COMAdminCatalog appears to me to have four arguments, not two. You should be able to confirm that by looking at the definition, but I don't know if v2.0 supports doing it like this:

PS U:\> $comAdmin = New-Object -comobject COMAdmin.COMAdminCatalog
PS U:\> $comAdmin | gm | where { $_.Name -eq 'InstallComponent' }


   TypeName: System.__ComObject#{790c6e0b-9194-4cc9-9426-a48a63185696}

Name             MemberType Definition
----             ---------- ----------
InstallComponent Method     void InstallComponent (string, string, string, string)

这样，我会尝试这样做:

As such, I would try this:

$comAdmin.InstallComponent("ITSServerOO2", "COMITSServer.dll", "", "");

这似乎就是VB代码

That appears to be how the VB code here calls the same method:

'  Open a session with the catalog.
'  Instantiate a COMAdminCatalog object. 
Dim objCatalog As COMAdminCatalog
Set objCatalog = CreateObject("COMAdmin.COMAdminCatalog")

[...]

'  Install components into the application.
'  Use the InstallComponent method on COMAdminCatalog. 
'  In this case, the last two parameters are passed as empty strings.
objCatalog.InstallComponent "MyHomeZoo","MyZoo.DLL","","" 

此处我相信，这是该函数的类定义，尽管我对COM +不够了解，无法知道COMAdminCatalog和ICOMAdminCatalog是否相同.

Here is the class definition of that function, I believe, athough I'm not familiar enough with COM+ to know if COMAdminCatalog and ICOMAdminCatalog are the same.
