我正在从C#工具运行PowerShell脚本,如下所示:
using (PowerShell pshell = PowerShell.Create())
{
pshell.AddCommand(scriptFullPath);
pshell.AddParameter("username", user);
pshell.AddParameter("password", pass);
PSDataCollection<PSObject> outputCollection = new PSDataCollection<PSObject>();
PSInvocationSettings settings = new PSInvocationSettings();
settings.ErrorActionPreference = ActionPreference.Stop;
pshell.Invoke(null, outputCollection, settings);
}
几乎所有内容在脚本中都能正常工作,直到我需要来自其他程序集的特殊 Cmdlet。add-PSSnapin 命令将始终失败,并显示:
Exception: The Windows PowerShell snap-in 'Microsoft.SharePoint.Powershell' is not installed on this computer.
Exception: Cannot bind parameter 'Path' to the target. Exception setting "Path": "Cannot find path 'D:devtoolMicrosoft.SharePoint.dll' because it does not exist."
运行时
$snapin = Get-PSSnapin | Where-Object {$_.Name -eq "Microsoft.SharePoint.Powershell"}
if ($snapin -eq $null)
{
Write-Host "Loading SharePoint Powershell Snapin"
Add-PSSnapin "Microsoft.SharePoint.Powershell"
Add-Type -Path "Microsoft.SharePoint.dll"
Add-Type -Path "Microsoft.SharePoint.Runtime.dll"
}
直接在PowerShell窗口中运行脚本时,一切正常,所以我想它与未从C#工具转发的PATH或范围有关。使用AddCommand或其他参数的参数useLocalScope没有产生任何结果(尽管我不确定这是否与路径有关(。
如何使脚本工作并查找外部程序集?
SharePoint PowerShell 管理单元仅在 64 位中可用。您的 C# 工具可能作为 x86 进程运行,因此会给您错误"未安装"。此外,您可能必须"以管理员身份"运行该程序,因为某些命令需要它才能工作。
第二个错误是,您是对的,默认情况下没有为 SharePoint 设置的 PATH 变量。解决方法是指定.dll的完整路径(并更改安装的版本号(,例如
Add-Type -Path "C:Program FilesCommon Filesmicrosoft sharedWeb Server Extensions15ISAPIMicrosoft.SharePoint.dll"
