我正在从这样的 C# 工具运行 PowerShell 脚本:
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);
}
在我需要来自其他程序集的特殊 Cmdlet 之前,脚本中的几乎所有内容都可以正常工作。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:\dev\tool\Microsoft.SharePoint.dll' because it does not exist."
跑步时
$snapin = Get-PSSnapin | Where-Object {$_.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,所以我猜它与未从 C# 工具转发的 PATH 或 Scope 有关。使用 AddCommand 的参数 useLocalScope 或其他参数没有产生任何结果(尽管我不确定这是否与路径有关)。
如何使脚本工作并找到外部程序集?
