来自 C# 的多行 Powershell 块

Question

使用此代码从 C# 运行我的 Powershell 代码，一切正常

        using(PowerShell powershellCommand = PowerShell.Create())
        {
            powershellCommand.AddScript(File.ReadAllText(@"C:\Path_to_script")).Invoke();
            System.Collections.ObjectModel.Collection<System.Management.Automation.PSObject> results = powershellCommand.Invoke();
            foreach (PSObject result in results)
            {
                logg.AppendText(result + ""); 
            }
        }

脚本文件中的代码。

$env:tmp = "env_location"
Import-PSSession $(New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri 
server_url) | Out-Null
$device = Get-Mailbox -Identity IDENTITY | Get-MailboxStatistics | Select-Object TotalItemSize

return $device

IDENTITY 是这里的问题，因为我希望它是动态的，因此不能硬编码到脚本文件中。 我已经尝试过Execute multiple line PowerShell Script from C# 中的解决方案，如下所示：

        using(PowerShell powershellCommand = PowerShell.Create())
        {
            string script = @"
            $env:tmp = 'env_location'
            Import-PSSession $(New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri server_url) | Out-Null
            $device = Get-Mailbox -Identity DYNAMIC_IDENTITY | Get-MailboxStatistics | Select-Object TotalItemSize

            return $device
            ";

            powershellCommand.AddScript(script)).Invoke();
            System.Collections.ObjectModel.Collection<System.Management.Automation.PSObject> results = powershellCommand.Invoke();
            foreach (PSObject result in results)
            {
                logg.AppendText(result + ""); 
            }
        }

感觉这应该可行，但根本没有输出。也没有崩溃，有什么想法吗？

谢谢

按照我上面的cmets，试试这个。

using System;
using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.Management.Automation;
using System.Management.Automation.Runspaces;

namespace PowerShellSample
{
    public class Exchange
    {
        public static Collection<PSObject> GetTotalMailboxSize(string identity)
        {
            using(PowerShell powershellCommand = PowerShell.Create())
            {
                powershellCommand.AddScript(File.ReadAllText(@"C:\\Path_to_script")).AddParameter("Identity", identity);
                IAsyncResult poshTask = powershellCommand.BeginInvoke();
                Collection<PSObject> returnCollection = new Collection<PSObject>();
                foreach (PSObject psObj in powershellCommand.EndInvoke(poshTask))
                {
                    returnCollection.Add(psObj);
                }
                return returnCollection;
            }
        }
    }
}

PowerShell 脚本：

[CmdletBinding()]
Param (
    [Parameter(Mandatory = $true)]
    [System.String]
    $Identity
)

$env:tmp = "env_location"
Import-PSSession $(New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri server_url) | Out-Null
$Device = Get-Mailbox -Identity $Identity | Get-MailboxStatistics | Select-Object TotalItemSize

return $device

如果您想提供更多参数，您可以在方法中使用Dictionary<string, Object>。这样您就可以传递您的 ConnectionUri 或您可能需要的任何其他参数。

public static Collection<PSObject> GetTotalMailboxSize(string identity, Dictionary<string, Object> parameters)
{
    using(PowerShell powershellCommand = PowerShell.Create())
    {
        powershellCommand.AddScript(File.ReadAllText(@"C:\\Path_to_script"));
        foreach (var key in parameters.Keys)
        {
            powershellCommand.AddParameter(key, parameters[key]);
        }
        IAsyncResult poshTask = powershellCommand.BeginInvoke();
        Collection<PSObject> returnCollection = new Collection<PSObject>();
        foreach (PSObject psObj in powershellCommand.EndInvoke(poshTask))
        {
            returnCollection.Add(psObj);
        }
        return returnCollection;
    }
}
