c# - 使用 System.Management.Automation 调用 powershell 时如何从远程命令传递警告和详细流？

Question

我正在尝试使用 C# 中的 PowerShell 远程调用命令(在本地虚拟机上或使用网络)。我正在使用 https://www.nuget.org/packages/Microsoft.PowerShell.5.ReferenceAssemblies/ 中的 System.Management.Automation 库

由于我不知道的原因，警告和详细消息没有被记录下来。

在 C# 中本地调用 commnd 时，它工作正常。

我尝试了各种与流相关的设置($verbosepreference、$warningpreference)，但我认为它们并不相关 - 从控制台调用 PowerShell 时不存在此问题。

我检查了与虚拟机的远程连接(Invoke-Command 的 -VmName 参数)和网络中的计算机(Invoke-Command 的 -ComputerName 参数)- 都遇到了这个问题。

我尝试在 PowerShell Invoke() 中找到一些神奇的开关，使这些流被传递 - 我发现了一个名为 RemoteStreamOptions ( https://learn.microsoft.com/en-us/dotnet/api/system.management.automation.remotestreamoptions?view=powershellsdk-1.1.0 ) 的东西，但设置它没有帮助。

我能做些什么来让它发挥作用吗？

namespace ConsoleApp2
{
using System;
using System.Linq;
using System.Management.Automation;
using System.Management.Automation.Runspaces;
using System.Security;

class Program
{
    static void Main(string[] args)
    {
        var script = @"
        $VerbosePreference='Continue' #nope, it's not about these settings
        $WarningPreference = 'Continue'
        Write-Host "" ------- $env:computername  ------- ""
        Write-Warning ""Write warning directly in warn script""
        Write-Error ""Write error directly in warn script""
        Write-Verbose ""Write verbose directly in warn script"" -verbose
        Write-Host ""Write host directly in warn script""   
        Write-Information ""Write Information in warn script""
        ";


        Call(script, command =>
            {
                SecureString password = new SecureString();
                "admin".ToCharArray().ToList().ForEach(c => password.AppendChar(c));
                command.Parameters.Add("Credential", new PSCredential("admin", password));
                command.Parameters.Add("VmName", new[] { "190104075839" });
            }
    );
        Call(script);
    }

    private static void Call(string script, Action<Command> addtionalCommandSetup = null)
    {
        using (var shell = PowerShell.Create())
        {
            shell.Streams.Information.DataAdded += LogProgress<InformationRecord>;
            shell.Streams.Warning.DataAdded += LogProgress<WarningRecord>;
            shell.Streams.Error.DataAdded += LogProgress<ErrorRecord>;
            shell.Streams.Verbose.DataAdded += LogProgress<VerboseRecord>;
            shell.Streams.Debug.DataAdded += LogProgress<DebugRecord>;



            var command = new Command("Invoke-Command");
            command.Parameters.Add("ScriptBlock", ScriptBlock.Create(script));
            addtionalCommandSetup?.Invoke(command);
            shell.Commands.AddCommand(command);
            shell.Invoke();
            Console.ReadKey();
        }
    }

    private static void LogProgress<T>(object sender, DataAddedEventArgs e)
    {
        var data = (sender as PSDataCollection<T>)[e.Index];
        Console.WriteLine($"[{typeof(T).Name}] {Convert.ToString(data)}");
    }
}
}

我认为问题可能是您正在使用 var shell = PowerShell.Create() 创建本地 PowerShell session , 然后用 Invoke-Command 创建一个单独的远程 session 并且流没有正确通过。如果你直接创建一个远程 session ，它工作正常。这是使用远程运行空间的代码的简化版本:

namespace ConsoleApp2
{
    using System;
    using System.Linq;
    using System.Management.Automation;
    using System.Management.Automation.Runspaces;
    using System.Security;

    class Program
    {
        static void Main(string[] args)
        {
            var script = @"
            Write-Host ""-------$env:computername-------""
            Write-Warning ""Write warning directly in warn script""
            Write-Error ""Write error directly in warn script""
            Write-Verbose ""Write verbose directly in warn script"" -verbose
            Write-Host ""Write host directly in warn script""
            Write-Information ""Write Information in warn script""
            ";

            SecureString password = new SecureString();
            "Password".ToCharArray().ToList().ForEach(c => password.AppendChar(c));
            PSCredential credentials = new PSCredential("UserName", password);

            WSManConnectionInfo connectionInfo = new WSManConnectionInfo();
            connectionInfo.ComputerName = "TargetServer";
            connectionInfo.Credential = credentials;

            using (var shell = PowerShell.Create())
            {
                using (var runspace = RunspaceFactory.CreateRunspace(connectionInfo))
                {
                    runspace.Open();

                    shell.Runspace = runspace;

                    shell.Streams.Information.DataAdded += LogProgress<InformationRecord>;
                    shell.Streams.Warning.DataAdded += LogProgress<WarningRecord>;
                    shell.Streams.Error.DataAdded += LogProgress<ErrorRecord>;
                    shell.Streams.Verbose.DataAdded += LogProgress<VerboseRecord>;
                    shell.Streams.Debug.DataAdded += LogProgress<DebugRecord>;

                    shell.AddScript(script);
                    shell.Invoke();
                }
            }

            Console.ReadKey();
        }

        private static void LogProgress<T>(object sender, DataAddedEventArgs e)
        {
            var data = (sender as PSDataCollection<T>)[e.Index];
            Console.WriteLine($"[{typeof(T).Name}] {Convert.ToString(data)}");
        }
    }
}
