如何跟踪c#中的Powershell进程和错误?

I am currently writing a WPF application which allows a user to convert a

我目前正在编写一个WPF应用程序，允许用户转换a

.vmdk (VMware vm file)

.vmdk(VMware虚拟机文件)

to a

到一个

.vhdx (Hyper-V vm file).

.vhdx(hyper - v vm文件)。

I am using a cmdlet (ConvertTo-MvmcVirtualHardDisk) which resides in the MvmcCmdlet.psd1 module, which comes with

我正在使用一个cmdlet (ConvertTo-MvmcVirtualHardDisk)，它驻留在MvmcCmdlet中。psd1模块

Microsoft Virtual Machine Converter 3.0.0

微软虚拟机转换器3.0.0

I am testing the functionality with hardcoded paths atm.

我正在使用硬编码路径atm对功能进行测试。

Here's my current code:

这是我目前的代码:

using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Management.Automation;
using System.Management.Automation.Runspaces;
using System.Threading;
using System.Windows;

namespace PowershellTestArea
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
    private string output { get; set; }

    public MainWindow()
    {
        InitializeComponent();
    }

    private void Button_OnClick(object sender, RoutedEventArgs e)
    {
        new Thread(() =>
        {
            Runspace rs = RunspaceFactory.CreateRunspace();
            rs.ThreadOptions = PSThreadOptions.UseCurrentThread;
            rs.Open();

            PowerShell ps = PowerShell.Create();

            ps.Runspace = rs;

            ps.AddCommand("Import-Module", true).AddParameter("Name", @"C:\Program Files\Microsoft Virtual Machine Converter\MvmcCmdlet.psd1");
            ps.Invoke();

            Debug.WriteLine(ps.HadErrors);

            Thread.Sleep(3000);

            ps.AddCommand("ConvertTo-MvmcVirtualHardDisk")
            .AddParameter("–SourceLiteralPath", @"'C:\VM\Windows 7 x64.vmdk'")
            .AddParameter("-VhdFormat", "Vhdx");
            Debug.WriteLine(ps.HadErrors);
            ps.BeginInvoke();

            IAsyncResult asyncResult = ps.BeginInvoke<PSObject, PSObject>(null, output);

            while (!asyncResult.IsCompleted)
            {
                Debug.WriteLine("Running...");
            }

            Debug.WriteLine(ps.Streams.Error.ToString());

            rs.Close();

        }).Start();
    }
}
}

The reason that i'm doing the Powershell code in a new Thread is, that the module is imported and can be used at runtime. I want to make sure that it is imported in the same session, so to speak. The process:

我在新线程中执行Powershell代码的原因是，模块是导入的，可以在运行时使用。我想确保它是在同一个会话中导入的。过程:

ps.AddCommand("ConvertTo-MvmcVirtualHardDisk")
            .AddParameter("–SourceLiteralPath", @"'C:\VM\Windows 7 x64.vmdk'")
            .AddParameter("-VhdFormat", "Vhdx");
            Debug.WriteLine(ps.HadErrors);
            ps.BeginInvoke();

finishes really fast (HadErrors returns false), and when run in powershell, it takes about 40 minutes to complete.

结束非常快(HadErrors返回false)，在powershell中运行时，大约需要40分钟完成。

Can anyone tell me what to do, to track the progress, so the conversion can be done/finish?

谁能告诉我怎么做，跟踪进度，这样转换可以完成吗?

EDIT:

编辑:

Difference from this question is that my process does not finish correctly, and I'm wondering how to give the process time to finish.

与这个问题不同的是，我的流程没有正确完成，我想知道如何给流程时间来完成。

Progress in Powershell is a stream, just like Error, Warning, Debug etc. All streams are available through the PSDataStreams class, exposed through the Powershell.Streams property.

Powershell中的进展是一个流，就像错误、警告、调试等。所有流都可以通过PSDataStreams类获得，通过Powershell公开。流属性。

You can listen for Progress events on the Progress stream by subscribing to the DataAdded event, eg:

您可以订阅dataadd事件来侦听进度流上的进度事件，例如:

ps.Streams.Progress.DataAdded += (sender,args) => {
    var records = (PSDataCollection<ProgressRecord>)sender;
    var current=records[args.Index];
    Console.WriteLine("VM conversion is {0} percent complete", current.PercentComplete);
};

You can listen to the rest of the streams in a similar way, eg the Errors stream is a collection of ErrorRecord objects. You can listen to information, Verbose, Warning messages in the same way, to construct a full log of what happened.

您可以以类似的方式侦听其他流，如错误流是错误记录对象的集合。您可以以同样的方式侦听信息、详细信息和警告消息，从而构建完整的事件日志。

Another option is to create a Transcript of a Powershell session. This saves all the commands and output of a session to a text file, from the moment you call Start-Transcript until you call Stop-Transcript, eg:

另一个选项是创建Powershell会话的副本。这将把会话的所有命令和输出保存到文本文件中，从调用Start-Transcript到调用Stop-Transcript，例如:

Start-Transcript -OutputDirectory 'c:\mylogs' -noclobber -IncludeInvocationHeader

ConvertTo-MvmcVirtualHardDisk ...

Stop-Transcript

or the equivalent code using C#.

或者使用c#的等效代码。

This is a quick&dirty way to capture everything for troubleshooting

这是一种快速而又肮脏的方法，可以捕获故障诊断所需的所有信息
