Question

我通过在C＃中使用System.Management.Automation命名空间运行PowerShell脚本，类似于下面的代码。

 using (mPowershell = PowerShell.Create()) 
 {
        mPowershell.AddScript(GetScriptText(mStep), true);
        SetPowershellVariables(mPowershell);
        output = new PSDataCollection<PSObject>();
        output.DataAdded += new EventHandler<DataAddedEventArgs>(Output_DataAdded);
        mPowershell.InvocationStateChanged += new EventHandler<PSInvocationStateChangedEventArgs>(Powershell_InvocationStateChanged);
        IAsyncResult asyncResult = mPowershell.BeginInvoke<PSObject, PSObject>(null, output);      
}

正如预期的那样，我遇到了错误，我想调试它们。

有没有办法，无需进入powershell脚本并每两行放一个Write-Host $somevariable，一步一步调试这个脚本？

我应该提一下脚本本身不能独立运行，C＃代码将变量添加到脚本的运行空间。

可以使用脚本Add-Debugger.ps1。 UI非常原始，只是一个输入对话框和一个输出控制台，您必须在脚本中添加一些临时代码才能进行调试。但是，如果没有更好的选择，这样的调试器仍可以正常工作。

添加到脚本以添加和触发调试的临时代码

# Add debugger with file output shown in a separate console.
# <path\> may be omitted if Add-Debugger.ps1 is in the path.

<path\>Add-Debugger.ps1 $env:TEMP\debug.log

# set some breakpoints
$null = Set-PSBreakpoint ...

从现在开始，当触发断点时，会显示调试器输入框。键入命令，检查变量，在输出控制台中查看输出。可用命令集：

s, StepInto  Step to the next statement into functions, scripts, etc.
v, StepOver  Step to the next statement over functions, scripts, etc.
o, StepOut   Step out of the current function, script, etc.
c, Continue  Continue operation (also on empty input).
q, Quit      Stop operation and exit the debugger.
?, h         Write this help message.
k            Write call stack (Get-PSCallStack).
K            Write detailed call stack using Format-List.

<n>          Write debug location in context of <n> lines.
+<n>         Set location context preference to <n> lines.
k <s> <n>    Write source at stack <s> in context of <n> lines.

w            Restart watching the debugger output file.
r            Write last PowerShell commands invoked on debugging.
<command>    Invoke any PowerShell <command> and write its output.

如何调试从C＃执行的powershell脚本？
