我需要从 C# 中执行 PowerShell 脚本。该脚本需要命令行参数。

这是我到目前为止所做的:

RunspaceConfiguration runspaceConfiguration = RunspaceConfiguration.Create();

Runspace runspace = RunspaceFactory.CreateRunspace(runspaceConfiguration);
runspace.Open();

RunspaceInvoke scriptInvoker = new RunspaceInvoke(runspace);

Pipeline pipeline = runspace.CreatePipeline();
pipeline.Commands.Add(scriptFile);

// Execute PowerShell script
results = pipeline.Invoke();

scriptFile 包含类似“C:\Program Files\MyProgram\Whatever.ps1”的内容。

该脚本使用命令行参数,例如“-key Value”,而 Value 可以是也可能包含空格的路径。

我不让这个工作。有谁知道如何从 C# 中将命令行参数传递给 PowerShell 脚本并确保空格没有问题?

尝试将脚本文件创建为单独的命令:

Command myCommand = new Command(scriptfile);

然后你可以添加参数

CommandParameter testParam = new CommandParameter("key","value");
myCommand.Parameters.Add(testParam);

最后

pipeline.Commands.Add(myCommand);

这是完整的编辑代码:

RunspaceConfiguration runspaceConfiguration = RunspaceConfiguration.Create();

Runspace runspace = RunspaceFactory.CreateRunspace(runspaceConfiguration);
runspace.Open();

Pipeline pipeline = runspace.CreatePipeline();

//Here's how you add a new script with arguments
Command myCommand = new Command(scriptfile);
CommandParameter testParam = new CommandParameter("key","value");
myCommand.Parameters.Add(testParam);

pipeline.Commands.Add(myCommand);

// Execute PowerShell script
results = pipeline.Invoke();

我有另一个解决方案。我只想测试执行 PowerShell 脚本是否成功,因为也许有人可能会更改策略。作为参数,我只是指定要执行的脚本的路径。

ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.FileName = @"powershell.exe";
startInfo.Arguments = @"& 'c:\Scripts\test.ps1'";
startInfo.RedirectStandardOutput = true;
startInfo.RedirectStandardError = true;
startInfo.UseShellExecute = false;
startInfo.CreateNoWindow = true;
Process process = new Process();
process.StartInfo = startInfo;
process.Start();

string output = process.StandardOutput.ReadToEnd();
Assert.IsTrue(output.Contains("StringToBeVerifiedInAUnitTest"));

string errors = process.StandardError.ReadToEnd();
Assert.IsTrue(string.IsNullOrEmpty(errors));

脚本的内容是:

$someVariable = "StringToBeVerifiedInAUnitTest"
$someVariable

我在将参数传递给 Commands.AddScript 方法时遇到了麻烦。

C:\Foo1.PS1 Hello World Hunger
C:\Foo2.PS1 Hello World

scriptFile = "C:\Foo1.PS1"

parameters = "parm1 parm2 parm3" ... variable length of params

我通过将null名称和参数作为值传递给一个集合来解决这个问题CommandParameters

这是我的功能:

private static void RunPowershellScript(string scriptFile, string scriptParameters)
{
    RunspaceConfiguration runspaceConfiguration = RunspaceConfiguration.Create();
    Runspace runspace = RunspaceFactory.CreateRunspace(runspaceConfiguration);
    runspace.Open();
    RunspaceInvoke scriptInvoker = new RunspaceInvoke(runspace);
    Pipeline pipeline = runspace.CreatePipeline();
    Command scriptCommand = new Command(scriptFile);
    Collection<CommandParameter> commandParameters = new Collection<CommandParameter>();
    foreach (string scriptParameter in scriptParameters.Split(' '))
    {
        CommandParameter commandParm = new CommandParameter(null, scriptParameter);
        commandParameters.Add(commandParm);
        scriptCommand.Parameters.Add(commandParm);
    }
    pipeline.Commands.Add(scriptCommand);
    Collection<PSObject> psObjects;
    psObjects = pipeline.Invoke();
}

我的更小更简单:

/// <summary>
/// Runs a PowerShell script taking it's path and parameters.
/// </summary>
/// <param name="scriptFullPath">The full file path for the .ps1 file.</param>
/// <param name="parameters">The parameters for the script, can be null.</param>
/// <returns>The output from the PowerShell execution.</returns>
public static ICollection<PSObject> RunScript(string scriptFullPath, ICollection<CommandParameter> parameters = null)
{
    var runspace = RunspaceFactory.CreateRunspace();
    runspace.Open();
    var pipeline = runspace.CreatePipeline();
    var cmd = new Command(scriptFullPath);
    if (parameters != null)
    {
        foreach (var p in parameters)
        {
            cmd.Parameters.Add(p);
        }
    }
    pipeline.Commands.Add(cmd);
    var results = pipeline.Invoke();
    pipeline.Dispose();
    runspace.Dispose();
    return results;
}

您也可以只使用带有 AddScript 方法的管道:

string cmdArg = ".\script.ps1 -foo bar"            
Collection<PSObject> psresults;
using (Pipeline pipeline = _runspace.CreatePipeline())
            {
                pipeline.Commands.AddScript(cmdArg);
                pipeline.Commands[0].MergeMyResults(PipelineResultTypes.Error, PipelineResultTypes.Output);
                psresults = pipeline.Invoke();
            }
return psresults;

它将接受一个字符串,以及您传递给它的任何参数。

对我来说,从 C# 运行 PowerShell 脚本最灵活的方法是使用PowerShell.Create().AddScript()

代码片段是

string scriptDirectory = Path.GetDirectoryName(
    ConfigurationManager.AppSettings["PathToTechOpsTooling"]);

var script =    
    "Set-Location " + scriptDirectory + Environment.NewLine +
    "Import-Module .\\script.psd1" + Environment.NewLine +
    "$data = Import-Csv -Path " + tempCsvFile + " -Encoding UTF8" + 
        Environment.NewLine +
    "New-Registration -server " + dbServer + " -DBName " + dbName + 
       " -Username \"" + user.Username + "\" + -Users $userData";

_powershell = PowerShell.Create().AddScript(script);
_powershell.Invoke<User>();
foreach (var errorRecord in _powershell.Streams.Error)
    Console.WriteLine(errorRecord);

您可以通过检查 Streams.Error 来检查是否有任何错误。检查收藏真的很方便。用户是 PowerShell 脚本返回的对象类型。

如果您使用,这是一种将参数添加到脚本的方法

pipeline.Commands.AddScript(Script);

这是使用 HashMap 作为参数,键是脚本中变量的名称,值是变量的值。

pipeline.Commands.AddScript(script));
FillVariables(pipeline, scriptParameter);
Collection<PSObject> results = pipeline.Invoke();

而填充变量的方法是:

private static void FillVariables(Pipeline pipeline, Hashtable scriptParameters)
{
  // Add additional variables to PowerShell
  if (scriptParameters != null)
  {
    foreach (DictionaryEntry entry in scriptParameters)
    {
      CommandParameter Param = new CommandParameter(entry.Key as String, entry.Value);
      pipeline.Commands[0].Parameters.Add(Param);
    }
  }
}

这样您就可以轻松地将多个参数添加到脚本中。我还注意到,如果您想从脚本中的变量中获取值,如下所示:

Object resultcollection = runspace.SessionStateProxy.GetVariable("results");

//结果是v的名字

您必须按照我展示的方式进行操作,因为出于某种原因,如果您按照 Kosi2801 建议的脚本变量列表不会填充您自己的变量的方式进行操作。

这对我有用,包括参数包含空格的情况:

using (PowerShell PowerShellInst = PowerShell.Create())
        {

            PowerShell ps = PowerShell.Create();
            
            string param1= "my param";
            string param2= "another param";
            string scriptPath = <path to script>;

            ps.AddScript(File.ReadAllText(scriptPath));

            ps.AddArgument(param1);
            ps.AddArgument(param2);

            ps.Invoke();
         
        }

我发现这种方法非常容易理解并且非常清晰。
