使用命令行参数从C＃执行PowerShell脚本

我需要从C＃中执行一个PowerShell脚本。 该脚本需要命令行参数。

这是我迄今为止所做的：

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“C：\ Program Files \ MyProgram \ Whatever.ps1”之类的东西。

该脚本使用命令行参数（如“-key Value”），而Value可以是可能包含空格的path。

我没有得到这个工作。 有谁知道如何将命令行parameter passing给C＃中的PowerShell脚本，并确保空间没有问题？

Answer 1

尝试创build脚本文件作为一个单独的命令：

 Command myCommand = new Command(scriptfile); 

那么你可以添加参数

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

最后

 pipeline.Commands.Add(myCommand);

这里是完整的编辑代码：

 RunspaceConfiguration runspaceConfiguration = RunspaceConfiguration.Create(); Runspace runspace = RunspaceFactory.CreateRunspace(runspaceConfiguration); runspace.Open(); RunspaceInvoke scriptInvoker = new RunspaceInvoke(runspace); 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scheme。 我只是想testing一下，如果执行PowerShell脚本成功，因为也许有人可能会改变政策。 作为参数，我只是指定要执行的脚本的path。

 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

任何机会，我可以得到更多的Commands.AddScript方法传递参数的清晰度？

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

scriptFile =“C：\ Foo1.PS1”

参数=“parm1 parm2 parm3”…可变长度params

解决了这个…传递null作为名称和参数作为值的CommandParameters集合

这里是我的function：

 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(); }

您也可以使用AddScript方法使用pipe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; 

它将采取一个string，并通过它的任何参数。

如果您使用了以下方法，可以将Paramaters添加到脚本中

 pipeline.Commands.AddScript(Script); 

这是使用HashMap作为参数，键是脚本中variables的名称，值是variables的值。

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

而填充variables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); } } } 

这样您可以轻松地将多个参数添加到脚本中。 我也注意到，如果你想从你的脚本中获得一个variables的值，就像这样：

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

//结果是v的名字

你必须按照我所展示的方式来做，因为如果你这样做，Kosi2801build议脚本variables列表没有被你自己的variables填充。

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。 检查收集真的很方便。 用户是powershell脚本返回的对象的types。

矿是更小，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; }
