使用命令行参数从C＃执行PowerShell脚本

我需要从C＃中执行PowerShell脚本。该脚本需要命令行参数。

到目前为止，这是我所做的：

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可以是类似路径的内容，也可能包含空格。

我没有这个工作。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);

然后您可以添加参数

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

最后

pipeline.Commands.Add(myCommand);

这是完整的，已编辑的代码：

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));

脚本的内容为：

$someVariable = "StringToBeVerifiedInAUnitTest"
$someVariable

我在将参数传递给Commands.AddScript方法时遇到麻烦。

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到的集合中来解决此问题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();
}

您也可以将管道与AddScript方法一起使用：

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;

它需要一个字符串，以及您传递的任何参数。

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;
}

如果您使用过以下方法，则可以使用以下方法将参数添加到脚本中

pipeline.Commands.AddScript(Script);

这是使用HashMap作为参数的，键是脚本中变量的名称，而值是变量的值。

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

填充变量方法为：

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，您可以轻松地向脚本中添加多个参数。我还注意到，如果要从脚本中的变量获取值，如下所示：

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

//结果是v的名称

您必须按照我的说明进行操作，因为出于某种原因，如果您按照Kosi2801的建议这样做，则脚本变量列表中不会包含您自己的变量。

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

该代码段是

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。检查收藏确实很方便。用户是PowerShell脚本返回的对象类型。
