使用命令行参数从C＃执行PowerShell脚本-Java 学习之路

我需要在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可以是类似于也可能包含空格的路径 .

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scriptfile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);

Here is the complete, edited code:

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，因为可能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

有没有机会我可以更清楚地了解Commands.AddScript方法的传递参数？

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

scriptFile =“C：\ Foo1.PS1”

parameters =“parm1 parm2 parm3”...可变长度的参数

解决了这个问题......将null作为名称，将param作为值传递给CommandParameters集合

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();
}

您也可以使用AddScript方法使用管道：

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;

它将采用一个字符串，以及您传递的任何参数 .

如果您使用，这是一种向脚本添加参数的方法

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fill变量方法是：

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，您可以轻松地向脚本添加多个参数 . 我还注意到，如果你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的名称

你必须按照我展示的方式去做，因为出于某种原因，如果你这样做，Kosi2801建议脚本变量列表不会填充你自己的变量 .

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;
}

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

代码的片段是

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 .
