C#Runspace Powershell(交互式)

Question

我正在尝试使用C#在运行空间中执行带有参数的Powershell文件.不幸的是我得到以下输出:

public string ExecuteCommandDirect(int psId, string psMaster, string psFile)
{
    String FullPsFilePath = @"C:\CloudPS\" + psFile + ".ps1";

    String PsParameters = FullPsFilePath + " -psId " + psId + " -psMaster " + psMaster + " -NonInteractive";

    // Create Powershell Runspace
    Runspace runspace = RunspaceFactory.CreateRunspace();

    runspace.Open();

    // Create pipeline and add commands
    Pipeline pipeline = runspace.CreatePipeline();
    pipeline.Commands.AddScript(PsParameters);

    // Execute Script
    Collection<PSObject> results = new Collection<PSObject>();
    try
    {
        results = pipeline.Invoke();
    }
    catch (Exception ex)
    {
        results.Add(new PSObject((object)ex.Message));
    }

    // Close runspace
    runspace.Close();

    //Script results to string
    StringBuilder stringBuilder = new StringBuilder();
    foreach (PSObject obj in results)
    {
        Debug.WriteLine(obj);
        stringBuilder.AppendLine(obj.ToString());
    }

    return stringBuilder.ToString();

}

我能做什么？

当前的c#代码.这需要执行将在PS文件中的命令,并且需要返回一个json字符串.

param([int]$psId = 0, [string]$psMaster = 'localhost');

$date = Get-Date -Format 'h:m:s' | ConvertTo-Json;

Write-Host $date;

exit;

PS代码:

public string ExecuteCommandDirect(int psId, string psMaster, string psFile)
{
    String FullPsFilePath = @"C:\CloudPS\" + psFile + ".ps1";

    String PsParameters = FullPsFilePath + " -psId " + psId + " -psMaster " + psMaster + " -NonInteractive";

    // Create Powershell Runspace
    Runspace runspace = RunspaceFactory.CreateRunspace();

    runspace.Open();

    // Create pipeline and add commands
    Pipeline pipeline = runspace.CreatePipeline();
    pipeline.Commands.AddScript(PsParameters);

    // Execute Script
    Collection<PSObject> results = new Collection<PSObject>();
    try
    {
        results = pipeline.Invoke();
    }
    catch (Exception ex)
    {
        results.Add(new PSObject((object)ex.Message));
    }

    // Close runspace
    runspace.Close();

    //Script results to string
    StringBuilder stringBuilder = new StringBuilder();
    foreach (PSObject obj in results)
    {
        Debug.WriteLine(obj);
        stringBuilder.AppendLine(obj.ToString());
    }

    return stringBuilder.ToString();

}

Answer 1

用Write-Output而不是Write-Host

Answer 2

如果您需要运行使用非关键 cmdlet 的脚本，例如需要存在成熟的 pshost 的 write-host，您可以向运行空间添加“假”函数，这些函数要么不执行任何操作，要么记录到文本文件（或你想要的任何其他东西。）在这里看到我的另一个答案：

如何在代码创建的 powershell shell 中执行脚本，其中包含 Write-Host 命令？
