C# Powershell删除6天以前的文件夹

我必须使PS脚本集成到我们的自动化软件。我是PS的初学者，我做了一些尝试，但仍然没有成功。这是我的任务。 我有一个参数将用作输入参数。这将是远程磁盘路径 %setupRootPath%。该目录有多个子目录，如Beta、Testing、Release等。每个子目录都有项目名称。在持续集成系统中，每个项目都有构建名称，所以最后我得到了

%setupRootPath%\Beta\ProjektA\Build1000 %setupRootPath%\Beta\ProjektA\Build1003 %setupRootPath%\Beta\ProjektA\Build1004 %setupRootPath%\Beta\ProjektB\Build1007 %setupRootPath%\Beta\ProjektB\Build1008 %setupRootPath%\Beta\ProjektB\Build1009 %setupRootPath%\Beta\ProjektB\Build10010 %setupRootPath%\SystemTesting\ProjektA\Build1002 目前有数百个项目，我编写了C代码来满足我的需求，但是如果我可以通过PS而不是C使用调度程序来运行它，那就太好了

这是C代码

class Program
{
    const string rootDirPath = @"\\pcName\AutomationProcess\Deployment";
    const int keepNum = 1;
    const int deployDepth = 2;

    static void Main(string[] args)
    {
        var delDir = new DirectoryInfo(rootDirPath);
        var currentDateTime = DateTime.Now;

        int currentDetph = 0;
        var deployPathes = new Dictionary<DirectoryInfo, int>();
        GetDeployDirectories(delDir, currentDetph, deployPathes);

        foreach (var projektDir in deployPathes.Keys)
        {
            var dirInfoArray = projektDir.GetDirectories();
            if (dirInfoArray != null)
            {
                var sortedDeploymentDirs = from d in dirInfoArray
                                           where (currentDateTime - d.LastWriteTime).Days > 6
                                           orderby d.LastWriteTime
                                           select d;
                var deploymentDirsArray = sortedDeploymentDirs.ToArray();
                if (deploymentDirsArray.Length > keepNum)
                {
                    for (int i = 0; i < deploymentDirsArray.Length - keepNum; i++)
                    {
                        Console.WriteLine("Delete: {0}", deploymentDirsArray[i].FullName);
                    }
                }
            }
        }
    }

    private static void GetDeployDirectories(DirectoryInfo currentDirectory, int currentDetph, Dictionary<DirectoryInfo, int> resultDictionary)
    {
        currentDetph++;

        foreach (DirectoryInfo subDir in currentDirectory.GetDirectories())
        {
            if (currentDetph < deployDepth)
            {
                subDir.Refresh();
                GetDeployDirectories(subDir, currentDetph, resultDictionary);
            }
            else if (currentDetph == deployDepth)
            {
                resultDictionary.Add(subDir, currentDetph);
            }
        }
    }
}

我想这就是你想要的。您当然可以从代码的角度提高效率，或者轻松地将其转换为函数，但我试图使其可读

# Your input parameter
$setupRootPath = "\\pcName\AutomationProcess\Deployment\"

# Retrieve the top level directories (Beta, Testing, Release, etc.).
Get-ChildItem $setupRootPath | Where-Object {$_.PSisContainer -eq $true} | ForEach-Object {
    $topDir = $_

# Pull the list of projects in the current top level dir.
    Get-ChildItem $topDir | Where-Object {$_.PSisContainer -eq $true} | ForEach-Object {
        $projectDir = $_

#Get the list of build folders, sorting by LastWriteTime, skipping the most recent, where the file is older than 6 days; and delete the remaining items.
        Get-ChildItem $projectDir | Where-Object {$_.PSisContainer -eq $true} | Sort-Object LastWriteTime -Descending | Select-Object -Skip 1 | Where-Object {((Get-Date)-$_.LastWriteTime).TotalDays -gt 6} | Remove-Item

    }
}

如果您已经有一个C语言的工作程序，为什么不直接从powershell脚本调用它呢？用于功能更改。更改TeamCity步骤中编写的脚本比维护C代码和应用程序更容易。非常感谢。因此，当我键入instad时，选择对象-跳过1 |选择对象-跳过$keepNum也应该起作用。但使用此解决方案，我无法配置构建项目的深度。不管怎样，我今天要试试。再次非常感谢：

# Your input parameter
$setupRootPath = "\\pcName\AutomationProcess\Deployment\"

# Retrieve the top level directories (Beta, Testing, Release, etc.).
Get-ChildItem $setupRootPath | Where-Object {$_.PSisContainer -eq $true} | ForEach-Object {
    $topDir = $_

# Pull the list of projects in the current top level dir.
    Get-ChildItem $topDir | Where-Object {$_.PSisContainer -eq $true} | ForEach-Object {
        $projectDir = $_

#Get the list of build folders, sorting by LastWriteTime, skipping the most recent, where the file is older than 6 days; and delete the remaining items.
        Get-ChildItem $projectDir | Where-Object {$_.PSisContainer -eq $true} | Sort-Object LastWriteTime -Descending | Select-Object -Skip 1 | Where-Object {((Get-Date)-$_.LastWriteTime).TotalDays -gt 6} | Remove-Item

    }
