powershell - 带有标签的 RoboCopy ForEach 循环？

问题描述

我们有一个 PowerShell GUI，用于备份文件。这个 GUI 包含几个复选框，每个复选框代表一个文件路径，可以根据需要选中或取消选中它们。我们有一个带有 ForEach 循环的函数，当单击备份按钮时调用该函数，然后使用每个复选框上的 Tag 属性定义源路径和目标路径，并且函数中的 Tag 是“Split”，所以 Powershell 知道什么用作源，以及用作目标的内容。

这完美地工作。问题是，对于其中一个复选框，我们有多个要备份的路径，而不仅仅是标签中定义的一个源。例如，我们希望在选中“Folder3”复选框时同时备份 C:\Src\Folder3 和 D:\Src2\Folder3”。我们将如何做到这一点？-是否可以向复选框添加更多标签？并且如果是这样，对于拆分，必须在 ForEach 循环中进行哪些更改？

提前感谢您提供的任何帮助！

解决方案

您可以.Tag使用逗号运算符 ( ,) 创建一个数组。

$checkboxfolder2.Tag = "C:\src\Folder2>C:\dest\Folder2","C:\src\Folder3>C:\dest\Folder3"

然后稍后在您的函数调用中，您可以将每个标签导入Foreach-Object并相应地进行处理。

function FILE_BACKUP {
$CheckBoxes = $CheckBoxFolder1,$CheckBoxFolder2,$CheckBoxFolder3

    foreach ($CheckBox in $CheckBoxes)
    {
        $CheckBox.Tag | Foreach-Object {
            $FilePath = $_.Split(">")
            if ($CheckBox.Checked) 
            {
                robocopy $FilePath[0] $FilePath[1] /njh /njs /ndl /np /tee |
                    ForEach-Object { $outputBox.AppendText($_ + "`r`n") }
            } 
            else 
            {
                $outputBox.AppendText("$($checkbox.Text) NOT SELECTED" + "`r`n")
            }
        }
    }
}
