Question

我们有一个PowerShell GUI，用于备份文件。该GUI包含多个复选框，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，该函数在单击“备份”按钮时被调用，然后使用每个复选框的Tag属性定义源路径和目标路径，并且该函数中的Tag是“ Split”，因此Powershell知道用作来源，以及用作目的地。

这很好用。问题在于，对于其中一个复选框，我们要备份多个路径，而不仅仅是Tag中定义的一个源。例如，当选中“ Folder3”复选框时，我们希望同时备份C：\ Src \ Folder3和D：\ Src2 \ Folder3。我们将如何做？ -是否可以向复选框添加更多标签？如果是这样，那么在ForEach循环中必须对Split进行哪些更改？

感谢您提供任何帮助！

您可以使用逗号运算符（.Tag）将,制成数组。

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

然后在您的函数调用中，您可以将每个标签传递到Foreach-Object中并进行相应处理。

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")
            }
        }
    }
}

RoboCopy ForEach循环是否带有标签？
