Question

我创建了一个脚本，弹出一个对话框，输入的值进入foreach。我不知道如何在正在运行的脚本中创建单个值并对其进行处理。虽然我知道这不是正确的方法，但它确实有效。现在我已经创建了一个循环来再次提示，目标是将每个值附加到csv中。我的问题是，在写入csv之前，原始变量值被放入提示中的下一个值覆盖。如何在循环对话框中构建每个条目并创建csv？

你可以在powershell脚本中看到我从对话框的输入值创建了$ x，然后我将脚本循环到一个重复对话提示的函数中。当它这样做时，它会覆盖$ x的第一个值。我想在将所有值写入csv之前弄清楚如何构建许多值。

此脚本是让用户输入一个组，针对Active Directory进行检查，然后生成CSV。

...更新##我能够解决它。我删除了原始测试代码并放入了最终产品。以下脚本创建一个表单，该表单要求Active Directory中的对象。它检查活动目录，然后输出到电子表格，并再次询问，直到取消。重复构建变量。

function ProcessOut ($x , $group) {
            $result = @()

            Foreach ($Line in $x){
                            $GroupName = "domain.local\" + $group
                            $OutList = New-Object System.Object
                            $OutList | Add-Member -type NoteProperty -Name "DisplayPath_GroupName" -value $GroupName
                            $OutList | Add-Member -type NoteProperty -Name "RuleName" -value "AutomaticApproval"
                            $OutList | Add-Member -type NoteProperty -Name "RuleClauses" -value '
                            $result+= $OutList
            }

            #Output to csv
            $outputfilepath = 'c:\users\technician\desktop\'

使用ArrayList或Array构建。在全局级别创建它，以便在代码中可以访问它。例如：

# Create an empty array outside of the loop
$myArray = @()

# Get all running processes
$processes = Get-Process

# for each process in the list of processes we are going to do something
foreach($process in $processes)
{
    # Create a Pipe separated string
    $myString = $process.Name + "|" + $process.Id

    # Add the process name to my array.
    $myArray += $myString
}

# Export the array to a CSV file
$myArray | Export-Csv -Path c:\myfile.csv

或者如果你不喜欢数组（我没有多少原因......）尝试一个列表......

将第二行替换为：

$myArray = New-Object System.Collections.ArrayList

用

替换第14行

$myArray.Add($myString) > $null

请注意，我将输出管道化为null。这是为了阻止它回显，这可能/可能对你没用。

希望这有帮助。
