我写了一个从数组中创建XLS文件的函数。一切都很好，但我在从数组中提取头时遇到了问题。
我的头在提取后是按字母顺序组织的，但我希望保持它们与输入数组相同的顺序。

function DoTheMagicExcel {
    [cmdletbinding()]
    Param(
        <# Array to work on #>
        [Parameter( Mandatory = $true)]
        [ValidateNotNullOrEmpty()]
        [Array]$MyArray,
        <# Its Excel Sheet name #>
        [Parameter(Mandatory = $true)]
        [ValidateNotNullOrEmpty()]
        [alias('Sheet')]
        [string]$MySheetName,
        <# Excel file name #>
        [Parameter(Mandatory = $true)]
        [ValidateNotNullOrEmpty()]
        [ValidatePattern("\.(csv|xls)$")]
        [alias('XlsFile')]
        [string]$MyExcelFile
    )
    Begin {
        <# Init them all #>
        $excel = new-object -comobject Excel.Application
        $excel.visible = $False
        $excel.DisplayAlerts = $False
        $XlsAlreadyExist = $False
        if (Test-Path $MyExcelFile) {
            Write-Output "Fichier Excel deja existant"
            $XlsAlreadyExist = $true
            $workbook = $excel.Workbooks.open("$PSScriptRoot\$MyExcelFile")
            $workbook.Worksheets.Add() | Out-Null
            $workbook.WorkSheets.item(1).Name = $MySheetName
            $MySheet = $workbook.Worksheets.Item($MySheetName)
        }
        else {
            $workbook = $excel.Workbooks.Add()
            $workbook.WorkSheets.item(1).Name = $MySheetName
            $MySheet = $workbook.Worksheets.Item($MySheetName)
        }
        $MyHeadercolumn = 1
        $StartRow = 2
    }
    Process {
        $MyArrayHeader = $MyArray | Get-member -MemberType 'NoteProperty' | Select-Object -ExpandProperty 'Name'
        foreach ($header in $MyArrayHeader) {
            $MySheet.cells.item(1, $MyHeadercolumn).font.bold = $true
            $MySheet.cells.item(1, $MyHeadercolumn) = $header
            $MyHeadercolumn++
        }
        foreach ($ThisRow in $MyArray) { ......

我是说这个

$AllBcksummary[1] |ft -AutoSize

$MyArrayHeader |ft -AutoSize

然后，当我创建我的Excel我不再保持其原来的顺序

foreach ($header in $MyArrayHeader) {
            $MySheet.cells.item(1, $MyHeadercolumn).font.bold = $true
            $MySheet.cells.item(1, $MyHeadercolumn) = $header
            $MyHeadercolumn++
        }
