C# Powershell脚本错误"；找不到“的重载”；LoadFromCollection"；并且参数计数为：“quot；“1”&引用；

我正在尝试使用LoadfromCollection将集合对象加载到excel文件中。我正在使用EPPLUS库来实现这一点。但我不断收到错误“无法找到“LoadFromCollection”的重载，并且参数计数为：“1”，因为我是PowerShell的新手，不知道如何解决该问题。另外，是否有其他方法可以使用EPPLUS库加载集合对象

$pkg = [OfficeOpenXml.ExcelPackage]::new($Path)
$ws  = $pkg | Add-WorkSheet -WorkSheetname 'test'

$DemoData = New-Object System.Collections.ArrayList

$DemoData = 1..10 | Foreach-Object{

        $BookID = Get-Random -Minimum 1 -Maximum 1000
        $Date = (Get-Date).adddays(-$BookID)

        New-Object -TypeName PSObject -Property @{
            Name = "Book$_"
            BookID = $BookID
            Date = $Date
        } | Select Name, BookID, Date
    }
$null = $ws.Cells['A1'].LoadFromCollection($DemoData)

是一种通用方法，具有以下特征：

public ExcelRangeBase LoadFromCollection<T>(
    IEnumerable<T> Collection
)

# PowerShell v5 and above.

$pkg = [OfficeOpenXml.ExcelPackage]::new($Path)
$ws  = $pkg | Add-WorkSheet -WorkSheetname 'test'

# Define a custom class with the properties of interest.
class Custom {
  [string]   $Name
  [int]      $BookID
  [datetime] $Date
}

[Custom[]] $DemoData = 1..10 | Foreach-Object{

  $BookID = Get-Random -Minimum 1 -Maximum 1000
  $Date = (Get-Date).adddays(-$BookID)

  # Create and output a [Custom] instance with the specified property values.
  [Custom] @{ Name = "Book$_"; BookId = $BookID; Date = $Date }

}

# Call .LoadFromCollection with the strongly typed array.
$null = $ws.Cells['A1'].LoadFromCollection($DemoData)
