$objDoc.Range.（$startPosition，$endPosition）.Selection.Delete（）

-范围之后不应该有点

$WordPathSrc = “D:\Folder\Word.docx"
$objWord = New-Object -ComObject Word.Application
$objWord.Visible = $True
$objDoc = $objWord.Documents.Open($WordPathSrc)
$objSelection = $objWord.Selection
$startPosition = $objDoc.Bookmarks.Item("TEST_START").range.select()
$endPosition = $objDoc.Bookmarks.Item("TEST_END").range.select()
$objDoc.Range.($startPosition, $endPosition).Selection.Delete()
$objDoc.Save()
$objDoc.Close($true)
