用下面的代码，以后就不会出现不关闭的情况了。但无法做到你说的关闭特定excel文件的功能，最多是关闭所有的excel文档。
Dim Book As New XLS.Book(ProjectPath & "Attachments\订单.xls")
Dim file As String = ProjectPath & "Reports\订单.xls"
Book.Build() '生成细节区
Book.Save(file) '保存工作簿
Dim App As New MSExcel.Application
Dim Wb As MSExcel.WorkBook
try
wb = App.WorkBooks.Open(file)
Dim Ws As MSExcel.WorkSheet = Wb.WorkSheets(1)
With Ws.PageSetup
.PaperSize = MSExcel.XlPaperSize.xlPaperA4 '纸张大小
.CenterHorizontally = True '页面水平居中
.CenterVertically = True '页面垂直居中
.Zoom = False '以下设置将缩印在一页内
.FitToPagesWide = 1 '按照1页的宽度打印
.FitToPagesTall = 1 '按照1页的高度打印
End With
'App.Visible = True
Ws.PrintOut
catch ex As exception
msgbox("出错了")
finally
wb.save
wb.close
App.Quit
End try
