主题：条件打印

Dim Book As New XLS.Book(ProjectPath & "Attachments\订单.xls") '打开模板
Dim fl As String = ProjectPath & "Reports\订单.xls"
Dim Sheet As XLS.Sheet = Book.Sheets(0)
Sheet(3,9).Value = "<日期 = # " & Date.Today & "#>" '写入打印条件
Book.Build() '生成报表
Book.Save(fl)
Dim Proc As New Process
Proc.File = fl
Proc.Start()

我想把它改成打印条件为选定多行打印，不知如何设置

求助，谢谢！

问题已解决，非常感谢！
