就是这个用法啊，可以加上保存
Dim Book As New XLS.Book(ProjectPath & "Attachments\卷内目录.xls")
Dim Sheet As XLS.Sheet = Book.Sheets(0) '引用工作簿的第一个工作表
Dim fl As String = ProjectPath & "Reports\卷内目录.xls"
Book.Build() '生成细节区
Book.Save(fl) '保存工作簿
Dim App As New MSExcel.Application
Dim Wb As MSExcel.WorkBook =App.WorkBooks.Open(fl)
Dim Ws As MSExcel.WorkSheet = Wb.WorkSheets(1)
Dim Rg As MSExcel.Range = Ws.UsedRange
Rg.WrapText = True
Rg.EntireRow.AutoFit '自动调整行高
Wb.save
app.visible = True
