主题：帮我看看导出excel

错误提示是什么？

通常必须在Build之后，定义Sheet，然后设置单元格内容：

Dim Book As New XLS.Book(ProjectPath & "Attachments\设备一览表.xls")
Dim fl As String = "E:\Desktop\设备一览表.xls"
Book.Build() '生成细节区
Book.Save(fl) '保存工作簿

Dim Sheet As XLS.Sheet = Book.Sheets(0)
Sheet(10，10).value = “内容”
Dim Proc As New Process '打开工作簿
Proc.File = fl
Proc.Start()
