[.NET] 如何運用VB.NET讀取EXCEL某一欄位的資料

[daviddoffabc (當我孤單想找人陪)]

Dim oExcel As Object
        Dim oBook As Object
        Dim oSheet As Object

        'Start a new workbook in Excel
        oExcel = CreateObject("Excel.Application")
        oBook = oExcel.Workbooks.open("c:\book1.xls")
        oSheet = oBook.Worksheets(1)
        oExcel.visible = True

        oExcel.workbooks.Range("A1").value = "John"===>出現錯誤訊息

        oExcel.Quit()
