錯誤讀取Excel中使用VB.NET

Question

我有這樣的代碼讀取Excel文件

Dim scheduleFileName As String 

    'Creating Excel Object 
    Dim fileName As String 
    fileName = "E:\Vb Deployment\scheduling\scheduleSheet.xlsx" 

    Dim objExcel As New Excel._ExcelApplication 
    Dim objWrkBk As Excel.Workbook 
    Dim objSht As Excel.Worksheet 
    Dim testdata As String 

    objWrkBk = GetObject(fileName) 
    ' or objWrkBk = objExcel.Workbooks.Open("C:\test.xls") 
    objSht = objWrkBk.Worksheets(0) 

    testdata = objSht.Cells(1, 1).Value.ToString() 

但它給在錯誤上線

objSht = objWrkBk.Worksheets(0) 

錯誤：未找到成員....

您能否讓我知道爲什麼我得到這個錯誤以及如何糾正它？

Workbook確實有會員Worksheets。唯一缺少的是類型轉換

objSht = CType(objWrkBk.Worksheets(0), Excel.Worksheet)
