我有一个代码用于从 excel 中检索每个数据以更新 dbf 文件。我使用 Microsoft.Office.Interop.Excel 读取每个列范围的数据。现在我想使用 oledb 更改连接 excel .. 如何检索每列的数据并将其设置为变量?这是我的 Microsoft.Office.Interop.Excel 代码。
xlApp = New Excel.Application
xlWorkBook = xlApp.Workbooks.Open(xlsName)
xlWorkSheet = xlWorkBook.Worksheets("sheet1")
xlRange = xlWorkSheet.UsedRange
endrow = xlRange.Rows.Count
For rCnt = 3 To endrow
Empno = xlRange.Cells(rCnt, 1).Value
totalhrs = xlRange.Cells(rCnt, 3).Value
latehr = xlRange.Cells(rCnt, 4).Value
Next
xlWorkBook.Close()
xlApp.Quit()
这是我的 oledb 连接。连接后,我真的不知道该怎么做才能获取数据。请帮助我...我希望stackoverflow中的某人可以帮助我。
Dim xlsConnect As System.Data.OleDb.OleDbConnection
Dim DtSet As System.Data.DataSet
Dim MyCommand As System.Data.OleDb.OleDbDataAdapter
Try
If (Path.GetExtension(xlsName) = ".xls") Then
xlsConnect = New System.Data.OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & xlsName & ";Extended Properties=""Excel 8.0;HDR=Yes;IMEX=2""")
ElseIf (Path.GetExtension(xlsName) = ".xlsx") Then
xlsConnect = New System.Data.OleDb.OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & xlsName & ";Extended Properties='Excel 12.0;HDR=YES;IMEX=1;';")
End If
MyCommand = New System.Data.OleDb.OleDbDataAdapter("Select * from [Sheet1$]", xlsConnect)
'looping data should be here
xlsConnect.Close()
Catch ex As Exception
MsgBox(ex.ToString)
End Try
