从Excel 2003导入数据到dataTable [英] import data from excel 2003 to dataTable

问题描述

我正在使用以下代码将excel工作表导入到datagridview：

I am importing excel worksheets to a datagridview using the following code:

Private Sub Browsimportbtn_Click(sender As Object, e As EventArgs) Handles Browsimportbtn.Click
    Dim textpath As String
    Dim textpath1 As String

    Dim opf As New OpenFileDialog
    If opf.ShowDialog = 1 Then
        textpath = opf.FileName
        textpath1 = opf.SafeFileName
        textpath1 = textpath1.Remove(textpath1.Length -4,4)

        Dim cnexcell As New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & textpath & "; Extended Properties = ""Excel 12.0 Xml;HDR=YES"";")
        Dim cmdE As New OleDbCommand("SELECT * FROM Feuil1", cnexcell)

        Try

            Dim daoledb As New OleDbDataAdapter
            Dim dset As New DataSet


            daoledb.SelectCommand = cmdE
            daoledb.Fill(dset, "Feuil1")
            DGVmodele.DataSource = dset.Tables("Feuil1")

        Catch ex As Exception
            MsgBox(ex.Message)
        End Try

    End If

End Sub

上面的代码与<$ c $配合良好c> .XLSX 文件（2007年，2010年办公室...），但没有使用 .XLS ，我不知道问题出在哪里。

The code above is working well with .XLSX files (office 2007,2010...) but do not with .XLS and i don't know where is the issue.

有什么建议吗？

推荐答案

问题是

您要在连接字符串中指定 Excel 12 作为版本，与2007年或更高版本相关。尝试使用此函数来构建连接字符串

You are specifying the Excel 12 as a version in the connection string which is related to 2007 or higher. Try using this function to build the connectionstring

Public Function BuildConnectionString(Byval m_strExcelPath as String) As String
    If m_strExcelPath.Substring(m_strExcelPath.LastIndexOf(".")).ToLower = ".xlsx" Then
        Return "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & m_strExcelPath & ";Excel 12.0;HDR=YES;IMEX=1"
    Else
        Return "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & m_strExcelPath & ";Excel 8.0;HDR=YES;IMEX=1"
    End If
End Function
