OLEDB将CSV导入VB.NET数据表读取’ – ‘为0

我在读取CSV文件和转换为VB.Net中的数据表时遇到问题.
如果CSV文件包含一个完整的“ – ”列,则在导入数据表时它们显示为“0”,整个列的格式为数字格式.

我写的代码是：

Public Function LoadCsvFile(filePath As String) As DataTable
    Try

        DTReadCSV = New DataTable

        Dim connection As System.Data.OleDb.OleDbConnection = New System.Data.OleDb.OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & Microsoft.VisualBasic.Left(filePath,InStrRev(filePath,"")) & ";Extended Properties=""text;HDR=Yes;FMT=Delimited""")

        Dim adapter As New OleDb.OleDbDataAdapter("SELECT * FROM [" + Microsoft.VisualBasic.Mid(filePath,"") + 1) + "]",connection)
        'Dim table As New DataTable()
        adapter.Fill(DTReadCSV)

        'now thats its nicely in a datatable 
        IntAmountRows = DTReadCSV.Rows.Count
        IntAmountColumns = DTReadCSV.Columns.Count


        'System.Diagnostics.Debug.Print(DTReadCSV.Rows.Item(1)(1).ToString)
        Return DTReadCSV

        Exit Function
    Catch ex As Exception
        MsgBox(ex.ToString())

        MsgBox(Err.Number & " " & Chr(13) & Err.Description)
    End Try
End Function

除了修改CSV文件之外,还有人可以更聪明地弄清楚如何解决这个问题,将“ – ”作为空白取出,目前这似乎是导入这些CSV文件的唯一漫长的方式.

非常感谢
