在asp.net web中 csv数据导入到 dataTable出错

[sky0813]

在sap导出的csv数据，想在asp.net上导入到DataTable里。提示 “在选定的数据源上未找到名为“Purchase Order ID”的字段或属性。”，而用WPS保存下，又可以。是什么原因造成的？

...

Dim strConn As String = String.Format("Provider=Microsoft.Jet.OLEDB.4.0;Extended Properties='text;HDR=Yes;FMT=Delimited;CharacterSet=65001';Data Source='" & mp & "'")
'连接数据。 Data Source为CSV文件存在的目录
Dim conn As New OleDbConnection(strConn)
Dim dt1 As New DataTable()
Dim sql As String = "select * from (" + filename + ") "

conn.Open()
Dim dr As New OleDbDataAdapter(sql, conn)
Dim ds As New DataSet()
dr.Fill(ds, "table1")
dt1 = ds.Tables("table1")
If dt1.Rows.Count > 0 Then
Try
GridView1.DataSource = dt1
GridView1.DataBind()

Dim i As Integer
For i = 0 To GridView1.Rows.Count - 1
Dim txtPONum As String = (GridView1.Rows(i).Cells(1).Text).Trim
If txtPONum.Replace(" ", "").Trim = "" Then
GridView1.Rows(i).Cells(1).Text = GridView1.Rows(i - 1).Cells(1).Text
End If
Next
Response.Write("<script>alert('讀取數據成功！');</script>")
Catch ex As Exception
End Try

对比一下wps保存前后发生的变化

CSV是文本文件。不要使用ADO类。直接读行，简单稳定。 本人使用多年了。百分百稳定

一般很少人用VB吧！提示也很明确是列名不对
