如何读取dbf文件？

编程问答 2022-04-23

问题描述

我正在尝试读取 dbf 文件。

代码：

$cmd = New-Object System.Data.OleDb.OleDbConnection
$cmd.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;DataSource=E:\DATA\MailTvm\sample.dbf;Extended Properties=dBASE IV;User ID=Admin;"
$cmd.Open
$sqlCmd = $cmd.CreateCommand()
$query = "select name from sample"
$sqlCmd.CommandText = $query
$adp = New-Object System.Data.OleDb.OleDbDataAdapter($sqlCmd,$cmd)
$data = New-Object System.Data.DataSet
$adp.Fill($data) 
$data.Tables
$cmd.Close()

当我尝试运行此代码时，它显示以下错误：
