Question

我正在使用OleDB连接到Accdb文件。但它显示错误

异常详细信息：System.ArgumentException：不支持关键字：'provider'。

来源错误：

在执行当前Web请求期间生成了未处理的异常。可以使用下面的异常堆栈跟踪来识别有关异常的起源和位置的信息。

我不知道为什么它仍然显示错误显示关键字未被支持：'提供商'

我的网站配置

   <connectionStrings>
    <add name="PPAPConnectionString" connectionString="Provider=Microsoft.ACE.OLEDB.12.0;Data Source=H:\ACCESS2013\TS16949_Linker.accdb" 
    providerName=".NET Framework Data Provider for OLE DB"/>
    </connectionStrings>

代码

Dim constr As String = ConfigurationManager.ConnectionStrings("PPAPConnectionString").ConnectionString
 Protected Sub GridView1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles GridView1.SelectedIndexChanged
Dim qry As String
qry = "Select * from pfd_op_type where id=" & GridView1.SelectedDataKey.ToString
Dim con As System.Data.OleDb.OleDbConnection
Dim cmd As System.Data.OleDb.OleDbCommand
con = New System.Data.OleDb.OleDbConnection(constr)
cmd = New System.Data.OleDb.OleDbCommand(qry, con)
Dim da As System.Data.OleDb.OleDbDataAdapter = New System.Data.OleDb.OleDbDataAdapter(cmd)
Dim dt As DataTable
dt = New DataTable
da.Fill(dt)
typ_code_Num.Text = dt.Rows(0)(0).ToString
Op_Typ_Name.Text = dt.Rows(0)(1).ToString

End Sub
