主题：数据库连接

请问老师，我在服务器的d:根目录有SQL数据库LYXX_XX，下面的代码怎么能连接这个数据库读写员工表的数据呢。

Select Case e.Path
    Case "AddNew.htm"
        If e.PostValues.Count = 0 AndAlso e.Files.Count = 0 Then
            Dim sb As New StringBuilder
            sb.AppendLine("<meta name='viewport' c>")
            sb.AppendLine("<form enctype='multipart/form-data' action='AddNew.htm' method='post' id='form1' name='form1'>")
            sb.AppendLine("姓名: <input name='xm' id='xm'><br/><br/>")
            sb.AppendLine("部门: <input name='bm' id='bm'><br/><br/>")
            sb.AppendLine("职务: <input name='zw' id='zw'><br/><br/>")
            sb.AppendLine("学历: <input name='xl' id='xl'><br/><br/>")
            sb.AppendLine("照片: <input type='file' name='zp' id='zp' multiple><br/><br/>")
            sb.AppendLine("<input Type='submit' name='Sumbit' id='Sumbit' value='确定'>")
            sb.AppendLine("</form>")
            e.WriteString(sb.ToString)
        Else
            Dim dr As DataRow = DataTables("员工").AddNew()
            Dim inms() As String = {"xm","bm","zw","xl"} '输入框名称数组
            Dim cnms() As String = {"姓名","部门","职务","学历"} '列名数组,注意列名和输入框必须一一对应,位置不能错乱
            For i As Integer = 0 To inms.Length -1
                dr(cnms(i)) = e.PostValues(Inms(i))
            Next
            If  e.Files.ContainsKey("zp") Then
                dr("照片") = e.Files("zp")(0)
                e.SaveFile("zp", e.Files("zp")(0), ProjectPath & "Attachments\" & e.Files("zp")(0))
            End If
            dr.Save()
            Dim sb As New StringBuilder
            sb.AppendLine("增加记录成功! <br/><br/>")
            sb.AppendLine("<a href='AddNew.htm'>继续增加</a>")
            e.WriteString(sb.ToString)
        End If
End Select
