自动实现查找目录是否存在 不存在就创建 目录下有指定文件就自动导入  代码怎么修正呢？
有三段代码：
怎么将三段代码融合呢？实现往指定目录里丢文件，代码自动导入并进行匹配字段值！


代码：查找是否有目录，如果没有就新建，如果有就查找是否有指定的文件存在
If FileSys.DirectoryExists("d:\\MyFolder") Then \'如果目录C:\\MyFolder存在
    MessageBox.Show("我存在哦")
    If FileSys.FileExists("d:\\MyFolder\\案件基本信息.xls") Then
        Messagebox.Show("文件已经存在!","提示")
    Else
        Messagebox.Show("文件不存在或已经被删除!","提示")
    End If
Else
    FileSys.CreateDirectory("d:\\MyFolder")  \'创建目录
    MessageBox.Show("我新建成功了")
End If


代码：实现导入指定文件表
Dim ip As New Importer
ip.SourcePath = "d:\\MyFolder\\案件基本信息.xls"" \'指定数据文件
ip.SourceTableName = "案件基本信息$" \'指定要导入的表
ip.NewTableName ="案件基本信息" \'导入后的表名
ip.Format = "Excel" \'指定导入格式
ip.Import()

代码：实现导入自动匹配对应的字段列值
Dim dlg As New OpenFileDialog
dlg.Filter = "Excel文件|*.xls;*.xlsx"
If dlg.ShowDialog =DialogResult.OK Then
    Dim t As Table = Tables("案件基本信息")
    t.StopRedraw()
    Dim Book As New XLS.Book(dlg.FileName)
    Dim Sheet As XLS.Sheet = Book.Sheets(0)
    
    Dim c As Integer
    For i As Integer = 0 To sheet.Cols.Count -1
        If sheet(0,i).text = "部门受案号" Then
            c = i
            Exit For
        End If
    Next
    \'msgbox("案号列=" & c)
    
    For n As Integer = 1 To Sheet.Rows.Count -1
        Dim r As DataRow = t.DataTable.Find("部门受案号 = \'" & sheet(n,c).text.trim() & "\'")
        Dim Isnew As Boolean
        If r Is Nothing Then
            r = t.DataTable.AddNew()
            Isnew  = True
        End If
        For i As Integer = 0 To sheet.Cols.Count -1
            Dim cname As String = sheet(0, i).text
            If t.Cols.Contains(cname) Then
                If Isnew = False AndAlso cname = "是否关联" Then Continue For
                r(cname) = sheet(n, i).Text
            ElseIf cname = "移诉意见" Then
                r("移送意见") = sheet(n, i).Text
            ElseIf cname = "移诉案由" Then
                r("移送案由") = sheet(n, i).Text
                r("涉嫌案由") = sheet(n, i).Text
            ElseIf cname = "审结情况" Then
                r("审结处理结果") = sheet(n, i).Text
            ElseIf cname = "办结日期" Then
                r("审结日期") = sheet(n, i).Text
            End If
        Next
    Next
    t.ResumeRedraw()
End If

有点甜老师 下面的代码可以实现d:\\MyFolder\\案件基本信息.xlsx这个目录下的这个文件自动导入了
如果这个文件下有多个不同名字的 甚至还有xls的文件  怎么实现便利当前目录下的所有Excel格式文件 全部自动导入呢？
