VB.net中读取CSV到DataGrid

 新技术的发展有点应接不暇，用户的胃口则被吊得越来越高，软件开发的质量也越来越高，因此对程序员的代码质量也随之变高。回到正题，今天我要说的是有关读取CSV文件到DataGrid表中，因为我在好几个项目中都用到了，页面很简单。



    
 下面是实现代码：

    Private Sub btnFileLoad_Click()Sub btnFileLoad_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnFileLoad.Click
        Dim l_objStreamReader As System.IO.StreamReader
