use csv reader like A Fast CSV Reader[^] to read csv. then you can bind gridview like below

C#

using System.IO;
using LumenWorks.Framework.IO.Csv;
void ReadCsv()
{
    // open the file "data.csv" which is a CSV file with headers
    using (CsvReader csv = new CsvReader(
                           new StreamReader("data.csv"), true))
    {
        gridview.DataSource = csv;
        gridview.DataBind();
    }
}

when you need to export gridview to csv, refer below answer
