使用c＃从asp.net中的gridview中删除行时出错

问题描述

protected void gridCountry_RowDeleting(object sender, GridViewDeleteEventArgs e)
    {
        
        obj1.CountryId = Convert.ToInt32(gridCountry.DataKeys[e.RowIndex]["CountryId"].ToString ());
        obj1.DataDeleteInsideAllTable();
        obj1.ddlCountryListgrid(gridCountry);
    }

obj1.CountryId = Convert.ToInt32(gridCountry.DataKeys[e.RowIndex][CountryId].ToString ());

为什么此特定行会出现以下错误？

Why this particular line gives following error ?
