Set the DataKeyField in GridView as
 
<asp:gridview id="gvList" runat="server" datakeynames="Id" xmlns:asp="#unknown">
...........
</asp:gridview>
 
Then you can get the key value for each column as:
 
for (int i = 0; i < gvList.Rows.Count; i++)
    {
        Int32 key = Convert.ToInt32(gvList.DataKeys[i].Value.ToString());
    }
 
Or, if you are working between any cell-event you can use the object of DataGridViewCellEventArgs as
 
Int32 key = Convert.ToInt32(gvList.DataKeys[e.RowIndex].Value);

you can set multiple datakeynames by , separation.
and you can access this by GridView1.DataKeys[e.RowIndex].Values["ID"];
