由于我是 .NET 新手,因此我需要对以下代码进行解释。谁能给我解释?
protected void GridView1_Sort(object sender, GridViewSortEventArgs e)
{
GridView grid = sender as GridView;
DataTable dt = Session["List"] as DataTable;
string month = System.DateTime.Now.AddMonths(-3).ToString("MMMM");
if (dt != null)
{
dt.DefaultView.Sort = e.SortExpression + " " + GetSortDirection(e.SortExpression);
grid.DataSource = Session["List"];
grid.DataBind();
}
}
