c#问题，请求帮助，能不能交流一下？

protected void initGrid()
    {
        DataTable dt = new DataTable();
        dt = Sql2000DB.Get_Table("select * from 用户   ");
        if (dt.Rows.Count < 1)
            dt.Rows.Add(dt.NewRow());
        this.GridView1.DataSource = dt.DefaultView;
        this.GridView1.DataBind();
    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        //跳转页面
        Response.Redirect("RYEdit.aspx");
    }
    protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        if (e.CommandName == "Del")
        {
            string Key = this.GridView1.DataKeys[Convert.ToInt32(e.CommandArgument)].Value.ToString();
            //删除商品信息
            Sql2000DB.ExecSql("delete from 用户 where 帐号='" + Key + "'");
            initGrid();
        }
    }

有哪些不明白的？initGrid主要用Sql2000DB数据库实例类读取数据到DataTable后设置GridView数据源后绑定显示数据

其他2个方法都有注释了

不太明白句意
